### Aww, c'mon, you are using this argumentation against
short-sellers? There is large body of research showing that
short-selling and speculation reduce price variability, smooth out
supply shocks and lead to more efficient allocation of resources

Seriously, railing against short-sellers is for me a bad diagnostic
factor, somehow didn't expect it from you.
