Does doing your “research”/“homework” on stocks make any sense?
In fact markets are not efficient and participants are not rational. That is why we have booms and busts in markets. Emotions and psychology play a role when investors and/or traders make decisions, sometimes causing them to behave in unpredictable or irrational ways. That is why stocks can be undervalued or overvalued compared to their true value.  Also, different market participants may put a different true value on a stock (depending on their methods of analysis and the information they use to base their analysis on). This is why there are always many opportunities to profit (or lose your money) in liquid markets. Doing your research, homework, or analysis can be related to fundamental analysis, technical analysis, or a combination of the two. For example, you could use fundamental analysis to determine what to buy and then use technical analysis to determine when to buy. To me, doing your homework means to get yourself educated, to have a plan, to do your analysis (both FA and TA), to invest or trade according to your plan and to have a risk management strategy in place. Most people are too lazy to do their homework so will pay someone else to do it for them or they will just speculate (on the latest hot tip) and lose most of their money.
