Ask HN: What would you do with $100K cash?

If the answer is yes, you are absolutely right in not investing in individual stocks. Where can be Google in 20 years? Facebook? Tesla? You don't know and the owners don't know either.

The first thing that comes to mind would be a mixed index/bond approach using Vanguard ETF's although any company will do. If you go for a conservative approach you could invest 50% Vanguard all US market ETF, 30% Vanguard Whole bond market ETF and 20% Rest of the world ETF market. In a more venturous approach you could move the 50% up to 60% while adjusting bond and ROW markets. I am a hobbist investor as well and I would very much like to see the rest of opinions.

If you don't know what to do with it, don't do anything. Later, when you know what to do with it, you can do it. To put it another way, right now, you have insufficient information to make an informed decision. You'll have more information later, and if you don't spend the money now, $100k to put behind that informed decision.

BUT: there's reason to believe that the stock markets are currently near peak. Instead of investing all your money at once, you may want to do something called "dollar cost averaging", where you spread out your investment by putting a bit into the market every month for years. That way you get some of the benefit from a market that continues to rise in the short term but don't lose your shirt if it crashes hard three months from now.

Otherwise, personally, I would put 60% in low cost index funds like Vanguard, 20% in bonds and 20% in crypto, but that's because I have a high risk tolerance.

First of all. Warren Buffet, on his whole life made around 17% p.a. average returns. With 17% on your 100k, it's okayish money, but won't take you anywhere, even in a few decades. And his average will be much higher than yours, don't try to compete with him or a have high return. So, first give up that you can get rich by investing or that you can outperform the market by a wide-margin, or that you will even outperform it. What makes you rich is how much you can save and then convert it into assets that makes you money. With a few decades of saving an okay amount, investing like an adult you will get rich. So, focus on making more money and saving more.

So, now, what to buy with the money you make?

Don't try to make those calculations people do: Hmm. I will get this investment or this other because the other pays me 1% a.a. more.

Instead, your goal is to beat inflation, always. That way, you aren't at least losing money.

Now, there are different investment products. Stocks, ETFs, REITs, crypto, all the stuff you said.

Do some small research and find all the stuff you are excited about: tesla, play monopoly(REITs?) etc.

Get like 20 options at least, diversify a lot. Get also some government bounds and keep a percentage of your money as USD, so you can take opportunities. Go very diversified. Returns doesn't matter, losing money(vs inflation) does.

Now, invest 5%(and strive to get even lower) on each. If you aren't confortable with stocks, get ETFs, multiple ones. Buy the obvious stuff: not the one everybody is buying, but also not the one not anybody wants to buy(only crazy people that feels it is a casino). Do the obvious.

The more you diversify in different products, the better. Also, having money in your bank account is also good, as if the stock market crashes, your overall assets will definitely feel less pain.

Avoid selling. Once you buy something, stick to the end. Does it sound stupid? Yes it does, but it will make sure you are always very diversified. If something keeps you awake at night because you fear losing more money, or any money at all, it just means you aren't diversified enough.

Avoid trading, buying and selling or whatever, because that gives money to who owns the broker. The market will try to make you rotate your assets, don't fucking do it. It is a terrible idea.

I've been doing the above and learning more about fundamental analysis of companies(stocks). I know how to read balances well and have had a performance better than S&P 500 on my overall assets, but I consider it partially luck. I only invest in stocks which can give constant profits, have a good free-float this and that. You don't need to learn this crap unless you want to. I do it for fun.

If I do very well, I might make 2% p.a. than you, and this makes absolutely no difference in that amount of money. If I would instead learn how to do make wooden tables and sell them, I would make more money than what do I get 2% a.a. on my assets(and by now, I think I've accumulated a lot).

Never buy into those early retirement schemes frugal lifestyle people try to sell you. It is all bullshit, it won't make you happy.

Also, the most important thing: DO SPORTS. This is the best investment advice you will ever get. Get at least 3x a week physical activity, maybe even more.

You can make muchhhhhhh more money by being alive for longer.

Time will always beat returns, always! Also, having assets invested means you will carry some risk and the best way to deal with anxiety of risk is to practice sports. You might think that risk has to do with losing money, but it also happens when winning. Once I've made so much money with crypto(like years worth of work, even more!) that I couldn't sleep well, even though I do my sports and all and barely have any anxiety previously. Same happened other times, with AAPL stock... also lost some. So things will go up and down, if you are divers...

I'd do what others said and invest in S&P 500 index fund (Vanguard). But - I would personally go for a regular index fund and not an ETF because ETF's are too new in my opinion. Not enough history unlike VTSAX or VFIAX which are old enough, so I trust them a lot more (also a suggestion from Warren Buffett BTW). And - I would not use your $100K. That's the main difference... you already have this cash in hand, don't invest it. Keep it as a back up just in case you get in troubles for unexpected events in the future. $100K is a good amount for that because it's not too much but still a lot of money to survive. Indeed, start redirecting the money you save every month into your Vanguard index fund. That's it. Start doing that today, let's say $1000/month. Buy VTAX or VIAX with it every month no matter if the market goes down or up. It's called dollar cost averaging.

Benefits with this strategy - You maintain a nice buying power (your $100K), you're pretty much secured in case something bad happens, if the market crashes tomorrow, not a problem, you're only investing brand new money. Worst case scenario is your best case scenario today = $100k. Plus by doing dollar cost averaging, it's actually good when the market goes down a bit because you end up buying more with your $1000/month at a lower price.

That's it.

1- If you're Relentlessly Resourceful { find something at the intersection of what you're passionate about, a problem, and a global movement. Then, create a company around it. If you're frugal enough you've got a shot at failing with 3-5 products (however similar between them) with $100k }

else {

2- pick 4-8 Tech and Biotech public companies w a 3-20B market cap w compelling visions that have initially been backed from top tier VCs. 1 example: BOX

}

- if rolling average of VIX is below 15, all in on vanguard

- if it's above 15, choose from a basket of historically defensive stocks (Mcdonalds, Coke etc). Allocate more toward stocks with lower pearson correlation to the index in the past year.

- add hysteresis to taste

the idea is to avoid extended downturns while not really actively managing. This strategy backtests pretty well and it's what I use personally.
