 U.S. semiconductor stocks rebounded on Monday, October 19, after an eight-session losing streak erased approximately $2 trillion in market value, with Nvidia, Advanced Micro Devices and Micron Technology recovering some of their recent losses.
 The Philadelphia Semiconductor Index climbed approximately 2.4% during Monday's trading after falling 11.4% the previous week, its steepest weekly decline since March 2025.
 <a href="https://coincodex.com/stock/NVDA/" rel="noopener noreferrer nofollow">Nvidia gained 1.9%</a>, <a href="https://coincodex.com/stock/AMD/" rel="noopener noreferrer nofollow">AMD advanced 3.5%</a> and <a href="https://coincodex.com/stock/MU/" rel="noopener noreferrer nofollow">Micron rose 3.6%</a> in premarket trading. The recovery followed growing concerns about AI infrastructure spending, higher borrowing costs and whether enormous investments in computing capacity can produce sufficient returns.AI Chip Stocks Lose $2 Trillion in Eight Sessions 
 The Philadelphia Semiconductor Index suffered eight consecutive daily declines through October 16, wiping out roughly $2 trillion in combined market capitalization among its constituent chip companies.
 The decline extended the <a href="https://coinpaper.com/37354/ai-chip-stocks-lose-164-trillion-in-six-sessions-as-nvidia-amd-and-micron-face-renewed-selling-pressure" rel="noopener noreferrer nofollow">$1.64 trillion selloff</a> Coinpaper reported earlier in the week, when Nvidia, AMD and Micron faced sustained pressure despite strong expectations for AI-related demand.
 Micron was particularly hard hit, losing 14.6% last week. Intel declined more than 14%, while semiconductor stocks more broadly suffered from rising Treasury yields and concerns about future Federal Reserve interest-rate increases.
 The downturn was not driven solely by weakness in current chip sales. Investors also questioned the financial sustainability of the companies purchasing expensive AI processors and building the facilities needed to operate them.
 The pressure intensified following reports of slowing growth at major AI developers and rising concerns about the enormous capital committed to future computing infrastructure.
 Earlier uncertainty over <a href="https://coinpaper.com/37053/nvidia-and-amd-stocks-fall-over-openais-20b-revenue-gap" rel="noopener noreferrer nofollow">OpenAI's reported revenue</a> had already demonstrated how quickly shifting expectations for AI customers could affect semiconductor valuations.Nvidia, AMD and Micron Recover as Bond Yields Fall 
 Monday's recovery followed a decline in U.S. Treasury yields and easing crude oil prices, providing some relief to technology companies sensitive to financing conditions.
 Nvidia rose approximately 1.9%, AMD climbed 3.5% and Micron gained 3.6% in the premarket snapshot. Intel advanced 4.2% after JPMorgan upgraded the company from underweight to neutral.
 Marvell Technology and Broadcom also participated in the rebound, gaining approximately 4.7% and 3.5%, respectively.
 However, improving share prices did not eliminate concerns in credit markets.
 CoreWeave, a major purchaser of Nvidia hardware, had experienced a <a href="https://coinpaper.com/37426/coreweave-stock-plunges-22-in-one-week-as-50-billion-debt-and-16-bond-yields-alarm-investors" rel="noopener noreferrer nofollow">22% weekly stock decline</a> as investors questioned its debt-funded expansion. Yields on its 2031 bonds exceeded 16% last week before easing toward 15.13% on Monday.
 Higher yields on existing bonds do not immediately change fixed interest payments, but they can signal more expensive refinancing conditions.AI Earnings Will Test Whether the Recovery Lasts 
 Attention now turns to upcoming quarterly results from major technology companies, which could clarify whether demand for advanced processors remains strong enough to support elevated valuations.
 Lam Research, Texas Instruments and Western Digital are scheduled to report this week, providing further evidence about semiconductor demand, capital expenditure and corporate spending plans.
 Meta's October 21 earnings will also be closely watched because its <a href="https://coinpaper.com/37495/meta-faces-145b-ai-spending-test-as-wall-street-prices-6-stock-swing-ahead-of-october-21-earnings" rel="noopener noreferrer nofollow">AI investment plans</a> could reach $145 billion during 2026.
 Meanwhile, recent <a href="https://coinpaper.com/37428/ai-stock-selloff-tech-funds-lose-475-billion-even-as-global-equity-funds-gain-20-billion" rel="noopener noreferrer nofollow">$4.75 billion withdrawals</a> from technology-focused investment funds illustrate how investors have become more selective despite expectations for strong sector earnings.
 The semiconductor index remained up approximately 57% year to date before Monday's rebound, underscoring the scale of the earlier rally.
 For now, the recovery suggests investors are returning to AI chipmakers after a steep correction. Whether the gains persist will depend on earnings performance, infrastructure financing costs and confidence that AI spending can translate into sustainable profits.
