Unless you only had $200 worth of shares to sell, don't fret it. Volume is nothing. It's someone buying a few shares to pump up the price. Spend $200, increase your account balance by $2,000. It happens all the time on stinky pinkies.
Competing is intense among humans, and within a group, selfish individuals always win. But in contests between groups, groups of altruists always beat groups of selfish individuals.
