Berkshire Shares Rise 0.57% as Volume Plummets 33.42% and Falls to 54th in U.S. Market Rankings

Berkshire Hathaway Inc. (BRK.B) closed 0.57% higher on Oct. 13, with a trading volume of $1.56 billion, down 33.42% from the previous day. The stock ranked 54th in terms of volume activity across major U.S. equity markets.

Recent market analysis highlights limited catalysts for near-term volatility in the conglomerate’s shares. While the company’s diversified portfolio and long-term investment strategy remain structural advantages, short-term price action has shown muted responsiveness to broader market trends. Technical indicators suggest a consolidation pattern, with volume contraction signaling reduced speculative interest.

A back-test of a basic RSI-based trading strategy from Jan. 1, 2022, to Oct. 13, 2025, revealed mixed outcomes for Berkshire. The strategy, which entered trades when RSI-14 fell below 30 and exited after one day, generated a total return of -2.37% with an annualized return of -0.49%. Maximum drawdown reached 8.47%, and the Sharpe ratio stood at -0.09. Average trade performance was negative (-0.13%), with winning trades averaging 1.83% and losing trades averaging -2.75%. The results indicate the strategy failed to produce risk-adjusted returns, suggesting mean-reversion signals may require additional filters or longer holding periods for effectiveness.
