This week I was interviewed about my trading philosophy. In the interview, I mentioned how difficult it is to make money daytrading or swingtrading for short-term profits. This is mainly a zero-sum game, I will even say it has negative expectancy due to commissions and slippage. Opposite, long-term investing has a positive expected return, given a diversified portfolio, as long as you have time on your side. Short-term trading has many losers and few winners, while long-term investing has many winners and few losers. Which game do you want to play?
We like to read about the short-term traders making millions, but the statistics lie. I’m pretty sure the median short-term trader loses money, while the median long-term trader has a positive return. Averages are deceiving. As Nassim Taleb writes:
Never cross a river that is on average four feet deep.
Nassim Taleb likes to call this scalable vs. non-scalable profession, something I wrote about several months ago.
However, trading is of course doable, we at RationalThinking have been moderately successful for two decades. Please check out The Robust Trader for a detailed article about what you need to succeed in trading.
