The Nikkei Average fell by more than ¥800 at one point in the morning on 9 October, but recovered to near its closing level as buybacks emerged in the afternoon session. Reports concerning U.S.-based OpenAI's sales outlook were cited as a factor behind the impact on semiconductor-related stocks.
The Nikkei Stock Average ended trading on 9 October at ¥69,030.92, down ¥11.19 from the previous day. The market moved lower in the morning under the influence of U.S. markets, with selling particularly widespread among semiconductor stocks, but buying returned in the afternoon session. The catalyst was a report in some British media that OpenAI's sales outlook was below market expectations, which prompted increased activity in semiconductor-related stocks.
