Your post covers the reasons I'm not too fond of or follow CHARTS. Tecnical anaysis my foot. Either your in a good investment going somewhere or not. Thats what good DD can tell one. Charts may be a tool, but only one tool. To rely on CHARTS as if they are some kind of crystal ball is foolish.
True one can trade in and out of a stock and increase profit. Does not work every time, does require some luck. Should one be OUT at the time good or great news comes out, which a chart cannot forcast, you lose and will have to choose to chase it or find another one. Thats why smarter traders maintain a core position and trade , is at all, with a smaller amount on a GOOD stock.
CLSN has a lot going for it for many months to come. PERIOD
