Quote from dbphoenix:
All of this sounds good, but it's manufactured out of air. MAs cannot represent "mean value" unless everyone agrees on what that mean value is (and if they could, only an idiot would have bought at a higher price, and only a fool would have sold at a lower price). And since there are a near-infinite number of MAs that can be used, it is not possible to find that "mean value" through MAs alone.
Taking this road means trying to apply the same nonsense to TA that is applied to FA, i.e., that companies have a generally-agreed-upon fair value (FA tends not to distinguish between the company and the company's stock; in fact, it often ignores the stock price altogether). Stocks don't have a generally-agreed-upon fair value either. If they did, they'd move only occasionally and sporadically, perhaps only once every quarter.
Those traders or investors who have some opinion on what a stock is "worth" are unlikely to agree on that value. Therefore, it's irrelevant. Those traders or investors who have no idea what a stock is worth beyond the price at which it is being traded understand that every participant has his own ideas on what that value is and couldn't care less as to what those ideas are. Rather they note at what level the most people paid a given price and look to see what those people do when price reaches that level again. Having some notion of whether those participants (the market) are right or wrong in their behavior is not conducive to profits.
