> indexers think they should own 10% of your company
i like to believe indexers are not that easily fooled.
broad market indexers (think 2-5k stocks like the russell) normally use an approximation portfolio that holds significantly fewer assets in order to minimize transaction cost. the correlation between a 500-asset portfolio and a 5000-asset portfolio is something like 98%, maybe more. a lot of replication portfolios don't even bother with the underlying nowadays, they just load up on cash settled equity swaps with the dealers and let them deal with the basis.
and narrow market indexers track indices that won't bother including corporates with tiny floats.
