Backtest
The backtest results reveal that SLB's earnings beats yield a modest short-term gain but limited sustained upside, while earnings misses cause initial declines with some recovery after 30 days. Industry-wide, earnings beats and misses in Energy Equipment & Services show minimal impact on stock prices, indicating muted market reactions. This suggests that SLB's stock performance is somewhat sensitive to earnings surprises, unlike the broader industry. Investors should consider short-term trading strategies for SLB around earnings events and be cautious about relying on earnings surprises alone for long-term investment decisions in this sector.
