EverHint Signal — SMA20 × SMA50 Crossover — December 09, 2025

What This Signal Is (Quick)

The SMA20 × SMA50 Crossover is one of the most reliable trend-following strategies in technical analysis. It tracks when the 20-day simple moving average crosses the 50-day simple moving average—a signal that short-term momentum is shifting relative to the medium-term trend.

Buy Signals ("Golden Cross") occur when SMA(20) crosses above SMA(50), indicating that recent price action is accelerating upward and potentially starting a new bullish trend. These setups work best for medium-term positions (4-12 weeks) and tend to have fewer false signals than faster EMA-based strategies.

Sell Signals ("Death Cross") occur when SMA(20) crosses below SMA(50), signaling that short-term momentum is weakening. These can mark exit points for existing positions or warn of potential trend reversals.

How We Ranked Today (Reader Version)

Today's signals are ranked by RSI(14), with lower RSI values ranked higher for buy signals (indicating more oversold conditions with potential upside) and higher RSI values for sell signals. This approach helps identify crossovers that may offer better risk/reward entry points.

We've overlaid three additional data layers:

• Insider Net (USD): Net insider buying or selling over the last 90 days (Purchases minus Sales only—ignoring awards, exercises, and tax transactions)
• Days → Earnings: Time until next earnings report (helps assess event risk)
• Analyst Coverage: Mentioned in context where available

These signals are for educational use, back-testing, and research. Always do your own due diligence.

Field Notes

Understanding the Metrics:

• RSI(14): Relative Strength Index on a 0-100 scale. Below 30 = oversold, above 70 = overbought. For buy signals, lower RSI can indicate better entry points. For sell signals, higher RSI suggests distribution.

• SMA Crossovers: These are "fresh" crossovers that occurred today. The 20-day average just crossed the 50-day average, confirming a shift in momentum.

• Insider Net: Only includes actual Purchases (P) and Sales (S). We ignore Awards (A), Exercises (M), and Tax payments (F) because they don't reflect open-market conviction.

• Days → Earnings: Time until next quarterly report. Less than 7 days = high volatility risk. More than 30 days = lower event risk.

Sector Observations:

• Buy signals concentrated in Financials (4 signals: COF, WAL, JEF, HBAN) - suggesting potential sector rotation into banks
• Consumer Cyclical strength (4 signals: CVNA, URBN, MTH, SON) - discretionary spending names breaking out
• Basic Materials showing life (3 signals: EXK, HMY, PPTA) - precious metals and critical minerals
• Sell signals dominated by Utilities (5 signals: AEE, ATO, CMS, BEP, SRE) - defensive sector rolling over
• Tech sell signals (AMD, MRVL) - chip stocks facing headwinds despite AI tailwinds

Strategy Context:

SMA crossovers are slower and more deliberate than EMA strategies. They produce fewer signals but tend to catch more sustained trends. The 20×50 cross is particularly effective for swing trades lasting 4-12 weeks.

Vlad's Take (EverHint)

Today's market backdrop: S&P 500 essentially flat (-0.004%), Nasdaq up +0.31%, Dow down -0.34%. Mixed signals with tech showing relative strength while blue chips lagged. The VIX closed at 16.91, indicating normal-to-slightly-elevated volatility—not panic, but enough to warrant disciplined risk management. Small-caps outperformed modestly (Russell 2000 +0.42%), suggesting some appetite for risk. Treasury yields rose (10Y at 4.182%), continuing to pressure rate-sensitive sectors. Crypto had a strong day with Bitcoin +2.57% and Ethereum +6.55%. Overall: Cautiously constructive environment with sector rotation in play.

Given this backdrop, the SMA crossover signals are telling an interesting story. The buy-side concentration in Financials (COF, WAL, JEF, HBAN) aligns with rising yields—banks typically benefit from steeper yield curves. The sell signals in Utilities confirm this rotation away from rate-sensitive defensives.

What concerns me: Insider selling is heavy on several buy signals (CVNA -$51.6M, RDDT -$11.7M, COF -$4.2M). While the technicals are bullish, insiders are heading for the exits. The exception is WAL, where the CFO actually bought $308K—that's a rare positive signal worth noting.

On the sell side, the AMD and MRVL death crosses are significant. These are major AI infrastructure plays, and the technical breakdown coincides with competitive concerns (Marvell potentially losing Amazon/Microsoft business). The sector may be consolidating after a massive run.

Trading approach for SMA crossovers:

• Use tiered entries (25-50% position on the cross, add on pullbacks to the SMA20)
• Set stops below the SMA50 (the line that was just crossed)
• For buy signals with heavy insider selling, reduce position size or wait for confirmation
• For sell signals, consider these as exit alerts for existing longs rather than short entries
• Given the elevated VIX, keep position sizes modest and use wider stops

The golden crosses in Financials look like the cleanest setups. The Consumer Cyclical names (CVNA, URBN) are extended (high RSI) despite the crosses—wait for pullbacks. And watch those Utilities death crosses—if you're holding defensive positions, this is your warning shot.
