If a single drop can overturn such a strong trend that has been built up for so long, isn't that a bit hasty?

Pullbacks during an uptrend are very normal. If you want to say the trend structure has reversed, at least it needs to drop below 100,000.

Of course, if you're doing short-term trading, you shouldn't worry about the direction, as there are opportunities for both long and short positions in a 2,000-point swing. As long as you find the right position, you can make a profit no matter what you do; the premise is to strictly manage your defense!
