Over the past several days I've seen a bunch of trades for 4,900 shares, followed by a trade for 100 shares. They tend to happen when the stock gets knocked down, and afterward, it recovers. Any thoughts on what's going on?
Not only that but some of the trades were done in pairs. For example, 4900 shares sold at 70.91 and 4900 shares bought at 70.98. Seems like there is an inventory of shares ready to be shorted , waiting for the buyer.
