- Of course. *Anyone* can sometimes outperform the market. It just means
- that a particular "sample" or market was not representative of the whole. Most
- samples are not representative of the whole, buy many unrepresentative
- samples are, as well as "large" samples.

- Both are probably true. How can both be true? It depends upon what
- assumptions you make about the flow of information. Premise (b) assumes
- that complete information eventually shows up in the market price of
- a security. Premise (a) acknowledges that the stock price doesn't
- instantly reflect the information change.
-
- Through market mechanisms, (b) is probably more accurate, but as an individual
- you probably could place yourself where you would have quicker access to
- certain information. For example, you could hang out where "insiders"
- report their anticipated trading activity. This is the legal way to know
- as least as soon as anyone that a particular insider was intending to make
- a particular transaction.
-
- However, if *you* use public sources of information, then you are no better
- off than anyone else who has access to those same sources.
