Tokyo stocks plunge in morning trading on June 20 as tech shares tumble

Tokyo stocks opened the trading session on June 20 in negative territory, with the Nikkei index falling more than 3% in the morning. The main triggers were profit-taking by investors after the prior session's gains and a sharp decline in technology shares, tracking falls in their US counterparts.

Meanwhile, rising crude oil prices also added pressure across the market, making investors more cautious. Key benchmarks on the Japanese stock exchange posted notable losses during the morning session.
