PPBL & NVAE looks to be benefiting from the new short sell rules that can give it a boost to higher prices:
In 3-2 Vote, WASHINGTON—The Securities and Exchange Commission narrowly approved curbs on short selling, addressing what some consider a cause of the 2008 financial crisis despite criticism that there was no evidence to support the move.
Basically, the new rules puts added restriction on how short sellers manipulate normal market activity – a win win for investors and a definite win for PPBL & NVAE
