$XIAOMI-W(01810.HK)Last Friday, I started building a position at 57.5, but sold a bit early on Monday at 58.2, doing two days of day trading. Starting Wednesday, I firmly bought bearish positions. Why? The logic is simple: there is still nearly half a month until the earnings report is released, and at this position, the arbitrage space for institutions is too small. 58.75 was the peak in July, especially with yesterday's grinding market, allowing some friends holding bearish positions to make a small profit and leave in the afternoon. The so-called end-of-day support lift was just a trick to make retail investors see the price stabilize at 58. This morning, the familiar taste of 58.75 bidding, followed by a plunge with the Hang Seng after the opening, finally reaping the bearish positions that were laid out for two days. Patient investors don't care about bull markets; they can always make money. Compared to the joy of taking profits, what makes me happier is my accuracy in grasping trends.
