People are sending each other messages via trading the small amounts. There's a traders code I had posted , ages ago about the small trades & odd lots.
All in all, it's people positioning themselves. Not morally right.
That's why one has to wonder why brokerage houses allow such trading.
Obviously the brokers make money all the way around at the expense of the small people again.
It doesn't protect the investors or the company at all, just allows the few to control the rest. Also helps to create the fear & greed swings in the market.
