a lesson for you. shorts are hedged w/ options so they don't lose when the price goes up. they buy the options cheap when they're way otm. or they're institutional longs using a short as a hedge. i've made money on a short and later after the pps has bounced back, i've sold my hedge for a profit too. i make money on the ups and downs, just not the downs.
and as far as buybacks, ovt needs to do them to offset all the eps dilution from execs exercising options. they tend to buyback right b4 the price falls, last time they bought around 17 b4 it fell to 4. i was short from 26 all the way down to 4 btw. you'd think they'd have bought at 4 like me.
