Several S&P 500 stocks are flashing overbought signals with RSI readings above 70, suggesting a potential near-term retracement despite recent market gains.

The S&P 500 climbed 1.4% during the holiday-shortened week, yet technical indicators suggest several high-performing stocks may be overextended and due for a price correction [1]. Investors are monitoring the 14-day relative strength index (RSI)—a momentum oscillator where readings above 70 typically signal that a stock has advanced too quickly and may face a near-term pullback [2, 4].

## Technical signals and market momentum
Marathon Petroleum currently leads the list of technically overbought S&P 500 names with an RSI of 90, following a 7% gain this week [2]. Intel shares also show signs of being stretched, with an RSI of 80—a level the stock last reached in February, which preceded a 23% decline over the following weeks [2]. Intel’s recent 21% weekly surge was driven by reports of potential investments involving Apple and Taiwan Semiconductor Manufacturing Company, pushing its year-to-date gains to nearly 80% [2].

Other major names are flashing similar signals. Merck & Co. shares rose 5% this week to reach an RSI of 73, supported by a recent upgrade to an outperform rating from BMO Capital Markets [1]. S&P Global also appeared on the overbought list with an RSI of 72 and a 3% weekly gain, following its inclusion as a top pick in a Morgan Stanley 2026 outlook [1]. IBM, which saw a 7% weekly increase, is trading with an RSI near 79, fueled by investor interest in the company’s quantum computing progress [2].

## Oversold territory and outlook
While some stocks show signs of exhaustion, others have moved into oversold territory, defined by an RSI reading below 30 [1]. Lennar fell 3% this week, bringing its RSI to 28, after several firms downgraded the homebuilder following fourth-quarter results and first-quarter guidance that missed expectations [1]. Analysts at Bank of America cited concerns over margin and revenue outlooks, noting that the stock continues to trade at a premium despite headwinds in return-on-equity [1].

## What to watch
*   **RSI Reversion:** Monitor whether stocks with RSI readings above 70, such as Marathon Petroleum and Intel, experience the historical retracement patterns often associated with these levels [2].
*   **Earnings and Guidance:** Watch for further updates on 2026 earnings estimates, particularly for companies like Lennar that have recently faced downward revisions to their margin and revenue outlooks [1].
*   **Institutional Sentiment:** Observe if analysts maintain their current ratings on overbought names like IBM, where Morgan Stanley recently assigned an equal-weight rating despite acknowledging the company's leadership in quantum technology [2].

The divergence between the S&P 500’s broad upward momentum and the technical exhaustion seen in individual high-flyers leaves the market in a precarious position as the new year approaches. Whether these overbought names undergo a controlled consolidation or a sharper correction remains the primary question for momentum-focused traders.
