Conversely, Goldman Sachs increased its share count by 25.59% to 20,162K shares but significantly decreased its portfolio allocation by 80.21%, a pattern also observed with Brown Advisory which increased shares by 2.20% while decreasing allocation by 72.82%.

Invesco QQQ stands out with increases in both share count (+4.26%) and portfolio allocation (+47.73%). This divergence between changes in share counts and portfolio allocations among large holders indicates sophisticated positioning adjustments, possibly reflecting rebalancing activities, differing views on valuation, or portfolio-wide risk management in response to MRVL1's performance relative to other assets.
