The Yomiuri Shimbun began publishing the Yomiuri Stock Index (Yomiuri 333) on Monday. The closing price on the first day was 35,507.74, a fall of 155.90 points from Friday.

The proportion of stocks that fell in price on the Tokyo Stock Exchange’s Prime Market, where the majority of the 333 stocks that make up the Yomiuri 333 are listed, was nearly 70% on Monday.

This trend was due to a lingering sense of caution about the tariff policy of the administration of U.S. President Donald Trump.

The Yomiuri 333 is a stock price index that indicates trends in the Japanese stock market. The index incorporates the stocks of 333 Japanese companies with equal weighting.

The index value is calculated once a day on weekdays and published in the evening on the Yomiuri Shimbun Online website and elsewhere. The calculation is entrusted to Nomura Fiduciary Research & Consulting Co.

The stock index was shown on the day on a street display of IwaiCosmo Securities Co. in Tokyo’s Kayabacho district.
