MANH vs CMCSA: Buy Signal vs Watchlist-Only
How did Comcast (CMCSA) and Manhattan Associates (MANH) fare under JumpstartSignal's 5-stage screening pipeline across our full 2012–2025 walk-forward backtest? We flagged CMCSA 26 times (544 signal days, first signal in 2012) and MANH 3 times (7 signal days, first signal in 2012). Every entry price, return, and SPY comparison below is from the frozen backtest snapshot.
📌 Note: CMCSA only ever reached our MONITOR watchlist tier, it was never promoted to a SPOTLIGHT or OPPORTUNITY buy signal. MANH did reach SPOTLIGHT or OPPORTUNITY. That asymmetry is the story of this comparison.

What This Teaches
Signal frequency is not opinion; it's the pipeline firing or not firing against the same rules. Over the 2012–2025 window, CMCSA triggered entries 26× versus 3× for MANH. The lesson here isn't that one company is better than the other; it's that the template is tuned for a specific kind of setup and this pair shows which stock's price behaviour kept offering that setup.

FAQ
Did JumpstartSignal ever buy CMCSA?
No. CMCSA only ever cleared our weekly MONITOR tier, a watchlist of stocks matching some but not all of our buy criteria. MONITOR signals are published for research context, not executed as trades; only SPOTLIGHT and OPPORTUNITY signals enter the backtested portfolio. MANH, by contrast, did reach SPOTLIGHT or OPPORTUNITY in our pipeline; that asymmetry is the core story of this page.
Is CMCSA or MANH a better momentum stock?
In our 14-year backtest, CMCSA had an average alpha of -232% per signal versus +345% for MANH. CMCSA produced 26 MONITOR watchlist clusters vs 3 SPOTLIGHT or OPPORTUNITY buy-signal clusters for MANH. Note the tier difference: MONITOR clusters are watchlist-only and were never promoted to buy signals, so cluster counts are not directly comparable across tiers.
When did JumpstartSignal first flag CMCSA?
Apr 26, 2012 at an entry price of $10.52 (MONITOR watchlist tier only). That signal has returned +183% held to the snapshot date, versus +524% for SPY over the same period.
When did JumpstartSignal first flag MANH?
Apr 25, 2012 at an entry price of $12.48 (SPOTLIGHT or OPPORTUNITY buy signal). That signal has returned +1110% held to the snapshot date, versus +528% for SPY.
Does this mean one stock is a buy and the other isn't?
No. Historical signal frequency and past returns are not buy recommendations. Our pipeline identifies entries that would have matched the template historically. Past performance does not guarantee future results. Use these pages as methodology research, not investment advice.
Where does the underlying data come from?
All entries on this page come from the R30 walk-forward validated backtest covering 2012–2025 (the 'seo_active' snapshot in our golden archive). Entry prices, returns, and SPY comparisons are computed from Stooq end-of-day OHLCV and frozen at snapshot time. See our methodology for details.
