All the sales you see on the yahoo site, are buys NOT sells. They do this crap on purpose and the buy are reflected on their stock options after the hedge funds finish shorting for the exec clients, this happens ALL the time. If you look at most buys they make no sense where they are and where the stock goes, follow the money. E.g, most apple execs were unloading over the summer and the sales just were marked and now they are reflected and they actually went through at lower five hundreds. At the end of the year they are added to the options and will probably won't be relected as sells until next year.
