Agile is not something a small investor can win at. You can win by reading the 10k and such and then following what is happening in the real world and thus predict what will happen. You should be able to make a nice income doing this full time, but it won't be get rich, and probably won't be even tech levels. Note that I said full time. You will follow many companies and conclude the market is right and thus not do better, while what you need is the one where you can figure out in advance the company will do good/bad before the market does and thus buy/sell in advance.

Peter Lynch famously (he was then manager of the world's largest fund) got out of Gap when he noticed his daughters didn't buy anything there for school and that was his clue that they wouldn't do well next quarter. Gap as had ups and downs since. This is the type of research you will be doing all the time, trying to find a evidence of a company that will disappoint before anyone else knows. This is hard hard hard, and is always a matter of luck. Remember by the time it is public the large players already know and have acted (that is they get alerts the instant it becomes public and are first in line to act on it, technically you get the information at the same time and can act as fast but in practice you will not)
