Whats up with Berger Paints?

This chart is very strange. At 1:30 pm yesterday, the stock popped up, and has since being going up straight on volumes that are much higher than it usually trades. Is there some insider info out there? Is this company getting sold or something? If some fund house has suddenly become interested in this stock and is buying it at whatever price, the traders at that fund should be fired. Running up a stock 25% is no way to buy the stock. If I find out who the fund house is that is buying the stock, I will never ever buy a fund from that company.
