Abstract: |
The interplay of delegated portfolio management and asset management ownership
generates a double agency problem that may result on trading to support
security prices. We test this hypothesis analyzing the trading patterns of
mutual funds a¢ liated with banks with the stocks of their controlling banks.
We show that affiliated mutual funds tend to increase the holdings of the
parent bank stock following a large drop in the stock price of the bank.
Further, we provide evidence that these patterns of trading are not consistent
with portfolio rebalancing into the banking sector, contrarian trading or
timing skills. We also provide evidence that the patterns of trading are not
information-driven. This leads us to conclude that affiliated mutual funds
follow this strategy to support the price of the parent bank. |
