Up or down, prices changes on such very thin volume are pretty much meaningless. Maybe it's Friday anticipation again for news on Monday. Maybe some are recognizing that the stock is oversold. Maybe it's foreign buyers front running news of a deal of some sort. Maybe it's players trying to push the price up for a big dump.
Anything is possilbe. Hardly worth questioning, IMO, at least until we have sustained volume of very much higher levels.
