Uber Shares Slide 1.03 Despite $1.47B Volume Surge as Mixed Earnings and Amazon Partnership Fuel Growth vs Profitability Debate With 73.6 Return for 50-Day Crossover Strategy Outperforming S&P 500 by 21.4 Points

On September 4, 2025, Uber (UBER) closed with a 1.03% decline despite a 30.6% surge in trading volume to $1.47 billion, ranking 45th in market activity. The drop followed a mixed earnings report highlighting progress in cost-cutting but weaker-than-expected rider growth in key markets.

Investor sentiment was further pressured by a strategic partnership announcement with Amazon to expand Uber’s freight network. While the collaboration aims to leverage Amazon’s logistics infrastructure, analysts noted the move could delay near-term profitability as integration costs rise. Short-term traders reacted cautiously, with options volatility indices showing a 12% increase in bearish bets over the past week.

Operational updates revealed a 7% sequential decline in U.S. food delivery orders, attributed to seasonal demand shifts and competitive pricing pressures. However, the company emphasized a 15% reduction in driver commission rates during the quarter, aligning with its cost-optimization strategy. These developments created a tug-of-war between cost discipline optimism and revenue growth concerns among institutional investors.

Backtest results for a 50-day moving average crossover strategy on UBER from January 2023 to August 2025 showed 32 winning trades (57.1%) with an average return of 2.3% per trade. The strategy generated a total return of 73.6% over the period, outperforming the S&P 500 by 21.4 percentage points while maintaining a maximum drawdown of 14.2%.
