Unfortunately a lesson I had to learn for myself. Hopefully I can pass it on to the next generation, but I fear they'll have to learn it for themselves too. Don't pick individual stocks people, buy broad index funds at most.

We are in the industry, and perhaps we indeed know better.

> buy broad index funds at most

That gives slightly better than the inflation rate ( Canada ).

jonasdegendt•1h ago
> That gives slightly better than the inflation rate ( Canada ).

What do you mean? Over the last year any one of the index funds I'm in has beat inflation by a factor of five, some beat inflation by an order of magnitude. My worst performer is an iShares world fund, which generally has more temperate gains, clocking in at 10% YoY.

Looking at Canadian indices such as $VCN, it's the same story.

betaby•1h ago
As of October 2025, in the previous 30 Years, the Vanguard FTSE Canada All Cap Index (VCN.TO) ETF obtained a 8.72% compound annual return.

~2x better than the official inflation over the same 30 years. I don't see the factor of five or order of magnitude. Also those gains are taxable.

YZF•55m ago
If you're in Canada you almost certainly want to diversify from Canadian indices. US markets have tended to outperform.

Indices can return >20% one year and -10% other years. I think OP is talking recently, not over 30 years. Over the long term indices like the S&P 500 tend to have a real return of 6-7% ...

osti•17m ago
That's the biggest problem I have with the recommendation to buy indices as if indices grow at >8% annually is an natural law.

Many (most) indices of countries in the world performed way less than 8%. US performed exceptionally well over almost a century so people are starting to take it as a natural law. If I buy US index, I'm still putting a directional bet on US stock market performing at an exceptional rate.

throw0101d•16m ago
> If you're in Canada you almost certainly want to diversify from Canadian indices. US markets have tended to outperform.

If you buy "all-in-one" VEQT/XEQT (100% equities) you are buying an index funds of index funds: all Canadian equities, all US equities, EU, etc:

If you don't want 100% equities, there are VGRO/XGRO (80/20), VBAL/XBAL (60/40), VCNS/XCNS (40/60), etc.

I would have said this, but someone responded with a comment that stuck with me:

We’re on a forum of an incubator whose goal is investing in high risk startups to find the next unicorn. So there are probably people here who feel the same way about investing.

While the average outcome of indexes is probably better, the best case outcome of an individual stock is probably better.

It’s lower likelihood and not as repeatable, but for some people, that’s the strategy they want.

throw0101d•40m ago
> While the average outcome of indexes is probably better, the best case outcome of an individual stock is probably better.

Most stocks suck:

> We study long-run shareholder outcomes for over 64,000 global common stocks during the January 1990 to December 2020 period. We document that the majority, 55.2% of U.S. stocks and 57.4% of non-U.S. stocks, underperform one-month U.S. Treasury bills in terms of compound returns over the full sample. Focusing on aggregate shareholder outcomes, we find that the top-performing 2.4% of firms account for all of the $US 75.7 trillion in net global stock market wealth creation from 1990 to December 2020. Outside the US, 1.41% of firms account for the $US 30.7 trillion in net wealth creation.

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3710251

> Four out of every seven common stocks that have appeared in the CRSP database since 1926 have lifetime buy-and-hold returns less than one-month Treasuries. When stated in terms of lifetime dollar wealth creation, the best-performing four percent of listed companies explain the net gain for the entire U.S. stock market since 1926, as other stocks collectively matched Treasury bills. These results highlight the important role of positive skewness in the distribution of individual stock returns, attributable both to skewness in monthly returns and to the effects of compounding. The results help to explain why poorly-diversified active strategies most often underperform market averages.

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2900447

And it's not always the same 2-4% of stocks: a stock may shoot up in value, and if you're holding it at that time to can capture that, but once it has already gone up it may perform average-to-poor going forward. At that point, if you're still holding on it, it will be a drag on your (average) returns.

Esophagus4•6m ago
I don’t disagree at all (I have no individual stocks, only indexes). The average retail investor doesn’t beat the market.

However, the top 10% of retail traders actually can generate consistent returns.[1]

Consider that MSFT has gone up 10x over the last ten years while the S&P has risen 4x. Ethereum has risen 2500x in that period. TSLA has risen 270x.

Not saying these returns are typical, but I can imagine that a highly aggressive retail investor could, with a few good trades and a lot of confidence, do incredibly well and end up with a life-altering amount of money. Obviously, the chances of both entering AND exiting the trades to capture all of that is low.

Again, not my style, but I respect those who want to place their bets.

If you do want to dabble in individual stocks, keep it as a small percentage of your portfolio that you’re willing to lose.
YZF•45m ago
And certainly don't buy individual stocks because of FOMO or day trading or some wishful thinking.

I pretty much only invest in indices except for rare small fun picks where I'm ok with losing. But over the years there were certainly times where this was a too conservative stance. My small bets have outperformed my conservative portion - by a lot. That said, those times were I am confident in those bets are rare, like a few times a decade.

The successful crypto bros are mostly either issuers or crooks. That way they escape the natural tendency of all crypto other than Bitcoin and Ethereum to go down.

Something that is not mentioned: The psychological burden when you check your portfolio multiple times a day.

It can become an addiction akin to sports betting. Your mind is constantly occupied by the market and how it’s going. It takes a heavy attention toll on anything other you want to focus on.

I have learned my lesson. I buy the index and look at my portfolio 1-2 times a year and focus my mind on other things.

You just did it in the wrong order:

1. Buy the index

2. Check your portfolio multiple times a day

Now it's less like gambling and more like being entertained looking at your fish tank.

alwa•1h ago
1) buy the index (and maybe some bonds)

2) find the friend, colleague, or housemate who’s a degenerate market gambler

3) let their Hot Picks and Levered Options serve as your fish tank.

You don’t need to block all ads. Even stopping the bottom 50% cleans up the internet so much.

You know how to find an adblocker if you read HN. If you don’t want to use one, that’s your choice but it’s disingenuous to complain about blocking 100% of ads.

Unless you're a full time quant with a high deflated sharpe ratio you have no business making trades. It's not an investment to speculate on unpredictable price, that's called gambling, as Eugene Fama explained. Investments yield income. A stock buyback is not better than a dividend.

Index funds and small investments in things that are still early that you believe in / care about are the way to go.

Day trading and dabbling in $GME, shitcoins, post-2023 NVIDIA, individual stocks, etc. are all bubbles.

Day trading is a scam. Trading firms are more than well-positioned to eat retail's lunch, every single time.

Day Traders only exist because of this. Bull markets allow them to exist.
pessimizer•1h ago
The main thing current bull markets make you feel is far less subsidized by the government than you really are.

There are a lot of people playing at being upper middle class right now, living large paycheck to large paycheck, and they don't realize that the people whose lifestyles they're emulating are getting money for nothing. If the layoffs start getting deeper i.e. if AI takes off OR if AI does not take off, they'll be at the food banks in a year.

We'll see what happens in society when the comfortable middle class that makes all of the demands in our political system gets halved.

If one has time, a few books I would highly recommend:

The Intelligent Investor by Ben Graham

Security Analysis by Graham and Dodd

Common Stocks and Uncommon Profits and Other Writings by Philip Fisher

The Little Book That Still Beats the Market by Greenblatt

Warren Buffett's annual letters

Actually, anything by Ben Graham or Joel Greenblatt is worth reading if one is interested in the investing world. I don't know if I'll ever invest enough time doing fundamental analysis and actively (value) investing but I am making my way through these just to understand value investing properly.

throw0101a•57m ago
> Warren Buffett's annual letters

Buffett says to buy index funds.

> Actually, anything by Ben Graham or Joel Greenblatt is worth reading if one is interested in the investing world.

Ben Graham in the last interview before he passed ("A Conversation with Benjamin Graham", Financial Analysts Journal, Vol. 32, No. 5 (Sep. - Oct., 1976), pp. 20-23):

>> In selecting the common stock portfolio, do you advise careful study of and selectivity among different issues?

> In general, no. I am no longer an advocate of elaborate techniques of security analysis in order to find superior value opportunities. This was a rewarding activity, say, 40 years ago, when our textbook "Graham and Dodd" was first published; but the situation has changed a great deal since then. In the old days any well-trained security analyst could do a good professional job of selecting undervalued issues through detailed studies; but in the light of the enormous amount of research now being carried on, I doubt whether in most cases such extensive efforts will generate sufficiently superior selections to justify their cost. To that very limited extent I'm on the side of the "efficient market" school of thought now generally accepted by the professors.

* https://www.jstor.org/stable/4477960

* https://www.bylo.org/bgraham76.html

Graham was also of the opinion that analysis is of questionable use even in 1976 (nevermind now, ~40 years later).

thisisit•46m ago
I have read both The Intelligent Investor or Security Analysis and I can't say there is any value - no pun intended - in reading both these books. Most of these methods are arcane. It just seems that people in value investing circles like to hype these book up just because Buffett got his start by reading these books. Under Munger things have turned -

> A great business at a fair price is superior to a fair business at a great price.

Philip Fisher and Peter Lynch's books are much better read.

That said, as the article says in a bull market when markets are going up it is difficult to know if your value picks are actually great. In bear markets no one wants to touch undervalued companies.

Annie Duke has a great book "Thinking in Bets" where she talks about being a professional poker player.

One of the things she hammers on is that just knowing how much/often you win isn't the important part because you can win despite making dumb choices and lose despite making great choices.

The key thing is being able to make the best decision based on the limited information you have, take the consequences (good or bad), and then reset and do it again. This is relevant in poker, investment, or even our careers and a great ideal to reach for.

I included a small blurb on my 2021 reading list: https://caseysoftware.com/blog/my-reading-list-2021
