> Is Snap big enough that indexes tracking the S&P 500 would buy up Snap? With the risk of stating the obvious... index funds tracking the S&P 500 index buy exactly the 500 stocks that form the index, no more no less (modulo some derivatives that are highly correlated with the index). So they will buy Snap whenever S&P decides to include Snap in the S&P 500 index. Snap has already surpassed the minimum necessary market cap (~U$5 billion). There are other criteria, but ultimately the inclusions and exclusions are decided by committee [0]. When they do decide change the index, they announce it well ahead of the date when the change is effective.
