Italy’s UniCredit said on Wednesday it has raised its potential stake in Commerzbank to 28% using further derivatives, as markets watch whether it will take the leap with a buyout of the German lender.

Italy’s second-largest bank said 9.5% of its holding in Commerzbank is through a direct stake and around 18.5% is obtained through derivative instruments.

UniCredit has applied to the European Central Bank for permission to acquire a stake of up to 29.9% in the German bank and simultaneously has a bid in for Italian peer Banco BPM.

CNBC has reached out to Commerzbank for comment.

Financial advisors will soon — and for the first time — hold more of their clients’ assets in exchange-traded funds than in mutual funds, according to a new report by Cerulli Associates.

Nearly all advisors use mutual funds and ETFs — about 94% and 90% of them, respectively, Cerulli said in a report issued Friday.

However, advisors estimate that a larger share of client assets (25.4%) will be invested in ETFs in 2026 relative to the share of client assets in mutual funds (24%), according to Cerulli.

If that happens, ETFs would be the “most heavily allocated product vehicle for wealth managers,” beating out individual stocks and bonds, cash accounts, annuities and other types of investments, according to Cerulli.

Currently, mutual funds account for 28.7% of client assets and ETFs, 21.6%, it said.

ETFs and mutual funds are similar. They’re essentially a legal structure that allows investors to diversify their assets across many different securities like stocks and bonds.

But there are key differences that have made ETFs increasingly popular with investors and financial advisors.

ETFs hold roughly $10 trillion of U.S. assets. While that’s about half the roughly $20 trillion in mutual funds, ETFs have steadily eroded mutual funds’ market share since debuting in the early 1990s.

“ETFs have been attractive for investors for a long time,” said Jared Woodard, an investment and ETF strategist at Bank of America Securities. “There are tax advantages, the expenses are a bit lower and people like the liquidity and transparency.”

ETF investors can often sidestep certain tax bills incurred annually by many mutual fund investors.

Specifically, mutual fund managers generate capital gains within the fund when they buy and sell securities. That tax obligation then gets passed along each year to all the fund shareholders.

However, the ETF structure lets most managers trade stocks and bonds without creating a taxable event.

In 2023, 4% of ETFs had capital gains distributions, versus 65% of mutual funds, said Bryan Armour, director of passive strategies research for North America at Morningstar and editor of its ETFInvestor newsletter

“If you’re not paying taxes today, that amount of money is compounding” for the investor, Armour said.

Of course, ETF and mutual fund investors are both subject to capital gains taxes on investment profits when they eventually sell their holding.

Liquidity, transparency and low fees are among the top reasons advisors are opting for ETFs over mutual funds, Cerulli said.

Index ETFs have a 0.44% average expense ratio, half the 0.88% annual fee for index mutual funds, according to Morningstar data. Active ETFs carry a 0.63% average fee, versus 1.02% for actively managed mutual funds, Morningstar data show.

Lower fees and tax efficiency amount to lower overall costs for investors, Armour said.

For one, mutual funds are unlikely to cede their dominance in workplace retirement plans like 401(k) plans, at least any time soon, Armour said. ETFs generally don’t give investors a leg up in retirement accounts since 401(k)s, individual retirement accounts and other accounts are already tax-advantaged.

Additionally, ETFs, unlike mutual funds, are unable to close to new investors, Armour said. This may put investors at a disadvantage in ETFs with niche, concentrated investment strategies, he said. Money managers may not be able to execute the strategy well as the ETF gets more investors, depending on the fund, he said.
