Why I don't trade stocks and (probably) neither should you
Well put.I used to work for financial traders. I even used to have a brightly colored coat and a trading floor badge, back when that mattered. I've read The Economist for 20 years. Despite understanding the financial markets better than most, I never trade individual stocks. Everything's in low-load funds; I look at the allocations every year or two.Why? Because I know what I'm up against. I have friends who are still in the industry, deploying vast computational and financial resources to make money. For any given stock, there are people who follow the company and its markets more closely than I ever will. And all of those people regularly fuck up, losing millions. I'm not interested in stepping to that.And there's another big reason: it's a giant minefield of cognitive biases and emotional weirdness. For example, you can think of the market as a random walk with an upward bias. Year on year, you're generally up. But day by day, you're can be down nearly as often as up. Because of loss aversion [1], you'll feel the losses more strongly than the gains. Looking at your stocks every day will at least add to your stress levels, and maybe your decisions will get thrown off. (This example is taken from the excellent Fooled by Randomness [2], which I recommend to anybody who wants to trade, or even understand the financial markets.)I focus my energies on areas where I have a an actual advantage, and I encourage others to do the same.[1] http://en.wikipedia.org/wiki/Loss_aversion[2] http://www.amazon.com/Fooled-Randomness-Hidden-Chance-Market...
