请问HN：如何对SpaceX纳入标准普尔500指数的规则变更表示异议？
标准普尔500指数及其他指数基金正在评估修改股票纳入基金的规则。可能会取消多个规则：
* 交易满12个月
* 盈利至少4个季度
* 至少10%的股票可交易
最终的结果可能是，来自Space、OpenAI和Anthropic的首次公开募股（IPO）将导致其股票被纳入指数基金，从而自动被购买，而市场没有机会设定正确的价格。
基本上，普通的被动投资者和养老金基金在IPO被高估的情况下将承担风险。
退出基金没有意义，因为这会触发资本利得税，因此我们无法通过退出基金合理地反对这一规则。我们可以停止购买，但这对改变的反对信号较慢。
我们能做些什么？给标准普尔写信？给证券交易委员会（SEC）写信？给我们的经纪人/指数基金提供商写信？
还有其他行动可以采取，以避免富人强迫普通人购买他们的投资吗？

S&P500 and other index funds are evaluating changing the rules for including stocks into the fund.
There are multiple rules that might be dropped:
* 12 months of trading
* 4 quarters of profitability
* at least 10% of stocks tradeable<p>The effective result might be that IPOs from Space, OpenAI and Anthropic result in their stocks being added to index funds, and thus automatically bought, without a chance for the market to set the right price.<p>Basically regular passive investors and pension funds would end up holding the bag in case the IPO is overinflated.<p>Exiting the fund makes no sense, as you'd trigger capital gains, so we cannot reasonably vote against this rule by exiting the fund. We can stop buying it, but that is a slow signal against the change.<p>Is there something we can do? Write to S&P? Write to the SEC? Write to our broker/index fund provider?
Are there other actions we can take so we don't go in the direction of rich people forcing regular people to buy their investments?<p>For context: https://fortune.com/2026/06/02/spacex-index-funds-new-listing-rules/
