This has been going on since the stock market was invented. The cry goes up .. " WHO'S SELLING ? ". And it's ALWAYS either the Insiders or the Financiers. I mean big blocks steadily. Now it's a flavor of the times .. " It's short selling .. either legally or illegally ". No it is NOT !!!!!!! There may be a little bit though.
If they are dumping to make money. They could wait till next day instead of getting a lot less per share at the end of each day. In other words no need to walk it down.
