Pension funds manage large sums of money - decent chunks go into indexes but they also have strong reasons to buy stocks.
For example, many funds are based on (i.e. need in order to meet their obligations) ~7% annualised returns. They should and would be in bonds (super 'low risk') if the returns there weren't so pathetic due to prolonged super-low interest rates - the 2008 recovery was made possible by screwing over savers (and in turn pension funds). They have been having to chase equities and indexes can't reliably return the 7%+ they need. Of course, they could lower their returns expectations but that would mean contributions need to increase or benefits need to be cut - neither of which goes down well and becomes a political problem with voters.
In short, they are damned if they do and damned if they don't
