Closing Bell: Hertz to Split in Two; Yellen, Crude Buoy Market

U.S. stocks ended Monday around session highs even as Fed Chair Janet Yellen remained vague on the central bank's rate-hike plans. Crude also helped fuel gains after spiking more than two percent to close near the $50 a barrel mark. The U.S. is still on track for further rate hikes, according to Yellen who did not give a timeframe though said further gradual moves would 'probably' be appropriate. Yellen also noted the Fed does not rely on a single data point such as the weak May jobs report to determine policy. Hertz (HTZ) - Get Report climbed after making official a plan to separate its equipment rental unit from its core car rental business. Hertz's board approved the move which will take effect June 30. Morgan Stanley has named Lowe's (LOW) - Get Report as one of its top investment ideas. The firm has an OVERWEIGHT rating. TheStreet's Keris Lahiff has details from Wall Street.
