Qualcomm Shares Surge on AI Optimism Rank 47th in U.S. Turnover as Volume Jumps 68%

Qualcomm Inc. (QCOM) surged 2.37% to close on Sept. 24, with a trading volume of $1.56 billion — a 68.02% increase from the prior day — ranking it 47th among U.S. equities by turnover. The chipmaker’s performance followed a broader market rebound amid renewed optimism over AI-driven demand for semiconductor solutions.

Analysts highlighted growing investor confidence in Qualcomm’s strategic positioning in next-generation mobile and AI infrastructure. Recent industry reports underscored the company’s leadership in 5G modem technology and its expanding partnerships with automotive and IoT sectors. However, supply chain dynamics and global regulatory scrutiny remain key risks for the stock, according to market observers.

To run this back-test I need to pin down a few practical details that aren’t fully specified yet: 1. Universe • Should I rank all U.S. listed common stocks (the usual default) or a different equity universe? 2. Ranking & execution convention • Rank by today’s turnover (shares-traded volume) at the close, then buy at the same close and liquidate at tomorrow’s close? • Or rank on yesterday’s volume, buy at today’s open, and sell at today’s close? 3. Position sizing • Equal-weight across the 500 names each day (0.2 % of the portfolio per stock) and fully rebalance daily? 4. Frictions • Is it OK to ignore transaction costs and slippage for this first pass? If the defaults below are acceptable, please just let me know and I’ll proceed immediately: • Universe: All U.S. common stocks whose primary listing is on NYSE, NASDAQ or AMEX. • Ranking: sort by today’s closing share volume; buy at the close; hold one trading day; sell at next day’s close. • Weights: equal-weight across the 500 selected names each day. • Frictions: none. Feel free to tweak any of the above—once confirmed I’ll generate the data-retrieval plan and run the back-test.
