DIA Dividend Capture–close out

My DIA dividend capture position was assigned last night as expected, for a net profit of $0.27 per share.  Since my DIA position was called before the dividend was distributed I won’t actually get the dividend (which I am estimating to be $0.25), but my net profit is slightly more with considerably less risk than just buying DIA and holding to ex-dividend.   The image below includes today’s open interest on the DIA options as the far right column.  The Feb 99 calls went from an open interest of around 2400 to 38 overnight, so about 98.5% of the open calls were assigned.  The options up through the 102 strike were mostly cleared out.
