> It's likely to be a "picking up pennies in front of a steamroller" type trade. What does that mean?

There are trades where you can make a small profit regularly, but on bad days you take huge losses. The huge losses outweigh all the potential profits by a large margin. Just like picking up pennies is a small gain while risking death to do so

Traders who engage in such behavior are also humorously said to "eat like chickens, shit like elephants"

There are all sorts of interesting facts you can pull out of this, like how if you missed the top 10 best days in the market from 1999-2019, your return was cut in half. If you missed the top 20 best days, you actually lost money: https://www.fool.com/investing/2019/04/11/what-happens-when-... Basically never mistake annualized return over a long period of time for your expected return in a given year (or day, etc).…

Ah yes, real estate, the classic example of something "growing consistently with low variance over a long period of time", is akin to "picking up pennies in front of a steamroller".

Nah, actually, I think that growing consistently with low variance over a long period of time means that the asset is objectively a good buy...

very true but we have no other advice that works for the upwards mobility of a large population

A really interesting thing happened in March 2020. The market crashed and we all remember how gloomy everything looked. Needless to say, some businesses were going to be directly affected by Covid (eg: travel, hospitality) and their stocks went down as much as 80%. But it also became clear that many stocks were just collateral damage (eg: most of the tech stocks), and that they were going to recover more quickly than others. I bought all the tech stocks I could and things worked out great. If anything, I gave myself too much time to execute on this strategy - as a way to protect against the market tanking even further, I decided to dollar-cost average and make my investments over a 6-week period between mid March and end of April. As is obvious in hindsight, the mid-March cohort outperformed the late April cohort by a wide margin. Writing about this in April 2021 doesn't seem so surprising, but I can tell you that in April 2020 I was shocked how fast the market was improving even though the global news only kept getting worse and worse. I am close with many people who run their own businesses, and many of them had their worst weeks in April. I guess the market was recovering following the same rationale that I used, so I shouldn't be too surprised about its behavior, but it was still interesting considering how my risk profile is so different from the majority of other people.

Would I recommend timing the market? Most of the time, no. But a lot of people talk about the impact of the 10 best or worst days in the last 20 years, and I would say those "insane periods" do exhibit somewhat recognizable patterns that makes it possible to identify them and take advantage of.

I'm going to add that I did a rudimentary an analysis of the S&P 500 because everyone seems to be throwing their money into passive S&P500 low vehicle investments. I looked at every hold period since inception from 1 year holds / returns up to 40 year hold and returns. Timing is crucial for good returns - depending on when you put in and take out your money the returns can be negative (even in cases where you hold up…

> depending on when you put in and take out your money the returns can be negative (even in cases where you hold up to 15 years) Sorry, but unless you're talking about truly black swan circumstances like the Great Depression or the 2008 crash, I don't believe for a second that, over a 15 year timespan, holding the S&P will result in negative returns frequently enough that a typical investor has to concern themselves…

go look at the investments into the market 98 early 2000s in the market and how they underperformed for about a decade. (look at the NYT visualization you were commenting on). Adjust it for inflation.

My point is that investing at the peak of the market will not generate returns unless you unload before the market goes down. Now who knows if the equity markets are going to get clipped (or rather when) ... timing is fickle.

Also, selling on good years makes your performance exceptionally good.

I guess TL; DR. Either sell in the good years around nowish if you've generated a return as equity markets are frothy or be prepared to hold a long time to generate a return [statement for S&P index not individual stocks] assuming the future follows some of the past patterns (sample size is small though to be fair).

I think a lot of newcomers to stock investing in the past year have been given the wrong ideas about the stock market. When all of the headlines are about GameStop and Nokia and AMC and some kid who made it lost a lot of money on RobinHood, the stock market can feel like a place for gambling. Now that cryptocurrency prices are listed right next to stock prices, many people don’t even understand that stocks are owners…

The problem is options/derivatives trading. That is straight up gambling. There’s a meta market where you bet on the behavior of the market...

When gambling, the house "always wins" over time. With options trading, that's not always the case. Anyone with a gambling addiction would be far better off doing options trading - their chances are much better.

I agree with this except I think if you know a stock or two is good, diversification is unnecessary. I’ve only had two stocks in my portfolio for the last ten years.

I am happy for you that your 2 picks have been good. But most likely you have been lucky (maybe you picked AMZN, TSLA). Modern portfolio theory states that diversification gets you closer to better returns on average with lower risk. [1] https://en.wikipedia.org/wiki/Modern_portfolio_theory#Divers...

I would say people who picked amzn and Tesla are lucky. The jury is out on amzn. Bezos did something no public company ever did to the extent he did. He put customers before profits in an extreme way. Then, he built another multi billion dollar unit from scratch with AWS. So far, it’s worked out but the PE makes it speculative nonetheless. But the gap is quickly closing making it an investment grade issue. I don’t know so I leave it alone knowing I’ll regret it one day. That’s fine. I stay away unless I’m 95% sure. I would say s&p 500 represents 100% certainty overtime, because if it wasn’t, life as we know it wouldn’t be the same anyway we’d have bigger problems. Tesla is just a dumb gamble. There’s no justification at all for its price and history shows us what can happen with auto stocks.

Ultimately it's about risk (permanent loss) control, and if you've done the research into those couple of companies, have high confidence in their continued success, and are diligent in continuing to update your views, then it sounds like you're managing risk well. There's always the chance of unknown, idiosyncratic, and potentially disruptive factors though--from a financial planning and risk management perspective,…

Yes there’s a bigger chance of a black swan event. You have to answer for yourself if the extra point or two of cagr is worth it.

Same for the lottery, if you just know which numbers are good then you only have to buy one or two tickets ever and you're set for life.

This is a bad analogy. The stock market is not a lottery. It’s a place to buy and sell shares of a company. Most people treat it like a lottery and that can serve you rather than hurt you if you know what you’re doing.

The point of the trivia is arguing against trying to time the market. Lots of people predict crashes are coming, so shift money from equities to cash or bonds. Unless you can time it perfectly (you can't), it is better to hold because you don't know when the best or worst days are.

It’s such a fundamental contradiction you see it everywhere. The quote “buy low, sell high” says we should time the market. Even the classic “percentage of bonds to stocks should be your age” requires us to time the market. And if you just buy stock when you happen to have spare cash, that too is “timing the market.”

I would argue that the percentage of bonds should be your age is not timing the market in any meaningful sense of that phrase. (I also think that's too conservative an asset-allocation, but in any case "make a periodic rebalancing trade according to this preset formula" is the opposite of "time the market".)
