Stocks including Northrop Grumman and Advanced Micro Devices appear overbought after this week’s rally, according to one widely used technical metric. The three major U.S. indexes notched strong gains this week, powered by a slew of positive earnings reports and developments on trade deals. The S & P 500 rose 1.5% in the period after recording five record closes this week alone and notching 14 total record closes this year. The 30-stock Dow gained roughly 1.3% this week, and the Nasdaq Composite rose 1%. Stocks that popped during this winning run could be on risky ground moving forward, though. Using the CNBC Pro stock screener tool , we identified the most oversold and overbought stocks this week by their 14-day relative strength index. An RSI above 70 suggests that a stock is overbought and could see a decline, while a result below 30 indicates a stock could be oversold and may be due for a boost. Take a look at the overbought names below, which were each up at least 5% this week. Chipmaker Advanced Micro Devices made the list this week with an RSI of nearly 77. Shares rallied 6% this week. Earlier this month, the company said it will soon resume shipments of its MI308 artificial intelligence chips to China, once license applications are approved by the U.S. Commerce Department. Defense and aerospace company Northrop Grumman jumped 9.8% this week, putting the stock in the overbought group with an RSI of about 73. Northrop on Tuesday posted a second-quarter revenue beat along with a guidance raise for the full year. CEO Kathy Warden said on a conference call with analysts that the company believes revenue from its B-21 stealth bomber could potentially exceed 10% of total revenue “in the future.” Other stocks that have high RSIs and could see their shares dip include Block , Newmont and GE Vernova . GE Vernova shares rallied about 12% this week on strong second-quarter results, which led analysts from firms including Citi and Bank of America to raise their price targets on the stock. International Business Machines , Texas Instruments and Philip Morris International are considered some of the broader market’s most oversold companies, per their high RSIs. IBM shares slid more than 9% this week after the tech company’s second-quarter software revenue came in below expectations, even though its overall revenue and earnings topped analysts’ forecasts, per LSEG. The stock has an RSI of around 26. Tobacco giant Philip Morris fell on the back of lackluster results, which missed second-quarter revenue expectations. Wall Street was also disappointed by the company’s Zyn nicotine shipments. Shares dropped almost 10% this week, and the stock had an RSI reading of about 29.
