Nasdaq's proposed overhaul of the Nasdaq-100 Index methodology, driven by SpaceX's upcoming IPO, introduces rules that could artificially inflate stock prices and transfer wealth from passive investors to corporate insiders. The core issue centers on two changes: a 'Fast Entry' rule allowing newly listed companies like SpaceX (targeting a $1.75 trillion valuation) to join the index within fifteen days, bypassing standard liquidity requirements, and a controversial 5x multiplier for stocks with less than 20% free float. Under this multiplier, even a company with only 5% of its shares freely tradable would see its index weight calculated as if it were 25% float, forcing passive ETFs and funds to buy massive allocations based on artificially inflated valuations.

This creates a dangerous scenario where tens of billions of dollars of price-insensitive capital are legally mandated to aggressively bid for a stock during its most illiquid period, artificially boosting prices before insiders can potentially sell locked-up shares. The rules also incentivize timing lock-up expirations to coincide with quarterly index rebalances, ensuring passive funds are forced to buy even more shares at inflated prices. While the author doesn't accuse SpaceX or Nasdaq of illegality, the structural manipulation inherent in these rules threatens to distort market prices and undermine the integrity of the index for retail investors.
