If so, then he's an idiot. His game after yesterday's close, 47 thousand shares, had no effect on today's trading, nor did his other purchase of 47 thousand shares during the course of the trading day (at above prevailing prices). Seeing these failures, a rational person would not buy 20,000 shares in after hours at so high a premium over the closing price. This will also fail to impress the market.

Like I said, there are sometimes unexplainable abberations in thinly traded issues, and they usually have little meaning.
