Applied Materials (AMAT) and KLA Corporation (KLAC) both supply critical equipment to the semiconductor industry, with AMAT focusing on deposition and etch processes while KLAC specializes in process control and yield management. In recent market activity, both stocks have delivered strong year-to-date gains amid AI-driven demand for advanced chips, though the sector has experienced periodic volatility.

Both AMAT and LRCX operate in the semiconductor equipment sector and have delivered substantial year-to-date gains amid strong demand for AI-related chip manufacturing tools. Recent market activity has seen heightened volatility across the sector, with AMAT experiencing notable intraday and weekly declines while LRCX has retreated from earlier all-time highs.

Price target in focus: $800 per share represents a roughly 51% upside from the July 17 closing price of $529.66 and sits above the stock's all-time high of approximately $740. Strongest bullish factors: Unprecedented wafer fabrication equipment (WFE) spending driven by AI chip demand, multi-year order visibility stretching toward 2030, and record revenue and margin performance.

Applied Materials (AMAT) shares declined approximately 14% over the last 30 days, falling from $617.11 on June 18 to $529.66 by July 17, 2026.

The $300 price target represents approximately 37% upside from KLAC's recent price of roughly $219 and sits above the consensus analyst target of $234 but within the range of the most optimistic Wall Street forecasts. AI-driven semiconductor demand is the strongest bullish catalyst, with wafer fab equipment (WFE) spending projected to reach $145–150 billion in 2026 and potentially $250 billion by 2028.

KLAC shares closed at $219.37, down -2.29% (-$5.13) during the regular trading session, extending a volatile stretch for the semiconductor equipment maker.
