MICRON TECHNOLOGY INC
2 expanding manager groups; 3 meaningfully reducing. A divided pattern.
Coatue: 0.2% → 7.5% of reported long-share value; shares +1793.7%.
Brad Gerstner · Altimeter: not reported → 2.5% of reported long-share value; newly reported positive position.
Why it stays in divided signals
At least two distinct active-manager groups each newly reported the position or increased reported shares by at least 10%, raised its allocation by at least 0.5 percentage points, and ended with at least 1% of reported long-share value in the position. 2 groups pass for this company. However, meaningful reducing groups equal or outnumber expanding groups. This does not qualify as clear accumulation.

Four feeds are evaluated, not assumed to agree. Incomplete insider filing windows cannot establish a complete 90-day absence. Only comparable, non-amended full 13F reports contribute to manager-expansion thresholds; giant index/bank portfolios do not qualify a stock merely by holding it.
