People can still be buying security protection with the stock at 71 or even below. The small float and restrictions on sale of stock meant it was easy to push the stock up. With more stock out there now and restrictions lifted, it will be harder.
It is also easy to push a stock lower, especially when buyers step aside as lockup expires, as they did today. This has fed on itself to an extent, as fear of lockup expiration led to selling and then those finally able to sell after lockup expiration saw the falling price and dumped shares. If the market collapses, all bets are off, but if we see the high $60's in the morning, we are likely to see a reversal and a nice bounce back to the mid $70's.
