One other positive I'd like to point out is that recently price has been rising on strong volume, and when price goes down it's on low volume -- kind of like a slow leak or trickle. I'd attribute the "leak" to non-executive level employees excercising some in-the-money options. For some it's hard to resist the $5000 profit in hand even though there's, say, a 50% chance the stock could be many times higher in a year (1 bird in hand is apparently worth more than 10 in the bush). I suppose it's probably rational to sell a little now if you work there or at Zenith and have no other savings. So I try to ignore those down days with low volume.
When volume picks up, and price moves higher, though, that gets me excited! Hopefully they're informed buyers and not just some covering short seller scumbag!
