Chris - Sorry I could not get back to you. I have been teaching greenies how to sell retail luxury items all week and could only catch the tale end of today. I'll go into that later.
You should not be hitting yourself about BUYING at $4.17. You should be hitting yourself for not selling a portion when the trend reversed.
You know my style. I maintain a core, but I sell my play shares when I smell a short term trend reversal. I buy them back when I see it bounce and turn back up. Only been wrong twice and once was one I held onto when I knew to sell because Britnick came on to announce the permit had been approved and delivered to KRY. My bad.
Most of this BID-ASK volume is fake so don't focus on it too much. Watch how the stock moves regardless of the BID-ASK and you will learn how it reacts. Play that, not the BID-ASK.
