AI Stocks Rebound Amid Market Volatility (SMCI)

• AI chip stocks rebounded Oct 19, 2026; SMCI rose over 4% as Nasdaq and semiconductor index gained • SMCI's P/S ratio (0.56) is far below historical median, but GF Score of 85 signals strong growth potential • Insiders sold $24.44 million in SMCI shares over three months despite gurus adding to positions AI tech stocks rebounded on October 19, 2026, with the Nasdaq up over 1% and the Philadelphia Semiconductor Index up more than 3%, as panic from an eight-day selloff — the longest since 2008 — eased. The decline was tied to funding disruptions rather than weak AI demand; UBS recently raised its 2026 global AI capex forecast to $900 billion. Super Micro Computer (SMCI) jumped over 4%. The San Jose-based server and storage maker, valued at roughly $21.49 billion, trades at a Price-to-Sales ratio of about 0.56, well below its historical median, reflecting its cash-flow-negative status (its P/E of 9.95x is not meaningful in this context). GF Value pegs the stock as 63.9% undervalued, though that should be read as directional given ongoing losses. SMCI holds a GF Score of 85/100, with strong Growth (10/10), Profitability (8/10), and Momentum (8/10) ranks, but a weak Valuation rank (2/10). Eight gurus hold positions, with seven adding recently, though insiders sold $24.44 million in shares over the past three months — a caution flag alongside the bullish growth and profitability metrics.
