Is The Rally In Bank Stocks Over?

But the party may have come to an end, thanks to Wall Street analysts.

According to a Bloomberg report, JPMorgan and Citigroup Inc C have seen their stocks slapped with more downgrades than upgrades by a margin of nearly two to one since the 2016 presidential election. This also marks a deterioration from the prior three months when the downgrade to upgrade ratio was 1.5.

Part of analysts' pessimistic view has to do with not only elevated valuations but the fact that many banks' implied cost of equity or expected long-term return stands below 10 percent. Citigroup's banking analyst Keith Horowitz commented in a research note last week that this is a level that is typically associated with negative share returns over the next six months.

Not all of Wall Street is bearish, and there is certainly another side of the story. For example, CLSA's bank analyst Mike Mayo thinks bank stocks could gain another 50 percent over the next three years.
