With world stocks up more than 10  percent since the start of the year, it must be tempting for investors to cash in their gains before the quarter-end/fiscal year-end. Or is it really?

JP Morgan, which analysed equity buying of institutional investors including pension funds, insurance companies and investment funds in the United States, euro zone, Japan and the UK, finds that there is no empirical evidence of quarterly rebalancing by pension funds or insurance companies.

Below are the charts showing their findings on the amount of equity buying as a share of equity holdings in each quarter against the difference between equity return and the return on total assets. If pension funds and insurance companies do not rebalance at all, the amount of equity buying should be unaffected by the relative return of equities against total assets. And this is the result they found in Chart 1.

 

The regression line is horizontal suggesting no impact from returns to equity purchases.

In the case of investment funds however, they tended to rebalance when equities are doing badly.
