The tide being the broad market - when the market sells across the board, only few get spared. For stocks that have been in a down trend, they stand even less chance. Today ZNGA took it on the chin and went way below the text book support. I dumped half of my holding today, holding the other half. Fundamentally I still like the company, and I know it's not going straight down to 0. This is dangerous thinking. But let me put it in a different light: I did my part in selling half in fear of it going lower, instead of hoping that it will bounce back. That should neutralize the thought process.
