Would you say 30% is a big loss or is that level still reasonable enough to cut out?
A 30% loss would horrify me, but then I probably have a shorter term horizon, and therefore a lower loss tolerance, than most people on this forum.
For anyone who wants to invest from a longer term perspective but isn't willing to hang on to stocks while they plunge south and lose most of their value, you could do worse than study Stan Weinstein's 'SECRETS FOR PROFITING IN BULL AND BEAR MARKETS'.
Stan has an approach that gets you into strongly trending stocks shortly after they begin trending and keeps you in them as long as their trend continues, which could be years in some cases. But the real strength of his strategy is that it steers you clear of a situation where you make big gains but then end up giving it all back to the market. Or worse still, watching your big gain turn into a big loss.
Even if you don't have a big gain, the damage control component of his system ensures that you'll never suffer account-crippling losses.
