IMO it's decision time for the holder of the bullish call spread given the stock price movement. Exit with profit soon or hold till expiration and hope for a close above $13 by then. But then the incremental profit in the best case scenario compared to taking profits now is 0.50 or so. If he is long the underlying, then he can leg out of the call side against the upside risk of positive news in 9 days. However, option prices suggest no news coming any time soon. I think the high prob case is that profit is taken on options before expiration.
