I'm worried about when to start long-term investment in US stocks. The benefits of the new NISA's tax savings measures starting next year are huge, so I don't think it's a good idea to buy stocks with a specific account from now on. However, I also feel like I've missed the timing to buy it, so could Taro give me some advice?

Apart from that, investors are not chasing Buffett, and when Buffett buys, it is because that company has future potential and buys it.

By the time Buffett passed away, people who made money from profit margins would have already sold and not determined profits, and the people holding them should also get dividends if the company's management is going well, so there's no impact.
