Hindsight is 20/20 sir, even though the doji star signified a potential reversal there was also the pending possibility of an 8k any time between last friday and march 1st that could initiate another huge run, flipping this is very risky unless you have an army of traders to push the price up or down like moneyrunners
It's very hard to sell millions of shares and then buy back lower without driving the PPS back higher...it's a gamble that may or may not pay off in the end. It could be profitable to hold a core and flip a percentage of your shares, but liquidating an entire position in ATRN is very risky...we have seen that it can go back up almost as fast as it falls.
