A fun read along these same lines, about the origins of the Zimmerman Rule (which says that profits from improperly funded trades accrue to the broker): https://chicagoreader.com/news-politics/busted-6/
via the August 30th Money Stuff, that sort of thing still happens:

"The SEC's complaint alleges that, between July 1 and 6, 2022, Anthony opened a new brokerage account using a fraudulent application on which he overstated his personal income and then made $1 million in bogus deposits from his bank account, which held only nine cents at the time. The complaint also states that, before Anthony's deposits reversed for insufficient funds in his bank account, he used "immediate access" credit extended to him by his broker-dealer to purchase $199,956.65 in securities. According to the complaint, Anthony's broker-dealer discovered the scheme before Anthony could make any profits, froze his account, and liquidated his holdings."

Seems reasonable. Then again, what happens if someone robs my house, takes the cash he finds to the casino, and wins a million dollars before getting caught? Knowing how much political power casinos have, I wouldn't be surprised if the action itself violated their rules and meant they could repossess the winnings.
IIRC, the liquidation actually did yield $2k more than he'd paid for the securities. He just didn't profit.
Dan Aykroyd does not get the respect he deserves and the title of this article is just one example.
The title comes from the name of the rule. The rule is named after Eddie because his character is the one that came up with the idea.

I agree Dan is fantastic but I think the rule is correctly named.

Actually it was Jamie Lee Curtis who comes up with the idea, and Dan who explains the logistics of how it will work.
I do think this is debatable, but we find Dan, readying a shotgun, saying "well do you have any better ideas?" and Eddie says "the best way you hurt rich people is by turning them into poor people."

It is true that Jamie Lee then sees the news about the report, and they all kind of have a collective realization about it. I think it can be argued that they all played a role, but if you have to pick someone, I'd argue that Eddie's line is the beginning of the idea.

Actually, reflecting on it further, I think that if this were real life, I would personally give them all credit, but it being a movie, I give Eddie's character the most, if not all, the credit.

I honestly think OP is right, it's just called that because Eddie was the most famous person in the movie at the time as his career was on fire, and he's most closely associated with it. The movie doesn't really show whose idea it was.

But now you got me thinking about another question -- who actually delivered the crop report to the USDA? Beeks was locked in the cage, so someone had to actually deliver the real report. Who did that?

I believe He had a copy. He was paid by the dukes to get a copy before anyone else saw it?
No he was carrying the briefcase with the handcuffs because it was the real report and he was on his way to DC to deliver it.
I could believe that; I was born three years after the film came out, so I am less familiar with that sort of context.

I haven't seen it in a while, but Wikipedia's plot summary says:

> The group deliver the forged report to the Dukes in Beeks' place.

I think they like meet him in a parking lot and it's dark so they can't tell it's not him?

Maybe this is a good excuse to watch the movie again sometime soon.

Right, they pretend to be Beeks to deliver their fake copy of the report to the Dukes. But that still leaves the question of who delivered the real copy to the USDA, which they read live on the air, and which they were expecting to be delivered by Beeks.
This is going to haunt me. I recently discovered a major plot hole in Fletch (I know) and now this is going to bother me too.
> Maybe this is a good excuse to watch the movie again sometime soon.

I feel the same way.

I'm happy I managed to provoke such a conversation. If because of this, just one person interrupted their work so they could stream Trading Places, well... perhaps we've made the world a better place. Ahem.

edit: and I for some reason feel delighted that my post turned into one of those controversial ones that gets upvoted and downvoted multiple times for no apparent reason. Dan Aykroyd's greatness should provoke controversy. Is he merely great, or the greatest?

'or beats them to it'

Basically they got the report before the dukes and changed it.

Louis showed the need to get back at them. Billy showed the way to properly get back at them with no possible actionable item. Ophelia showed what the dukes were doing and a possible thing to get at them with. Coleman showed that they need to get that report first and find out which way it went.

They all played a part. They all even helped finance it.

It was a very nicely written piece with each character playing in character to help solve the problem proposed by the main character.

> It was a very nicely written piece with each character playing in character to help solve the problem proposed by the main character.

I fully agree with this, which is why because it's a movie, it being attributed mostly to the main character makes sense, but if it weren't, I'd think they all played a part.

Anyway my opinion on this is 100% irrelevant so I'm going to leave it at that. I think it's a great movie, all in all.

It seems like these attempts to enforce fairness/impartiality often hinge on making the information-release as simultaneous as possible... But I can't help but feel dissatisfied with that, it feels like a cheap-and-dirty fix.

It just shifts things from "free money to whoever has the best spy-network or paid preferential access" to "free money to whoever builds a system to place orders milliseconds faster than others."

It turns out that the speed of light its the limit to causality and your 'closeness' to the source is always going to matter.

Lets imagine it on a planetary scale, you have planets in this particular layout currently.

A - B - C

If planet A releases news, planet B will get the news and be able to reply to it before planet C and there no way to do anything about it unless you come up with superluminal travel.

Now, some number of months, years later as the planets orbit you can get A - C -B in which planet B would be left out.

You could try to make it fair by having planet A encrypt a payload to B and a payload to C such that the transmission time and decryption time from A - B is the same as A - C. You could need encryption that feeds the previous block to the next (so CBC), and some trusted computing solution such that additional compute cannot be added to accelerate the decryption.
This depends if you're doing full cycle trips of two way 'trading' to planet A.

You not only have the time for full information to get to planet C, you have to withhold information from B until planet C's reply is already in flight back to planet A.

I think this is more about which activities (ex: industrial espionage) ought to be economically rewarded and which should not.

It's true that "Being Much Closer On A Closer Planet" might someday be part of that debate, but I think we've got plenty of closer non-spacetime issues to tackle first.

(comment deleted)
There is a better kind of closeness, eg. for reports/financials, being on the inside and getting the information on human timescales (well ahead of the public)
It doesn't have to be for everything. Disclose whenever and disallow action on the information for a period of time. This is why company earnings are disclosed after the market closes for the day - everyone has several hours to receive the information and decide what to do.
Does that really help, though? During the trading day, many (I want to say most, but can't confirm it) trades don't affect prices; odd lots and trades internalized on certain trading platforms don't effect NBBO IIRC. On the other hand, pre-market and after hours trades of even single-digit shares can move the price. This is why volatility can be so high then, and why you'll often see things like stock prices moving 10, 20, 30% within a few moments of close. Sometimes it snaps back before the next trading day. Sometimes, it doesn't.
(comment deleted)
The easiest way to fix this would be to say (in an extreme case) trades can only happen on 4 hour boundaries (time to get from the sun to neptune).

So as long as news is released early in the period, then everyone has plenty of time to receive the information. Again assuming you're talking about planetary scale within the same solar system.

If you're talking about within the US or on earth, you simply give a buffer for speed of light to transit across the us and "very sufficient" time for computation/calculation.

There will always be some delta. Ie a company near wall st had 5mins minus 1 millisecond to calculate, while a company in california had 5 mins minus 100 milliseconds to calculate. But if they have 5 mins to digest and calculate the news, the difference those few milliseconds make isn't really important anymore.

Investing should prioritize making the correct decision over making the faster decision. Right now, too much of profit is simply being able to make the faster decision.

It's like playing an RTS against and AI with horrible strategy but has APM through the roof. Yes they're winning, but it's not really interesting or beneficial insights it's providing.

But if you have a strategy that can win with only 10 APM you must've come up with something really deep and insightful about the game.

You could mildly quantize the order processing to give everybody enough time to act on it, and eliminate a lot of unproductive HFT.
Yeah, another possibility might be an exchange where there is some time-fuzzing in the system, such as if every order gets a (provably) random hidden delay. This would discourage people trying to play around incidental timing issues in favor of bidding what they "really think is right."

I suppose users might try to avoid that by breaking up a buy/sell order into a bazillion tiny orders, but that could be curbed by transaction-costs.

The SEC and other regulators try to make markets fair and avoid corruption because otherwise people would sensibly stay away, and then the money would dry up.

That's how I understand it. And it feels like a leaky dam with fingers stuck all over it.

What are the major, huge, "no-one will go for that" changes that might simply replace the dam?

If we apply a Tobin Tax? If we time box trades to every five minutes? If we end trading on margin? Place derivatives under insurance law ?

Or is it that experienced players have a huge incentive to fleece inexperienced players and that's just the way of the world, and the casino needs to have really good pit bosses, or there is no casino?

Time box for trades is a very interesting idea that I've never heard of before. Would probably equalize the playing field by a lot, reducing the advantage firms have simply by being close to the market. Have there been serious discussions about this in the past? I wonder what the downsides would be, besides that it would hurt the bottom line of market makers
No matter what time box you choose, someone is not going to be able to react to information for longer than the time box. It introduces complexity for dubious benefit, IMHO.

And yes, this has been talked about endlessly. Heck, some people have proposed even further restrictions; for example, in practice, the first and last hours that the exchange are open tend to have the highest volume, so why not only keep the exchange open for those two hours?

> No matter what time box you choose, someone is not going to be able to react to information for longer than the time box. It introduces complexity for dubious benefit, IMHO.

If releases like this were scheduled for 30 seconds into a 5 minute box, basically any trader that cares would be able to react inside the box. We could say 99.9% for the sake of argument.

I can't exactly state whether it's a good idea overall, but the idea that it might not catch literally everyone doesn't really matter. It's an extreme example of letting the perfect be the enemy of the good, when it comes to this single aspect.

I personally tend to believe that the more complexity you introduce into systems like this, the more unintended consequences and more opportunities for shenanigans arise. I don’t think that five minute boxes moves the needle on societal good via the exchange. I am also not an expert.
Is a system where you only process orders every X minutes actually more complex? The current system is _full_ of stupid shenanigans specifically due to a lack of a timebox.
A computer can process your release in 4 minutes. However if your release is complex at all a human would not be able to figure it out.
A computer can process it in 4 seconds, but badly. Given 4 minutes I think a human with reasonable tools could do as good of a job as a computer.
That depends on what the information his, and the add on side effects. Some things are subtle and take a while for a human to figure out.
Warren Buffet has stated the markets should be open only one day per year before. I can't find his exact words though.

It would equalize the field. However it also means unexpected expenses cannot be handled. Furnace breaks, even though you have plenty of $$$ in stocks you are unable to get it fixed. (I know a retired person who was forced to buy a new car with cash because the bank didn't accept their > $million in investments as proof they could pay for a small loan)

I believe you're slightly mis-remembering; the quote that I'm aware of is "Only buy something that you'd be perfectly happy to hold if the market shut down for 10 years."

It's a statement about strategy, not about suggesting regulation.

He has said that type of thing a lot more often. I seem to recall the suggestion the market shutdown except for once a year as well. As I recall he admitted that it wasn't workable.

Or maybe I remember wrong.

This is correct and what’s lost in legislation their goal isn’t to make markets fair, it’s instead to make them inviting to capital. Though there is some overlap, they are very distinct incentives.
thats a great point. its fair in a 'pursuit of happiness' type of way.
> regulators try to make markets fair and avoid corruption because otherwise people would sensibly stay away

Cryptocurrency seems to refute this assumption. I'd be curious to see if these fairness regulations actually lower capital costs for companies more than they cost to comply with.

Sounds like you're talking about anti-latency arbitrage mechanisms, which aren't a new subject. The book Flash Boys talked about IEX, an exchange set up in Canada with an enforced minimum latency via propagation delay, just by having long coils of fiberoptic cable...

I don't think nanosecond-sensitive trading should be a thing, personally, but sweeping changes to the way security exchange works seems less likely than societal collapse. Most apparent experts insist that letting algorithmic money vacuums operate is "good for liquidity," and that there is no viable more-fair alternative. I don't really buy it. IMO the obstacles to something better are just public ignorance, industry inertia, and a deeply lacking interest in fairness, i.e. corruption.

> Most apparent experts insist that letting algorithmic money vacuums operate is "good for liquidity,"

You do realize those "apparent experts" are mainly those ones making money from it (or are closely associated with them)?

I also think the best policy national is for everyone to pay me $10 daily. And I can give you hundreds of pages in support as to why that is. And after I've made a few tens of millions of that, I can buy you an army of "apparent experts" that will agree with it.

And for starters, by ensuring that money is moving daily (to my pocket), regardless of if a person is sitting on the couch at home watching tv all day, "greatly increases liquidity".

I do realize that "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!"

I'm likewise very aware that that's a factor in people's defense of the status quo.

What if you disclosed private information on twitter before trading. Would that still break the law? "Just heard jelly bean futures are going down. Going to sell now"
Yes, it would break the law because the law is written based on how you got the information, not based on if the information is disseminated. The law is that you can't use misappropriated government information.
Yes, since you are using insider information.

And before spitballing further, consider the 'good faith' rule. Are you acting on the insider information in good faith? If not, do not do that thing.

Let's make it a bit more interesting and say the Twitter account is a paid subscription for $1MM/mo. I was following his Twitter account and knew that he seemed to have a good instinct for when things were going down, but it can't be proven that I knew that the account was disclosing non-public government information.

Should I be expected to know that was information improperly obtained, particularly because of the massive premium cost of the subscription implies that it's possible that something improper is going on?

How long before. There are often rules that you have to disclose such data a specific amount of time before you trade - often a week or two. There is an exception for trades you scheduled far enough in advance that they couldn't have been insiders (ie if you want to pay your kids' Harvard tuition you can schedule the trade months in advance - you won't have insider information anyway)

If everybody expects you to disclose that information in twitter than you are okay. However if the information is supposed to be disclosed on a SEC form (8k, and 10q are the most likely) than putting it on twitter first could get you in trouble even if you don't trade at all since someone who watches the SEC filings will not see your twitter notice)

Seems like there isn't really an issue being raised in this article. There clearly needs to be close scrutiny on the journalists being given the information in advance, but given the fact that its provided in a "lockup room" it seems like that's the case. If everyone can access the information at the same time, even if its via these journalists, I don't really see an issue.
I don’t think the article intends to raise an issue. It simply explains various ways that the rule is dealt with. That the lockup room exists is exactly for that purpose.
Reminds me of Ep 123 of Darknet Diaries.
There’s one thing that’s a guarantee in life:

Information is where Money and Relativity meet.
> (They followed the basic prototype for selling short. That just means you sell high before you buy low. How? First you borrow and sell. Then you wait for markets to drop, buy, and return what you borrowed.)

Minor nitpick here, but with futures you aren't shorting in that you never borrow. You are simply writing a futures contract which makes you the seller. So when you write the contract you are obligated to sell/deliver at that price on the futures delivery date.

this is a bit different from options in that a futures contract buyer has to take delivery and the seller has to deliver. Where as for an options contract the buyer has the right but not the obligation to exercise it.

You then cancel your obligation out by later buying a contract that obligates you to take delivery on the delivery date. In this case since you bought the contract later when the market crashed you are buying delivery at a lower price, thus fulfilling your delivery obligations and locking in a profit.

No shorting or borrowing happens in this instance.

A few random fun facts about futures.

1) there aren't insider trading rules like there are for equities. This makes sense when you consider that McDonalds can move the market if they chose to create a new product. Not allowing McDonalds to trade in the futures market would mean they can't hedge their input needs.

Similarly oil companies use futures to hedge their selling prices for oil. If you had insider trading laws like we do with equities they couldn't trade as they have insider knowledge of their market moving needs.

2) A few years ago oil traded negatively for a month, this meant you actually got paid to take delivery of oil. This happened not because oil was worthless( it was still worth the market rate) but because you need to take delivery of the oil on the delivery date.

And oil can't just be stored in the your garage. You need to have pre arrange storage in Cushing, Oklahoma or arrange for a rail car to ship your oil out on that exact date.

As you would expect oil storage being heavily regulated is finite and rail cars are expensive and booked months in advance so once the storage and rail delivery options were full you'd have to pay someone else for their prearranged storage or rail delivery.

And the holders of these storage and shipping options were able to charge a ransom for them as contract buyers had to take delivery and thus had to arrange storage or shipping. More than a few retail investors got hosed on this buy buying futures when the price dropped to half of what a barrel was worth not fully realizing that a) they'd need to pay for storage and b) not fully realizing that the price of oil didn't have a floor at zero, it could infact go negative.

When you say "there aren't insider trading rules like there are for equities" Do you mean there aren't any at all or that they are different?

I could see there being different rules like "primary" players are allowed but "secondary" players aren't allowed. That way McDonalds could buy pork futures before the McRib comes back, but the CEO can't use insider info to front run pork futures before the McRib comes back.

> When you say "there aren't insider trading rules like there are for equities" Do you mean there aren't any at all or that they are different?

Closer to non-existent. Same for foreign exchange.

> different rules like "primary" players are allowed but "secondary" players aren't allowed

Trying to delineate markets this way is how Enron became a quasi hedge fund while many banks busy themselves running warehouses. One set of rules is simpler and more efficient, particularly for something as utilitarian as commodities, where you're concerned with efficiency more than fairness.

> the CEO can't use insider info to front run pork futures before the McRib comes back

I don't think there would be a commodities violation in this. There could be a securities violation, in that the CEO is misappropriating gains that belong to the shareholders they have a fiduciary obligation to.

It's not a minor nitpick. The author mis-explains what futures contracts are in a very fundamental way.

There's an NPR article about this same topic: https://www.npr.org/sections/money/2013/07/19/201430727/what...

"Winthorpe and Valentine have contracts allowing them to buy millions of pounds of orange juice in April for 29 cents a pound, and to sell it for $1.42 a pound. They sold high and bought low. They're rich. The Dukes made the opposite bet and went broke."

I've read books about high frequency trading and the like, but what is the mechanism by which information from an audio feed "a few seconds" in advance of another is turned into profitable trades? Is a human involved? If so, do they prepare trades to suit both directions and then hit the right button as soon as they hear the right thing on the feed?
Here is an article about the events mentioned, that has some more detail: https://www.ft.com/content/17bc0ef6-2282-11ea-92da-f0c92e957...

> up to 10 seconds before live comments were broadcast on television or internet streams

Ten seconds is a long enough time for your "if so," which is what I would guess happens in this specific circumstance.

I am an amateur in this space, but in general there are a lot of misconceptions about HFT, because the details are highly technical. See the debates over "paying for order flow," for example. I think it's hard to characterize these systems because, well, they are proprietary. In my understanding, most HFT folks rely on a combination of fundamental and technical analysis, more than sentiment analysis. HFT is more of a game of "make a small amount of money trading all the time" than "wait until some news breaks and reacts to it."

It’s amazing to think that Eddie Murphy was only:

- 20 years old in 48-Hours

- 21 years old in Trading Places

- 22 years old in Beverly Hills Cop

And only 19 years old on SNL and hugely famous.
