Claro Advisors Inc. increased its Vanguard Mega Cap ETF (MGC) position by 14.0% in the fourth quarter—buying 5,579 additional shares to total 45,428 shares, worth about $11.41 million. The article also notes MGC makes up 1.6% of Claro’s portfolio (14th-largest holding).
Claro Advisors Inc. raised its iShares Core Total USD Bond Market ETF (IUSB) stake by 15.9%—adding 42,038 shares to reach 305,803 shares, valued at about $14.23 million. The report adds that IUSB represents roughly 1.9% of Claro’s portfolio (11th-largest position).

For IUSB, Wells Fargo & Company MN materially increased exposure—raising its IUSB holdings by 2.9% in the fourth quarter by adding 1,331,490 shares. Wells Fargo is reported as owning 47,946,578 IUSB shares worth about $2.23 billion after the purchase.
In Vanguard Mortgage-Backed Securities ETF (VMBS), Focus Partners Wealth acquired a new stake in the fourth quarter valued at about $113,419,000, according to the report’s summary of institutional activity.
Claro Advisors Inc. raised its stake in the Vanguard Mortgage-Backed Securities ETF (VMBS) by 28.5% last quarter, part of a broader push into bond and fixed-income funds. The Boston-based wealth manager also boosted its iShares Core Total USD Bond Market ETF (IUSB) position by 15.9%, adding 42,038 shares to reach 305,803 total shares worth about $14.23 million, according to Ticker Report.
The moves reflect a wider institutional trend. From giant banks to boutique advisors, firms are piling into low-cost bond and mega-cap equity ETFs as a hedge against market uncertainty. Agency mortgage-backed securities — bonds backed by government-linked agencies like Fannie Mae and Freddie Mac — have become a go-to tool for income-focused managers.
Claro Advisors made three notable ETF moves last quarter. It bought 5,579 more shares of the Vanguard Mega Cap ETF (MGC), lifting its total to 45,428 shares worth about $11.41 million. That position now makes up 1.6% of the firm's total portfolio — its 14th-largest holding — according to Ticker Report.
On the bond side, the firm's IUSB increase of 15.9% brought its stake to $14.23 million. IUSB is now Claro's 11th-largest position at roughly 1.9% of its total portfolio. The VMBS stake grew 28.5%, adding meaningful exposure to government-backed mortgage bonds. VMBS carries an expense ratio of just 0.03% — making it one of the cheapest ways to own mortgage debt.
Claro was far from alone. Focus Partners Wealth opened a brand-new VMBS position worth about $113,419,000 last quarter. That nine-figure buy signals strong demand for agency mortgage bonds among larger advisory firms, according to Ticker Report.
Wells Fargo & Company MN went even bigger in IUSB. The bank added 1,331,490 shares of the total bond ETF, pushing its total holdings to 47,946,578 shares worth roughly $2.23 billion. That makes Wells Fargo one of the largest single holders of the fund. Some analysts warn this kind of concentration creates risk — if a giant like Wells Fargo exits quickly, it could create a liquidity crunch in the ETF.
Sound Income Strategies LLC, a Florida-based income-focused firm, made a dramatic shift into MGC last quarter. It boosted its stake by 816% — buying 408 shares to reach a total of 458 shares worth about $116,000. The dollar amount is small, but the percentage jump shows a sharp change in strategy, according to Ticker Report.
MGC holds the largest U.S. companies — names like Apple, Microsoft, and Nvidia. In 2026, less than 5% of active large-blend funds beat their passive peers, according to Morningstar data. That track record is pushing even income-focused boutique firms to swap active stock picking for cheap, broad exposure to blue-chip giants.
The shift into bond ETFs comes as energy-driven inflation keeps rate policy uncertain. Agency MBS funds like VMBS offer a yield above Treasuries with no default risk — because the underlying loans are guaranteed by government-linked agencies. The fund's 0.03% expense ratio makes it nearly free to hold, adding to its appeal for cost-conscious advisors.
Fixed income pulled in $31.5 billion in net inflows in April alone, according to industry data. Analysts say the bond market is no longer an afterthought. With the Fed expected to move cautiously on rate cuts, these positions are likely to grow. For small RIAs like Claro Advisors, owning the same tools as a $2 billion bank portfolio is now just a few ETF trades away.
