EverHint Signal — EMA10 × EMA30 Crossover — December 09, 2025

What This Signal Is (Quick)

The EMA10 × EMA30 crossover looks for fresh shifts in short-term momentum versus the intermediate trend:

• Buy signal (EMA10_x_EMA30_Buy) – today’s close pushed the 10-day EMA above the 30-day EMA. That suggests short-term momentum is now outrunning the medium-term trend and may be starting a new upswing.
• Sell signal (EMA10_x_EMA30_Sell) – today’s close pulled the 10-day EMA below the 30-day EMA. That flags weakening momentum and potential trend exhaustion or reversal.

Because both averages are exponential, the setup reacts faster than slow, long-window crossovers. That makes it better suited for 1–4 week swing trades, but also more vulnerable to whipsaws when markets chop sideways rather than trend cleanly.

Everything here is built as an experimental scanner – it’s meant for idea generation, back-testing, and education, not as a stand-alone “buy/sell” system.

How We Ranked Today (Reader Version)

For today’s report (signal date 2025-12-09):

• We split signals into Buy (EMA10 crossing up through EMA30) and Sell (EMA10 crossing down through EMA30).
• Ranking logic
  • Buy side: sorted by RSI(14), lowest to highest – the idea is to surface crossovers where momentum turns up from relatively cooler levels first.
  • Sell side: sorted by RSI(14), highest to lowest – highlighting names where downside crossovers are appearing from more extended conditions.
• On top of price/RSI we overlay:
  • Insider net flow (90 days) – open-market purchases minus sales by insiders (P and S codes only).
  • Days → earnings – how close the next earnings event is (shorter windows often mean extra volatility).
• Signals are not buy or sell recommendations. They are a structured watchlist you can plug into your own thesis, risk rules, and back-tests.

Today’s counts:

• 61 buy-side crossovers, 35 sell-side crossovers (96 total).
• Roughly two-thirds of buy signals (40/61) fired above the 200-day simple moving average; 21/61 are still below.
• On the sell side, the split is more balanced: 19/35 above and 16/35 below their 200-day trend.

📈 Buy-Side Signals (Top 10 by RSI, most “cool” first)

Field notes – buy side

• ESLT, BTU, TEL, FTNT, VSAT, VIST, BIDU – a mix of defense, energy, tech and China-internet names with crossovers triggered from mid-50s RSI rather than deeply oversold territory. These look more like trend-continuation pivots than washed-out reversals.
• YOU, IDR – both show meaningful recent insider selling (negative net flow), so any bullish thesis here should be extra picky about risk and time horizon.
• Earnings proximity – several names (BTU, TEL, FTNT, VSAT) sit in the ~50–60 day window to earnings; closer-in events (inside 30 days) would typically call for tighter risk controls on new swing entries.

📉 Sell-Side Signals (Top 10 by RSI, most extended first)

Recent headlines snapshot (sell-side names with fresh news)

• AIR – Multiple press releases around new and extended distribution agreements plus an upcoming earnings date in early January, keeping the news flow active into a fresh downside crossover.
• BR – Recent coverage blends post-earnings performance commentary, platform/product updates, and institutional position changes, suggesting the trend is being watched closely by both fundamental and quant players.

(If you’re tracking any of these names, it’s worth reading the underlying articles in full for proper context before acting.)

Field Notes – How to Read These Metrics

• RSI(14)
  • Around 50 is “neutral” momentum.
  • Above 70 is often viewed as stretched on the upside; below 30 as stretched on the downside.
  • In this report, most crossovers are happening from mid-range RSI, which often means trend continuation rather than violent mean-reversion setups.
• Market Cap
  • We show caps in billions or millions to give a quick sense of size and institutional interest.
  • Larger names (e.g., TEL, FTNT, BR, VLTO) generally have tighter spreads and deeper options markets than micro-caps like IDR.
• Insider Net (USD, 90 days)
  • Positive = net buying (insiders accumulating shares).
  • Negative = net selling.
  • In today’s top lists, the larger non-zero flows (YOU, IDR, MMS, TDS) are net sellers, which is a yellow flag if you’re leaning strongly into the crossover signal alone.
• Days → Earnings
  • < 7 days: event risk is very high; price can ignore technicals entirely around the print.
  • 7–30 days: volatility often starts to pick up as positioning builds.
  • > 30 days: earnings are in the background, so technicals may have more room to play out.
• Above vs below the 200-day SMA
  • Above 200-day = primary trend up; crossovers tend to be continuation or shallow-pullback entries.
  • Below 200-day = primary trend down or repairing; crossovers can be sharper but also more prone to failure.
  • Today most buy signals are in the “trend-up” bucket, while sell signals are split more evenly.

Vlad’s Take (EverHint)

On 2025-12-09, the macro backdrop was mixed but not stressed:

• S&P 500 finished essentially flat (about -0.00%), the Dow slipped roughly -0.34%, while the Nasdaq gained about +0.31% – a small tilt toward growth and tech leadership.
• Small-caps (Russell 2000) outperformed with roughly +0.42%, a mild risk-on breadth signal beneath the surface.
• The VIX closed near 16.9, up modestly on the day but still in the normal volatility band (not panic, not euphoric calm).
• The 10-year yield hovered around 4.18%, slightly higher on the session – just enough to keep a bit of pressure on long-duration growth stories without dominating the tape.
• In crypto, Bitcoin advanced around +2.6% and Ethereum popped roughly +6.5%, a clear sign that speculative risk appetite remains alive.

In that context, EMA10 × EMA30 crossovers look like a classic stock-picking tool inside a sideways-to-up market: not every breakout will run, but the environment is still receptive to tactical swings, especially where trends are already aligned above the 200-day. For my own process, I’d:

• Treat buy signals above the 200-day (e.g., TEL, FTNT, VIST, BIDU) as candidates for staggered entries – scale in over 2–3 tranches instead of going all-in on the first breakout close.
• View sell signals with high RSI and insider selling (MMS, TDS) as useful risk-reduction alerts: maybe tighten stops, trim, or at least stop adding until the trend settles.
• Be extra careful around names with short earnings windows (inside ~30 days), where a good technical setup can still be derailed by a single headline.

Risk management is still the main edge: position sizing, pre-defined exits, and accepting that even a clean crossover can and will fail.
