$XIAOMI-W(01810.HK)$ Xiaomi has been falling in the recent period of time, even if the large buyback is still unable to stop the decline, this is why? Isn't xiaomi's buyback a big deal? No! Xiaomi's buyback efforts are relatively larger than Tencent's. Tencent 5 trillion market value, buyback a day 100 million, Millet only 500 billion market value, buyback is basically 100 million market value every day, buyback strength is not big, but why can't stop it?
