AMD shares jumped 12% on Friday despite a lack of specific company announcements, driven instead by a broader sector rally sparked by Intel's recent earnings. Intel reported stronger-than-expected guidance for the second quarter, which lifted the entire semiconductor industry. The stock surged 23% overnight, pushing its market value above $400 billion for the first time since the 2000 dot-com bubble. AMD, Intel's longtime rival, rose 15% in sympathy, reflecting growing investor confidence in the competitive CPU and data center markets. Analysts have reacted positively to Intel's improved outlook. Citi analyst Atif Malik upgraded Intel from neutral to buy, citing expectations for double-digit server CPU unit growth in 2026, a significant shift from previous projections of only slight growth. Similarly, Suji Desilva of Roth Capital raised Intel's price target, aligning it with AI infrastructure peers like AMD, Marvell, and CoreWeave. While Barclays analyst Tom O'Malley acknowledged the upside, he warned that Intel could still lose market share to AMD, noting a downside case based on potential share erosion. The semiconductor sector is currently experiencing a powerful momentum shift, having risen for 17 of the past 18 trading sessions. The VanEck Semiconductor ETF (SMH) has gained more than 30% this month, with traders increasingly purchasing expensive call options to chase the rally. Implied volatility is rising, indicating that trading options on these stocks is becoming costlier. Memory stocks like Micron and SanDisk have seen particularly bullish options activity, with call volumes outnumbering puts by a 2-to-1 ratio. In contrast, Nvidia has shown relatively lower implied volatility compared to the broader sector ETF. The AI leader, which sits just below its October all-time highs, presents a different risk profile. Despite slower price movement, large traders are still betting on a potential upside ahead of its May 20 earnings report. One notable transaction involved the purchase of 7,500 calls at a $230 strike price expiring on May 15, a $413,000 wager on a 13% increase from current levels. Call volume for Nvidia remains three times higher than put volume. The recent market activity suggests that investors view the chip industry as a cohesive group on an upward trajectory. The strong performance of Intel has acted as a catalyst, validating the growth narrative for competitors and suppliers alike. As data center demand continues to fuel AI infrastructure expansion, the sector remains a focal point for institutional and retail traders, even as option premiums rise and market valuations reach historic levels.
