Twitter on Sale

Bought 60 shares of Twitter (TWTR) for $16.11 a share today around 10:30am and she closed at $16.31 a share. Something I heard on CNBC through satellite radio yesterday about how the share had fallen about 12% in the day and all I could think was that Twitter is on sale. Why not test out my theory? Unfortunately I need about $99,000 more to make any amount of decent money in the trade for the day, which would have come out to a profit of about $1,200 if I sold it before the bell rang. With what I put in, I would have made $12 had I sold it before the bell rang, not even enough to cover the $13.90 in total commission to buy and sell. Anyway, is a curious exploit I'm enjoying, if only for the experience.
