Charter Communications Trailing with $0.40 Billion Volume, 296th in Daily Trading Activity as Investor Confidence Fades

On October 8, 2025, Charter Communications (CHTR) reported a trading volume of $0.40 billion, ranking 296th among stocks in terms of daily trading activity. The stock closed 0.76% lower, reflecting a decline in investor sentiment ahead of its scheduled earnings release later this month.

Analysts noted that the dip followed a broader sector-wide pullback in communications services stocks, driven by renewed concerns over macroeconomic uncertainty. Recent regulatory developments in the broadband industry also contributed to cautious positioning, with investors awaiting clarity on potential spectrum auctions and capital expenditure guidance from management.

Technical indicators showed mixed signals for the stock, with short-term momentum indicators pointing downward while longer-term trends remained within key support levels. Market participants are closely monitoring upcoming capital allocation decisions, as Charter’s ability to balance debt reduction with network expansion remains a critical factor for future performance.

To run this back-test I need to pin down a couple of practical details: 1. Universe • Which market do you want to scan each day—e.g. all U.S.-listed common stocks (NYSE + NASDAQ + AMEX), only S&P 500 constituents, or something else? 2. Entry & exit price convention • Should we rank by today’s trading volume, enter at today’s close, and exit at tomorrow’s close (one full trading day), or enter at the next day’s open and exit at that day’s close? • Equal-weight across the 500 names each day? 3. Cash management / slippage • Any transaction cost or commission assumptions, or is it fine to ignore them for this first pass? Once I have these points I can generate the daily buy/sell signals and run the back-test from 2022-01-03 (first trading day of 2022) up to today.
