Nvidia is due to release its quarterly earnings after the U.S. stock market closes this Wednesday, making the report a key test of whether the AI investment boom remains intact. Analysts say investors should look beyond revenue and profit to CEO Jensen Huang's comments on whether large-scale spending on AI infrastructure can continue expanding rapidly. Nvidia has exceeded analysts' earnings expectations for 14 consecutive quarters. In its most recent quarter, net profit rose 210% year over year, compared with Wall Street's earlier forecast of 126%. Analysts now expect second-quarter revenue of $92 billion, up from an initial forecast of $78 billion at the start of the year, while profit would need to exceed $51.5 billion to beat current market expectations. Nvidia shares have fallen on the next trading day after each of the past four quarterly reports. Options markets imply a possible 5.3% move after this report, above the average post-earnings move over the past 12 months. Some investors are positioned for a pullback, while HSBC Global Research technology hardware and semiconductor research head Frank Lee raised his price target to $360 from $325, citing Nvidia's strategic partnerships with suppliers and its important role in open-source artificial intelligence.
