LSCC vs SEDG: SPOTLIGHT Buys vs MONITOR Signals
How did Lattice Semiconductor (LSCC) and SolarEdge Technologies (SEDG) fare under JumpstartSignal's 5-stage screening pipeline across our full 2012–2025 walk-forward backtest? We flagged LSCC 2 times (8 signal days, first signal in 2014) and SEDG 10 times (26 signal days, first signal in 2017). Every entry price, return, and SPY comparison below is from the frozen backtest snapshot.
📌 Note: SEDG only ever reached our MONITOR watchlist tier, it was never promoted to a SPOTLIGHT or OPPORTUNITY buy signal. LSCC 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, SEDG triggered entries 10× versus 2× for LSCC. 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 SEDG?
No. SEDG 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. LSCC, by contrast, did reach SPOTLIGHT or OPPORTUNITY in our pipeline; that asymmetry is the core story of this page.
Is LSCC or SEDG a better momentum stock?
These two are not directly comparable as momentum buys. LSCC reached our buy tiers and averaged +245% alpha per buy signal across 2 clusters. SEDG only ever cleared the MONITOR watchlist (10 clusters, never promoted to a buy), so it has no buy-tier alpha. MONITOR signals are watch-only and not comparable to executed buy signals.
When did JumpstartSignal first flag LSCC?
Jun 6, 2014 at an entry price of $8.15 (SPOTLIGHT or OPPORTUNITY buy signal). That signal has returned +888% held to the snapshot date, versus +329% for SPY over the same period.
When did JumpstartSignal first flag SEDG?
Aug 21, 2017 at an entry price of $26.05 (MONITOR watchlist tier only). That signal has returned +19% held to the snapshot date, versus +223% 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 end-of-day OHLCV and frozen at snapshot time. See our methodology for details.
