Share Washingnormal costs to bring a pump crew on to wash a stock while something is sold off such as warrants will cost the company that has hired the pump crew aprox 20% of total cash taken in by the company. and total volumes washed by the pump crew will be aprox 5 times the number of shares being sold off. Once the selloff is complete the trading volumes will return to normal. Once the pump here is over the float will be 53% larger, a much larger float to borrow from for the shorters Can you imagin the size of the wash job needed in September?
