In its latest SEC filing for the third quarter, First Citizens Bank & Trust Co. expanded its position in Vanguard S&P 500 ETF by 4.0%, acquiring an additional 1,886 shares to bring its total to 49,191 shares. The ETF now represents 0.5% of the bank’s overall portfolio and ranks as its 23rd largest holding. At the end of the period, the stake was valued at $30.12 million, reflecting continued confidence in broad U.S. large-cap exposure through a passive indexing vehicle.

TRB Advisors LP disclosed a 72.7% increase in its VOO position during the third quarter, adding 200,000 shares to reach a total of 475,000 shares. This stake now accounts for 57.5% of the firm’s assets under management and represents its single largest investment. As of the filing date, the position was worth $290.88 million, underscoring the advisor’s strategic tilt toward S&P 500–linked passive instruments.

Cullen Frost Bankers Inc. reduced its VOO allocation by 1.6% in the third quarter, selling 834 shares to end the period with 51,459 shares. The remaining position was valued at $31.51 million. This modest decrease suggests a tactical rebalancing rather than a shift away from broad large-cap U.S. equity exposure, as VOO continues to offer low-cost market tracking with diversified sector weights.
