This is a great article that explains markets (not just the stock market really) in an easy to understand way. The one thing I believe people should know about the stock market is: There are people with more capital, time, and knowledge than you who will consistently beat you. Picking individual investments is mostly a sucker's game. Buying tech stocks and/or crypto in the last couple of years has been a consistent e…
That right there is the best advice. If you want to get rich quick, you're going to have to make some calculated bets with higher return and thus higher risk. However, if those bets work out and you do become rich, don't fool yourself into thinking you're some kind of super genius that can consistently beat the market.
This can be a hard lesson for people to learn (it took me a long time), because in most aspects of life success is more skill based. With investing, there is more decoupling between action and outcome due to randomness, and you have to always consider you may have made the right choice and lost, or you may have made the wrong choice and won. In the case of the latter, take your winnings and be happy, but don't delude yourself into thinking you made a good play. This is extremely hard, you have to be willing to put your ego aside and realize you actually made a mistake that made you a lot of money.
I think ordinary people with the right knowledge and foresight at the right time can beat the market in the short term. The trick is to be extremely patient until you have a reasonable level of confidence you have an edge in a bet with an asymmetrical return, and then take a position with conviction. I've done this a few times in my life, and the knowledge, timing, and luck all happened to work out for me. I've also had that feeling a few other times where things went south. Luckily for me the winners far exceeded the losers. However, I wouldn't con myself into believing I can consistently generate an edge. I simply made a small number of calculated bets when the stars all aligned for me. It's very possible the stars will never align for me again like that, which is why I've now moved most of my money into ETFs and other safe investments.
One way to spot someone who doesn't know what they're doing with investing and trading, is you never hear about their losses. You never hear about their net gains. You never hear them tell you the story of when they drunkenly made a really stupid leveraged stock pick that just happened to work out from pure luck. No, you hear all about the winners, all about how they knew for sure it would work out for all these reasons. You just see the overflowing ego that gambling has drummed up, rather than the intellectual honestly of someone who has sat back and grappled with the tough question, "did I make all this money because I'm smart, or am I just a dump and lucky ape?"
