It's interesting to note that several long time posters/holders of shares in EXACT have liquidated their holdings and/or hold very little of the stock at present.
Mr. "Pro" Mushkin comes to mind ( who was wildly off-base in his persistent claims for a much quicker timeline than has occurred with EXAS ) not too mention our beloved stockbroker from Wisconsin, Kirky... who still dabbles a bit in the options; selling puts, buying calls, etc.
People seem to think that they can get back in "easily" but that is not always the case... especially if you are conditioned to only buy on weakness...and have difficulty buying into strength and a big run up.
The fundamental case is very much intact at EXAS. Probably getting better by the day.
