Not quite, because stocks tend to go up.
What really is hard is making more profit than just holding stocks would. Because that takes actual new ideas.
- grenoire 7y agoStocks do not tend to go up, that would imply a greater than 0 return average for series. We instead get mean blur and skewness (which is actually often to the left). The aggregate of the traded stocks, i.e. the market, goes up on average. That's why you make money by holding diversified portfolios.
