TOKYO - With many investors still willing to bet on the artificial intelligence investment boom, the Tokyo stock market's rally that recently pushed the Nikkei index to the 70,000-point mark may continue, with progress in U.S.-Iran talks possibly brightening sentiment regarding broader sectors, analysts say.

The Nikkei jumped nearly 5 percent on June 15, the first trading session after the United States and Iran announced a deal to end hostilities, advancing to just below the 70,000 line and topping the threshold the following day.
