Odd jumps This stock is prone to these type of jumps, about every 2 years there's a big one that's sustained for a bit then jumps back down, and eventually it gets range bound again with spikes every few months.
I love this company as a lottery ticket, been in and out several times, I rarely get the low and never have hit a top, but I've still made bank playing with small amounts 2-5k and I don't get greedy.
Why the jumps, I dunno for sure, maybe it's management bonus clauses that they get share options and the company buys them a bunch of shares, sometimes there's news on developments or new large quantity orders other times I feel a big investor thinks they found the next big thing... either way the stock never has seemed to sustain these and for that it's a short term fun money maker if you pick your spots..
Personally I'll likely wait for the 60-70 cent mark to jump back in jump back out around @ dollar or so... don't try and over analyze this one until something major happens, just buy 10s of thousands of tickets when it drops and wait for that one morning it gets hot and shoots up and cash out, buy a steak dinner and wait and repeat...
