Berkshire's $263B book stayed 91% concentrated in its top 10, but the edges moved: a new $2.65B Delta stake and $1B+ more GOOG alongside a tripled GOOGL position, funded by deep cuts to CVX (−35%), STZ (−95%) and NUE (−39%), plus full exits from V, MA, UNH and AON. The pattern reads as rotation out of payments and energy into airlines and Alphabet. Clone rank #37 of 59 — copying Berkshire has lagged SPY by ~4pt a year over three years.
