The investment universe is divided over the future of banks

Battle lines have been drawn between hedge funds and their mutual fund counterparts.

Their battlefield? The financial sector.

Large-cap mutual fund portfolios carry a 141-basis-point overweight position in financial stocks, relative to their benchmark, making it the group's second-most bullish bet, according to data compiled by Goldman Sachs. Meanwhile, hedge funds have the industry as their most bearish position, with a 438-basis-point underweighting relative to the Russell 3000 Index.

This divergence in outlook gets even more pronounced when you drill down into the banks, long the most influential segment of the financial sector. Banks are the most underweight group out of 71 sectors for hedge funds, Goldman data show. That stands in stark contrast to mutual funds, for which it's the third-most overweight.

That mutual funds are relatively isolated in their preference for bank stocks isn't particularly surprising, given the group's recent history of bucking consensus. While many investors have thrown in the towel on President Donald Trump enacting any sort of bank-friendly major tax or deregulatory policy, mutual funds are staying strong in their conviction.

Nonetheless, if you dig deeper into the positioning war between mutual funds versus hedge funds, there is some semblance of consensus at the single-stock level. Most notably, JPMorgan and Citigroup are among the most popular holdings for both groups of investors.

The two types of funds also agree on tech stocks, with both mutual and hedge funds holding matching 26% overweight positions, making that the most bullish sector for both groups.

In order to compare the two types of funds, Goldman Sachs analyzed the holdings of 803 hedge funds with $1.9 trillion of gross equity positions, as well as 543 mutual funds with $2.0 trillion of assets under management.
