Apple trade today

Was anyone lucky enough to hit the Apple trade today. Related to options dating issues, AAPL was down significantly to the mid 77's at 10am. By 3pm it was back up to mid-81's. I'm not a day trader but I had to act like one when I saw this opportunity. This just shows one advantage that a retail investor has. Institutional investors can and do see these anomalies, but if they do anything meaningful for them the size of their trades moves the market. The retail investor can make a normal long trade or take an option position within their investment parameters and not move the market at all. In other words, they get the full spread between their trades.
