This year's investments by the end of the year actually ended up losing the money previously earned, mainly due to the US-China trade war. The US blacklisted more than a dozen companies, including Wuxi Apptec that I bought. Buying at 138, selling at 125, cutting losses directly after dropping to 125, lost over 5,000, had to run. If I hadn't run fast, I would have lost tens of thousands by now. Despite having a good roe and being the third heaviest stock held by foreign investors, it still couldn't withstand sudden political situations - speechless! However, the purchase of Hangzhou Hikvision Digital Technology was still fine, although also on the US blacklist, the proportion of foreign holdings is not significant, so there was a small profit. Therefore, a good stock and company, in addition to having a promising industry outlook, unique technology, high gross margin, high net margin, low debt ratio, political factors in specific backgrounds also need to be considered!
