In what is usually the quiet before earnings season begins, all stocks were whipped around last week by the drama in Washington over the financial-sector bailout.
So I’d be careful reading too much into the 26 percent decline in the stock price of Omega Flex Inc. Its shares closed at $22.95 on Friday. The Exton-based maker of flexible metal hose did not issue any press releases last week.
The biggest gainer among local stocks was Nobel Learning Communities Inc., the West Chester operator of private schools. Shares rose 25 percent to close Friday at $15.93. It received an unsolicited $17 per share offer from Knowledge Learning Corp. , of Portland, Ore.
