Vida, a Chinese-American billionaire born in the 2000s, has entered the A-share market to buy on the dip! Worth learning from and emulating! Vida, founder of Equation News, posted on Telegram last night: He bought shares of Zhongji Xuchuang, Invesco China Technology ETF, and Tencent last Friday. He also stated that if the panic in A-shares intensifies tomorrow, he will consider buying heavily. His logic is simple: betting on a rebound from oversold conditions. He believes the current A-share market is very similar to the South Korean stock market from late July to mid-August this year: a sharp drop, panic, despair, followed by a rapid rise. But we need to see through his underlying strategy. Zhongji Xuchuang, China Technology ETF, Tencent. He's not buying traditional value stocks; he's buying the core "high-elasticity sentiment targets" of the A-share market. These tech stocks and computing hardware have suffered the most severe declines recently. The steeper the fall, the stronger the rebound. Essentially, he's betting on a reversal in sentiment after an oversold condition. What does this mean for ordinary stock investors? Vida's logic is correct: oversold conditions inevitably lead to a rebound. However, he failed to mention two fatal premises: First, he has unlimited funds to withstand further declines, even buying more as the price falls; Second, he's "picking up the corpses of others," profiting from the bloodied losses of retail investors. While big players enter the market to pick up these losses, retail investors must also be quick to enter and exit, lowering their expectations. If you see the A-shares market open lower tomorrow and want to follow the big players and rush in to buy the dip, ask yourself first: If it continues to fall tomorrow and the day after, can you, like him, muster the confidence to invest heavily? The money from oversold rebounds is earned by big players through their massive capital and emotional control. Ordinary people who blindly follow the crowd often just become cannon fodder in this rebound.
