How it works in my head:
Shorts borrow and sell shares, making the price go down in lack of new demand.
Shorts cover and buy at lower prices and do it all over again.
When demand is high, price goes up and shorts cover or double up to keep price down or within a range.
Anavex at this point, if shorts cover and price keeps going up, sells a few shares to cover Misslings haircuts, and lack of skills.
Just one of the infinite scenarios, but take away.
ANAVEX SELLS SHARES TO COVER FOR MISSLINGS HAIRCUTS!!!!
