How do I manage my portfolio as stock evaluation criteria evolve?
If your criteria has changed but some of your existing holdings don't meet your new criteria you should eventually liquidate them, because they are not part of your new strategy. However, you don't want to just liquidate them right now if they are currently performing quite well (share price currently uptrending).  One way you could handle this is to place a trailing stop loss on the stocks that don't meet your current criteria and let the market take you out when the stocks have stopped up trending.
