Corning's 1.33% Rise Driven by $740M Volume Surge, 168th in U.S. Equity Trading Activity

Corning (GLW) rose 1.33% on October 1, 2025, with a trading volume of $740 million, representing a 43.72% increase from the previous day’s volume. The stock ranked 168th in trading activity among U.S. equities. The move followed a mix of sector-specific dynamics and broader market sentiment shifts.

Analysts noted that Corning’s performance was influenced by a combination of supply chain updates and strategic positioning in optical communications. Recent reports highlighted the company’s focus on expanding its fiber network infrastructure, aligning with long-term industry trends. However, no direct earnings or product announcements were cited as immediate catalysts for the price action.

To run this back-test accurately I need to firm up a few practical details about the strategy and the universe: 1. Market universe • All U.S. exchange-listed common stocks (≈ 7 000 names), or a different region/segment? 2. Execution price and timing • Buy at today’s close and sell at tomorrow’s close, or buy next-day open / sell same-day close? 3. Position sizing • Equal-weight across the 500 names, or weight by (for example) dollar volume? 4. Trading frictions • Should we include an estimate of commissions/slippage, or assume frictionless execution? 5. Benchmark (optional) • Any particular index you’d like to compare the strategy against? Let me know your preferences—once these are set I’ll build the back-test and return the performance statistics.
