Earlier quoted context omitted.
The typical investor cannot get above average results - the market as a whole is the sum total of everyone trying to beat the market. People aren't as special as they think they are. Investment strategies are littered with the ruined portfolios of folks trying to "beat the market".
Please stop, if you don't want to try, it doesn't mean it is not possible... the truth is that the market efficient hypothesis is not valid and there are plenty examples of people beating the market consistently
Efficient market hypothesis has nothing to do with my opinions here. Whether or not it's possible to beat the market has nothing to do with it either. It's simple averaging - I expect than if I pick individual stocks, I'll get an average result for stock pickers as a group, and that average result is the same as the market as a whole.
Want to know my investment strategy? It's taking every dollar from working that's in excess of my expense budget, immediately putting it long a total stock market index, and sitting on it for about two decades. I don't look at the news, I barely look at the index price, and I'll continue doing this if I lose half my money over the next year. I'll get as good of an expected return, except paying less money in fees and leaving my deferred capital gains invested.
