Читать книгу Positional Option Trading - Euan Sinclair - Страница 22

It is difficult to make money in financial markets. The EMH isn't completely true, but it is closer to being correct than to being wrong. If a trader can't accept this, she will see edges in noise and consequently overtrade. Behavioral finance, technical analysis, and fundamental analysis can all be used as high-level organizing principles for finding profitable trades, but each of these needs to be believed only tentatively, and the most robust approach is to look for phenomena that are independently clear. For example, momentum can be discovered through technical analysis but also understood as a behavioral anomaly. The observable phenomenon must come before any particular method.
