No, SBC does not want to hold the price. A rising tide floats all boats, so there would be absolutely no reason for that kind of price manipulation.
TRADERS are the ones that manipulate the price, by the way they buy/sell.
There are BILLIONS of shares that are very profitable available right now, and people are selling them. All you have to do is look at the chart - price drops follow 'red' trades, which means shares sold at market.
