RE:Time for another 50$ tradeFirstly, why would you care about someone making small trades like this, unless you're one of the people shorting the stock? If you're hoping to sell your shares wouldn't the rational position be to be happy that the price is rising so you can get a premium?
Secondly, people selling similar small numbers of shares happens as well. Someone sold 500 shares at 9 cents this morning. Everyone's circumstances are different and some people may prefer to trade at much smaller volumes.
