StockStory favors Nova (NVMI), questions Teradyne (TER) and AAON on valuation

StockStory said May 14, 2026, that Nova Ltd. (NVMI) is its preferred high-valuation stock among three names reviewed, while expressing caution on Teradyne (TER) and AAON Inc. (AAON) because of elevated forward earnings multiples. Nova, an Israel-based supplier of quality-control systems for semiconductor manufacturing, traded at $517.44, implying a 48.8 times forward price-to-earnings ratio. Teradyne, a U.S. maker of automated semiconductor test equipment, traded at $359.90, or 52.8 times forward earnings. AAON, which makes HVAC equipment for commercial and other buildings, traded at $140.25, or 55.3 times forward earnings. The report framed high-multiple stocks as vulnerable to pullbacks if investor sentiment weakens, while arguing that some companies can justify premium valuations through stronger growth and competitive positioning.
