I am a self-taught active day trader. Usually in by 10 and out by 3 most days on a wide range of equities. I believe one should never be afraid to take a profit, no matter how small that profit may be and that holding stocks after the close of a trading day, leaves one very vulnerable and that's not a position I ever want to be in. I don't over analyze a stock, the bottom line for me is a stocks moving day average (the larger the better) and how can I leverage that average to my advantage. My methodology goes completely against the grain of the flow of the market. When the market goes down it has absolutely no effect on me whatsoever, as I have no positions that can ever be affected, except that it presents buying opportunities for the next uptrend. I completely protect every position with stop limit orders and as far as I'm concerned it is the only way to protect yourself.
