(AMAT) saw a trading volume of $2.75 billion, an increase of 87.53% compared to the previous day, ranking it 39th in the stock market. The stock closed down 4.70%.Recent developments highlight mixed signals for the semiconductor equipment manufacturer. A report indicated renewed supply chain bottlenecks in key raw material shipments, raising concerns over production timelines for its next-gen lithography systems. Meanwhile, internal restructuring efforts to streamline R&D operations have sparked investor uncertainty, though no official details were disclosed. The company’s recent client engagements with Asian foundries remain under scrutiny, with analysts noting potential delays in contract renewals due to shifting demand patterns.
Market participants are closely monitoring AMAT’s response to industry-wide margin pressures. Competitor activity in the EUV segment has intensified, with rival firms announcing capacity expansions that could alter pricing dynamics. Short-term technical indicators suggest heightened volatility, driven by heavy institutional trading activity observed in after-hours sessions. However, long-term fundamentals remain intact, supported by ongoing investments in AI-driven manufacturing solutions.
To run this back-test rigorously I first need to pin down a few practical details: 1. Market universe • Are you referring to U.S.–listed stocks only (NYSE + NASDAQ), or a different equity universe? 2. Weighting & capital allocation • Equal-weight each of the 500 names each day? • Or value-weight by volume or market-cap? 3. Trading frictions • Should we assume zero transaction costs and perfect liquidity, or would you like to include an estimate (e.g., 2 bp per round-turn)? 4. Benchmark (optional) • Would you like the results compared with a benchmark such as SPY? Once these items are confirmed I’ll generate the daily re-balance signals (top 500 by volume, hold 1 trading day), feed them into the back-test engine and present the performance statistics and charts.

Hunt down the stocks with explosive trading volume.
