mars, the big DRIV selloff in the fall was driven in part by a widely held perception that SYMC, a major DRIV customer, would be developing its own competing facility for its own software delivery. I don't believe much, if any, of that fear has found justification in the interim. the jump tonight appears to have been caused, in great part, by an upward revision in earnings guidance which, the boards are speculating, may indicate an initial DRIV/MSFT contract is in the offing.
DRIV stock price is driven by speculation and emotion; just look at the chart. I'm in at 35 tonight (first I could catch up to it; I'm not so fast as some of you <g>), wishing for a gap fill (up!) or more in the morning
