I kind of doubt that an institution is buying a penny stock. They have to justify it to the fund management and their holders. My guess is a private investor with deep pockets. There is a rich mans club and word gets around. Someone that buys a couple of million shares would only fork over less then $50,000 and to them thats bubble gum money. The Mutual funds usually have a minimum of $5 share price, some as low as $3, however there are hedge funds that will invest a few thousand dollars in pennies. Its like a piss away fund and only represents about 1 to 2% of the holdings.
