The pre-market has turned negative, but there is no need to worry. After all, the Nasdaq 100 index inclusion was announced last Friday after the market closed, even after the post-market trading had ended, with no trading opportunities available outside regular hours. Today, only MUUMUU Securities allowed after-hours trading starting from 10 a.m. Japan time on Monday. While Palantir is popular in Japan, most people buy and sell US stocks through online securities such as SBI, Rakuten, and Matsui, so they cannot purchase during extended hours. Therefore, trading will begin from the regular session on the first day after the index inclusion. Institutions typically only participate in regular trading. Furthermore, due to regulations, there is a need to forcibly purchase a certain number of shares. At least for the time being, I don't think there is much need to worry about downside risks. Let's consider it as the last stand of the short sellers.
