S&P 500 Slides for Fourth Week as Geopolitical Tensions Trigger RSI Extremes
The S&P 500 extended its losing streak to four consecutive weeks, pressured by ongoing geopolitical conflict in the Middle East. This broad market decline has pushed several individual stocks into technically extreme territory, as measured by the 14-day Relative Strength Index (RSI). An RSI below 30 typically signals an “oversold” condition, suggesting a stock may have declined too rapidly and could be due for a rebound. Conversely, an RSI above 70 indicates an “overbought” condition, warning that a stock may be extended to the upside and vulnerable to a pullback. Analysis from CNBC Pro, using LSEG data, screened for S&P 500 stocks meeting these RSI thresholds while also posting significant weekly price moves—at least a 5% decline for oversold candidates and a 5% gain for overbought ones.
Consumer Staples Lead the Oversold List
As conflict escalated, consumer sentiment showed signs of strain, with several defensive consumer staples names appearing on the oversold roster. McCormick (MKC) emerged as the third-most oversold stock in the index, with an RSI of 21.3. The stock fell more than 7% for the week and has now dropped over 20% in the past month. However, it saw a relative bounce on Friday following news that Unilever is in talks to separate its food business and merge it with McCormick. Analysts acknowledged the strategic logic but highlighted risks. “We acknowledge the significant strategic merit and likely compelling EPS accretion from this potential transaction but also concede the hefty likely deal value, execution risk and resultant majority ownership of the combined entity by Unilever shareholders could dampen initial investor enthusiasm,” wrote Andrew Lazar, an analyst with an Equal Weight rating on McCormick.
Other consumer staples on the oversold list include General Mills (GIS) and Conagra Brands (CAG). The most extreme oversold reading, however, belonged to Genuine Parts (GPC), an automotive and industrial products firm, which recorded an RSI of just 13.6, indicating severe downward pressure over the recent period.
Energy Stocks surge into Overbought Territory
While some sectors weakened, energy companies rallied sharply on the back of rising oil prices driven by the conflict. This momentum propelled several energy stocks into overbought territory. APA (APA) topped the list with an RSI of 81.7, after gaining roughly 14% for the week. Occidental Petroleum (OXY), Ciena (CIEN), and Devon Energy (DVN) were also flagged as overbought following strong weekly gains.
The sustained conflict suggests oil prices—and by extension, these energy equities—could see further support. Nevertheless, the elevated RSI readings serve as a cautionary signal for investors, implying that recent gains may have been overextended and that a period of consolidation or profit-taking could be imminent. This technical divergence, where the broader market declines while a specific sector rallies on commodity-driven news, underscores the nuanced and sector-specific dynamics currently at play.
Understanding the Signals: Context is Key
It is crucial to interpret RSI extremes within the broader context. An oversold RSI does not guarantee an immediate reversal; a stock can remain technically oversold during a sustained downtrend if fundamental drivers are weak. Similarly, an overbought RSI in a strong uptrend—such as energy stocks benefiting from a geopolitical risk premium—may persist longer than a simple indicator might suggest. Investors should always combine technical analysis with fundamental research, considering factors like earnings outlook, valuation, and the specific catalysts behind recent price action before making trading decisions based solely on RSI readings.
