As of January 20, 2026, a number of stocks within the health care sector are registering significant momentum indicators, which may be signaling caution for investors relying on short-term strength for trading decisions. The Relative Strength Index (RSI), a momentum oscillator that measures the speed and change of price movements, helps identify overbought or oversold conditions in a stock's trading range. Typically, an RSI value above 70 is interpreted as overbought, implying that the asset could be poised for a price pullback.
Among the health care stocks experiencing elevated RSI levels, three have emerged prominently: Erasca Inc (NASDAQ:ERAS), ImmunityBio Inc (NASDAQ:IBRX), and Venus Concept Inc (NASDAQ:VERO). These companies reflect pronounced recent price movements and momentum scores, suggesting increased investor enthusiasm that may soon be tempered.
Venus Concept Inc (NASDAQ: VERO)
Venus Concept, a company specializing in medical aesthetic technology, has witnessed a remarkable price surge in recent trading sessions. According to regulatory filings, Madryn Asset Management disclosed holding a 91% stake in Venus Concept as of early January 2026, signaling substantial investor confidence. The investment was reported as a financial stake rather than an acquisition interest.
Venus Concept's stock price has escalated approximately 426% over the last five days leading to January 20, reaching a 52-week high of $14.50 per share. Closing Friday at $7.89, shares gained 451.8% over the same period. Correspondingly, the stock exhibits an RSI of 95.9, substantially above the overbought threshold. Additionally, the Edge Stock Ratings momentum score for Venus Concept stands at an exceptionally high 99.01, reflecting powerful upward movement and trading momentum.
ImmunityBio Inc (NASDAQ: IBRX)
ImmunityBio has also experienced noteworthy gains, with shares advancing over 100% year to date, spurred by promising preliminary fourth-quarter financial results and clinical trial data. On Friday leading to January 20, ImmunityBio announced that enrollment numbers in its randomized registrational clinical trial, QUILT-2.005, exceeded internal expectations. This study targets BCG-naïve non-muscle-invasive bladder cancer (NMIBC) patients.
Over the past five days, ImmunityBio's stock rose by roughly 136%, closing at $5.52 on Friday, near its 52-week high of $5.58. The stock's RSI reached 95.4, once again indicating extreme overbought conditions that often precede periods of price stabilization or decline.
Erasca Inc (NASDAQ: ERAS)
Erasca Inc displays a strong momentum score — with the Benzinga Edge Rankings registering a near-peak momentum rating of 99.73. Despite a slight decline of 1.25% to $9.50 on the trading day before the report, the company is still one of the notable health care stocks drawing considerable investor attention.
While detailed RSI values were not explicitly provided for Erasca, the elevated momentum and price trends underscore a similar pattern to those seen in ImmunityBio and Venus Concept. The momentum signals suggest Erasca is among the peers with robust recent performance and potential overextension in price levels.
Understanding RSI and Momentum Indicators in Stock Analysis
The RSI is a widely used technical analysis tool that compares the magnitude of recent gains to recent losses to determine overbought or oversold conditions in stock price movements. A reading above 70 often prompts traders to consider that a stock may have risen too far, too fast, and could be due for a correction. Conversely, values below 30 could indicate undervaluation or selling exhaustion.
Alongside RSI, momentum scores — as provided by platforms such as Edge Stock Ratings — synthesize multiple factors including price trends, volume, and volatility to gauge the strength of a stock's price movement over different timeframes. Stocks with momentum scores nearing 100 are regarded as having extremely strong upward price action, though they can also be vulnerable to pullbacks if the overbought conditions induce profit-taking.
