Cisco's $1.4B Surge Vaults It to 73rd in Market Activity

Cisco Systems (CSCO) surged 1.03% on September 30, 2025, with a trading volume of $1.40 billion—up 44.21% from the prior day—ranking it 73rd in market activity. The rally followed a strategic update highlighting its cloud infrastructure expansion and enterprise networking dominance. Recent earnings reports underscored robust demand for hybrid work solutions, bolstering investor confidence in its long-term growth trajectory.

Analysts noted heightened institutional buying pressure amid positive sentiment around Cisco’s AI-driven network optimization projects. A key catalyst was its partnership with major cloud providers to enhance data center interoperability, positioning the company to capture a larger share of the $500 billion global networking market. Short-term volatility, however, remained tied to macroeconomic uncertainty and sector-wide earnings revisions.

To run this back-test rigorously I need to pin down a few practical details: 1. Universe – Which market(s) should be scanned each day – e.g. all NYSE + NASDAQ common stocks, or another list? 2. Weighting & position size – Equal-weight (i.e., 1/500 in each name every day) is the usual choice. Is that what you’d like? 3. Entry & exit prices – Typical workflow: rank stocks on the day’s official close, enter at next day’s open (or close), exit at next day’s close (1-day holding period). Please confirm: enter at today’s close and exit tomorrow’s close, or use another convention? 4. Transaction costs & slippage – Ignore them, or apply a per-trade cost (e.g. 1 bp in/out)? 5. Survivorship bias – Use today’s live ticker list, or historical constituents (requires delisted symbols data)? Once these points are clarified I can build the daily trade file and run the back-test from 2022-01-01 to the present.
