Global Market: Japan's Nikkei rebounds as bargain buying lifts stocks after sharp weekly selloff

Japan's Nikkei share average advanced on Tuesday, recovering from last week's steep slide. Investors bought beaten-down stocks after a market holiday, boosting the index. Global sentiment remained cautious due to rising oil prices and inflation concerns. Focus now shifts to upcoming second-quarter earnings from major U.S. technology firms. Analysts noted the gains reflected a technical rebound ahead of key corporate results.
