I tend to disagree, which may be because our definitions of "market timing" differ. The times I plan to sell largely revolve around the times when the reasons I bought a stock in the first place are no longer valid. This largely has to do with the fundamental characteristics of a stock. To me, market timing usually revolved around trying to predict when stock/market would take a downturn and to sell beforehand. I don't really care when the stock will take a downturn, I care if a company has fundamentally changed from the time I bought it, no longer making it the same investment (ie: took on a crapload of debt, bought a lot of companies it knows nothing about, etc.). Seeker, I think I can beat most professional traders. Most people can. It's called an index fund.
