There's also the argument for diversification - investors holding large fractions of their portfolio in one security expose themselves to the operational risks of the company. By holding a broad variety of stocks, you'd expect their "lumps and bumps" to even out on average so you are only exposed to the overall market risk (i.e. hold airline stocks? Offset that with some oil stocks. And those with solar. etc.).
