For investors worried over how expensive the entire stock market has gotten, some stocks are more concerning than others. CNBC Pro looked for stocks with the largest valuation premium in the S & P 500. The names we found have forward price-to-earnings ratios today that are far above the past five years’ average. Among those expensive stocks, we filtered for names that are also hated by analysts because of their valuations. Less than half the analysts that cover these stocks rate them a buy, and the shares already sell close to or above Wall Street’s consensus price target for the next 12 months. Take a look at the list of Wall Street’s 10 most expensive stocks and what analysts have to say about them. Intel is currently trading at an 86% premium compared with the stock’s average forward price-to-earnings ratio over the past five years, and just under one-fifth of analysts covering the stock rate it a buy. Intel is not only one of the most fundamentally expensive stocks in the broader market, but it is also currently the most overvalued stock in the Dow Jones Industrial Average on a technical basis, with the price of its stock trading at about 2.5 standard deviations above its 50-day moving average, according to Bespoke Investment Group. The semiconductor maker’s stock has popped 46% this year boosted by its return to profitability in its second-quarter earnings that suggested recovery in the personal computer market slowdown. But the expensive valuation could mean it’s time to take a breather. Seagate Technology Holdings also made the list of stocks trading more expensive to their historic levels. The data storage company, which has also been facing a slowdown in PC and smartphone demand, is down more than 11% this month, paring its year-to-date gain to 19%. Only 30% of analysts covering Seagate rate it a buy, and analysts believe the stock run has just about topped out, according to FactSet data. Earlier this month, the company was downgraded to equal weight from overweight at Barclays, which issued a price target on Seagate that indicated 9% downside. Pandemic beneficiary International Paper Company is another stock that isn’t too popular among investors, with about 18% of analysts giving the company a buy rating. The stock is currently trading at a 44% premium compared with its average forward price-to-earnings ratio over the past five years, making it the third-highest name on the list. Shares of the pulp and paper producer have declined about 2% so far this year. The stock has gained more than 6.5% this quarter, however, as the company’s inventories climb back to target levels. Other expensive companies in the broader market include real estate stock Digital Realty Trust , potential artificial intelligence beneficiary International Business Machines and used-vehicle retailer CarMax .
