Why We Flagged RMBS but Only Watched NFLX
How did Netflix (NFLX) and Rambus (RMBS) fare under JumpstartSignal's 5-stage screening pipeline across our full 2012–2025 walk-forward backtest? We flagged NFLX 15 times (188 signal days, first signal in 2014) and RMBS 2 times (3 signal days, first signal in 2014). Every entry price, return, and SPY comparison below is from the frozen backtest snapshot.
📌 Note: NFLX only ever reached our MONITOR watchlist tier, it was never promoted to a SPOTLIGHT or OPPORTUNITY buy signal. RMBS 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, NFLX triggered entries 15× versus 2× for RMBS. 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 NFLX?
No. NFLX 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. RMBS, by contrast, did reach SPOTLIGHT or OPPORTUNITY in our pipeline; that asymmetry is the core story of this page.
Is NFLX or RMBS a better momentum stock?
In our 14-year backtest, NFLX had an average alpha of +63% per signal versus +625% for RMBS. NFLX produced 15 MONITOR watchlist clusters vs 2 SPOTLIGHT or OPPORTUNITY buy-signal clusters for RMBS. 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 NFLX?
Feb 5, 2014 at an entry price of $5.78 (MONITOR watchlist tier only). That signal has returned +1344% held to the snapshot date, versus +381% for SPY over the same period.
When did JumpstartSignal first flag RMBS?
Mar 7, 2014 at an entry price of $9.66 (SPOTLIGHT or OPPORTUNITY buy signal). That signal has returned +1078% held to the snapshot date, versus +347% 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 R27 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.
