Historical technology stock super large IPO return differentiation: SpaceX's' front window 'is weak, not necessarily' IPO will draw water ' According to BlockBeats news, on June 11th, according to public data statistics, the earnings performance of the Nasdaq ETF (QQQ) in the four trading days before and after the IPO of large technology companies, as well as in the 20 trading days after listing, was not stable and showed obvious differentiation characteristics overall. In different cases, there are significant differences in the trend before and after the IPO window period: Facebook, Snowflake, Airbnb, Coinbase, and others mostly recorded positive returns within 20 days after listing, while Uber, some stages of Alibaba, Arm, and others showed weaker or more volatile performance. Among them, SpaceX's current simulated IPO window data shows that the cumulative return in the first 4 days is about -6.3%, showing a significant downward shift, weaker than some historical samples, and more like a catalyst for deleveraging crowded positions, rather than the rule of "IPO will inevitably drain". Analysis suggests that this type of statistics is closer to a comparison of the distribution of emotions and financial behavior, rather than a fixed pattern. There is no linear pattern in the market where the IPO window is bound to rise, and different companies are significantly differentiated under the influence of valuation, market environment, and liquidity cycles.
