Arm's 2.35% Jump Driven by 101% Surge in $0.78B Volume, Ranking 154th in Daily Equity Activity
On October 6, 2025, Arm HoldingsARM-- (ARM) saw a 2.35% rise in its stock price, with a trading volume of $0.78 billion, marking a 101.46% increase compared to the previous day. This volume ranked the stock 154th among all equities traded that day, reflecting heightened investor interest.
Recent developments highlight Arm’s strategic positioning in the semiconductor sector. The company’s focus on expanding its licensing model for AI-driven chip architectures has drawn attention from institutional investors. Analysts note that Arm’s partnerships with major cloud providers and its roadmap for next-generation RISC-V-based solutions are key drivers of short-term momentum.
Market participants remain cautious about macroeconomic headwinds, including rising interest rates, which could pressure growth-oriented tech stocks. However, Arm’s diversified client base and cost-cutting measures have bolstered its resilience compared to peers. Short-term options activity also suggests a balance between bullish and bearish bets, with no clear directional bias emerging.
To run this back-test robustly, I need to nail down a few practical details about how you’d like the portfolio constructed and how trades are executed. Could you confirm (or adjust) the following? 1. Universe • Should we look at all U.S. common stocks (NYSE + NASDAQ + AMEX), or a different universe? 2. Volume metric • Rank by daily **share** volume or **dollar** volume? 3. Execution price • Buy at today’s close and sell at tomorrow’s close (close-to-close return), or some other convention (e.g., next-day open)? 4. Rebalancing / overlap • Each day we refresh the list, hold all 500 names for exactly one day, then fully exit – i.e., a pure one-day turnover strategy. Is that correct? 5. Transaction costs & slippage • Should we assume zero trading costs, or build in a commission/slippage estimate? 6. Benchmark • Any specific benchmark you’d like to compare against (e.g., S&P 500 total return)? Once those points are clear, I can lay out the data retrieval steps and run the back-test.
