EverHint Signal — EMA10 × EMA30 Crossover — December 17, 2025

What This Signal Is (Quick)

The EMA10 × EMA30 Crossover strategy detects fresh crossovers between the 10-day exponential moving average (EMA10) and the 30-day exponential moving average (EMA30) that occur on today's close.

Buy Signal (EMA10_x_EMA30_Buy): EMA(10) crosses above EMA(30) on today's close. This suggests short-term momentum is overtaking the medium-term trend, indicating acceleration in upward price movement. Ideal for swing trading with 1-4 week holding periods.

Sell Signal (EMA10_x_EMA30_Sell): EMA(10) crosses below EMA(30) on today's close. This suggests short-term momentum is weakening below the medium-term trend, signaling deceleration or potential reversal of upward movement. Can indicate exit points or short entry opportunities.

Key Characteristics:

• Uses two EMAs (both exponential) for faster response to price changes
• More responsive than EMA10 x SMA50, generating more frequent signals
• Better suited for capturing short-to-medium term momentum shifts
• Higher sensitivity means more signals but also higher whipsaw risk in choppy markets

How We Ranked Today (Reader Version)

For sell signals, lower RSI also ranks higher as it indicates weaker momentum and more confirmation of downside.

• RSI < 30: Oversold — Strong opportunity zone
• RSI 30-50: Neutral to slightly oversold — Good entry/exit zone
• RSI 50-70: Neutral to overbought — Momentum present but less room
• RSI > 70: Overbought — Caution warranted

We also overlay:

• Insider Net (USD): Net insider buying or selling over the last 90 days (Purchases - Sales only)
• Days to Earnings: Proximity to the next earnings report affects volatility risk

Vlad's Take (EverHint)

Market Backdrop: Today the S&P 500 dropped -1.2% to close at 6,721, Nasdaq fell harder at -1.9% to 22,696, and the Dow declined -0.6% to 47,886. Tech-led selloff dominated as investors rotated out of mega-cap names. The VIX spiked to 17.62 (up 7.1%), indicating elevated volatility—not panic territory, but caution is warranted. Small-caps underperformed with the Russell 2000 down -1.1%, suggesting defensive positioning. Bitcoin dropped -2.4% to $85,706, and Ethereum fell -5.1% to $2,811, reflecting broader risk-off sentiment. Treasury yields eased slightly (10Y at 4.149%, down 3 bps), offering modest support for growth names. Overall: Risk-off environment with tech weakness and rising volatility.

Given this backdrop, today's EMA10 × EMA30 crossovers carry mixed signals. The 21 buy signals emerging in this environment are contrarian plays—stocks crossing bullish while the market sells off. These setups require extra scrutiny. Focus on quality names with strong fundamentals and avoid chasing momentum blindly. The VIX at 17.62 suggests tighter stops are prudent.

On the sell side, the 40 signals include some high-profile names like PWR, CLS, and TMDX breaking down. The energy sector appears weak (CNQ, SEI, NE, CRGY all showing sell signals), reflecting broader commodity pressure. Healthcare names like TMDX (RSI 17.8—extremely oversold) and STE might be oversold bounces waiting to happen, but confirm with broader sector trends first.

Trading Tips:

• Tiered Entries: Don't deploy full capital at once. Scale in 30-40-30 across multiple days to average better pricing.
• Tighter Stops: With VIX elevated, consider 5-7% stops rather than the usual 8-10%.
• Confirm Sector Trends: Energy and healthcare weakness is broad-based. Don't fight the sector rotation.
• Watch Earnings Proximity: SNX reports in 22 days, MMM in 34 days—be mindful of event risk.
• Insider Activity Matters: SLGN (CEO bought) and CLS (director bought) show insider conviction despite mixed technicals.

Remember: crossovers are momentum signals, not fundamental calls. Use them as screening tools, then layer in your own research. In choppy markets, patience beats aggression.
