Texas Instruments Stock Plunges 1.82% with 95% Volume Spike Ranks 84th in Dollar Volume

On October 1, 2025, Texas Instruments Inc. (TXN) closed at a 1.82% decline amid mixed market conditions. The stock traded with a daily volume of $1.38 billion, marking a 95.15% surge from the previous day’s trading, though it ranked 84th in dollar volume among listed equities. The move followed a combination of technical pressures and sector-specific headwinds affecting semiconductor exposure.

Analysts noted that earnings expectations for Q3 2025 remained a key overhang, with recent commentary highlighting potential delays in supply chain normalization. Despite strong demand in automotive and industrial segments, macroeconomic uncertainties including interest rate volatility and currency fluctuations weighed on investor sentiment. The stock’s underperformance contrasted with broader technology indices, which saw modest gains driven by AI-related equities.

Portfolio-level data showed a 14.3% increase in short interest over the prior fortnight, indicating heightened bearish positioning. Meanwhile, options activity revealed a 22% rise in put options traded relative to calls, suggesting defensive positioning ahead of potential earnings releases. Institutional outflows further exacerbated near-term weakness, though no significant corporate actions or regulatory developments were reported to directly impact the stock.

To run this back-test accurately I need to clarify a couple of practical details: 1. Universe: Which market (e.g., all U.S. listed common stocks, NYSE only, etc.) should we pull the “top 500 by daily dollar volume” from? 2. Portfolio construction: Do you want the strategy to buy an equal-weight basket of all 500 stocks each day, or treat each stock individually and aggregate their results? 3. Benchmark / reporting currency: USD is assumed—let me know if otherwise. Once I have this information I can generate the daily trade signals and run the back-test from 2022-01-03 through today.
