I bought it from the 6,000 yen range, and now 85% of my stock investments are concentrated in softbank group co. Currently, there seems to be no short sell institutions, but there are institutions for buying and selling. I own american stocks arm and NVDA. I believe that softbank group co stocks will aim for 12,000 yen. I am increasing my holdings while taking profits from profitable stocks. I am looking forward to when the investment in OpenAI will become profitable.
