Jim Cramer says this tech stock’s sell-off is an ‘overreaction’

Jim Cramer is no stranger to what causes the constant ups-and-downs that dictate the stock market, and is quick to see an opportunity when it arises. The CNBC pundit told subscribers of his CNBC investing club on Sept. 12 that he thought that the sell-off of shares in Oracle is "overdone and a clear-cut buying opportunity" after the Silicon Valley mainstay reported mixed fiscal first-quarter results the day before. "It's killing me that we can't buy," said Cramer, referring to rules that prevent him from trading stocks he mentions on CNBC.
