Financial Services is heavily represented through Interactive Brokers, S&P Global, Visa, and Intercontinental Exchange. This indicates a strategic focus on specific high-growth and established sectors within these industries.
Recent Changes
Several holdings show significant reductions in shares during the prior period. Broadcom, Alphabet, Taiwan Semiconductor, Interactive Brokers, S&P Global, Analog Devices, CBRE, Applied Materials, Visa, and Intercontinental Exchange all experienced share decreases ranging from 11.85% to 48.82%.

The selection criteria seem to favor established large-cap entities with strong market positions, though the significant reduction in Applied Materials' position stands out as an exception, showing a much larger percentage decline compared to other holdings. This approach suggests a focus on quality and market leadership, albeit with a notable concentration in a select group of stocks.
