Why We Flagged VEEV but Only Watched WDC
How did Veeva Systems (VEEV) and Western Digital (WDC) fare under JumpstartSignal's 5-stage screening pipeline across our full 2012–2025 walk-forward backtest? We flagged VEEV 1 time (2 signal days, first signal in 2017) and WDC 18 times (224 signal days, first signal in 2012). Every entry price, return, and SPY comparison below is from the frozen backtest snapshot.
📌 Note: WDC only ever reached our MONITOR watchlist tier, it was never promoted to a SPOTLIGHT or OPPORTUNITY buy signal. VEEV did reach SPOTLIGHT or OPPORTUNITY. That asymmetry is the story of this comparison.

What This Teaches
Stock screening is about frequency, not preference. WDC was flagged 18× and VEEV was flagged 1× because WDC's weekly closes repeatedly matched the confluence we score for. That's why we publish the full record: the absence of a signal on a great company is as instructive as a signal on a mediocre one.

FAQ
Did JumpstartSignal ever buy WDC?
No. WDC 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. VEEV, by contrast, did reach SPOTLIGHT or OPPORTUNITY in our pipeline; that asymmetry is the core story of this page.
Is VEEV or WDC a better momentum stock?
These two are not directly comparable as momentum buys. VEEV reached our buy tiers and averaged +125% alpha per buy signal across 1 cluster. WDC only ever cleared the MONITOR watchlist (18 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 VEEV?
Feb 6, 2017 at an entry price of $43.31 (SPOTLIGHT or OPPORTUNITY buy signal). That signal has returned +371% held to the snapshot date, versus +246% for SPY over the same period.
When did JumpstartSignal first flag WDC?
May 10, 2012 at an entry price of $24.45 (MONITOR watchlist tier only). That signal has returned +923% held to the snapshot date, versus +545% 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.
