This was likely a computer generated sale that was set off due to the market down turn. If everyone freaked out and sold, as you state, the price would have gone much lower!
I'll assume you didn't buy today because the stock's price never got down to $10.99. At least you got in at a fair price, unlike the individual that came to this board announcing he bought 200k worth of this stock at $11.35 and didn't care if the price went down. If I'm correct in my above assumption, you have already collected at least 1 monthly dividend.
I get over $3k per month from this company in (return) and that's the way you should look at your dividend. View it as a return of equity instead of a dividend and hold for your established price points to reinvest that ROE. If you do that, you'll enjoy the down turns in the stock's price.
