I'm not advocating that anyone act on this, but a couple of things occur to me.
First, PTSC did some buying last week.
Second, I suspect that PTSC bought all they could (as I recall the SEC regs set limits on the number of shares a company can buy back per month).
Third, assuming the aforementioned SEC regs pertain to calendar month, tomorrow starts a new month (BTW, Happy New Years to all Gov't employees and Gov't contractor employees - new Gov't FY, new funding!).
Fourth, I would think that, if PTSC were so inclined, they would "top off the tank" tomorrow, buying all they can up to the monthly limit ASAP.
Fifth, per SEC regs, companies cannot trade on their own stock in the first hour of trading (nor in the last half hour).
I'll be glued to realtime at 10:30 ET!
Act on these assumptions/thoughts at your own risk....
