Quick answer: A fresh technical screen of 3D-printing, semiconductor, medtech, and industrial-tech stocks shows Novanta (NOVT) posting the highest composite technical score (15) on the list, while a wave of chipmakers - including Lumentum (LITE, +13.63%), Viavi (VIAV, +12.27%), and Ciena (CIEN, +11.49%) - surged on heavy volume with "Golden Cross" buy signals. At the same time, five stocks flipped into "Strong Sell / Exit Now" territory, led by 3D Systems' distressed penny-stock peer Desktop Metal (DM) and CEVA Inc. (CEVA). Here's a full breakdown of the signals, what they mean, and which names are showing the strongest - and weakest - setups right now.

What Happened in Today's Screen
A broad technical scan covering additive manufacturing, medical devices, industrial software, semiconductors, and networking stocks shows a clear split-market pattern: chip and photonics names are breaking out on strong volume, while several previously beaten-down names are confirming downtrends and triggering sell signals.
Semiconductor equipment and optical names dominated the gainers list, with Lumentum (LITE) up 13.63%, Viavi Solutions (VIAV) up 12.27%, and Ciena (CIEN) up 11.49% - all three showing "Golden Cross" patterns (a bullish signal where the 50-day moving average crosses above the 200-day moving average).
Top-Scoring "Strong Buy" Stocks Right Now
The screener ranks each stock with a composite score from technical indicators including RSI, MACD, ADX trend strength, volume flow (OBV/MFI), and moving-average crossovers. Here are the highest-scoring names:
| Ticker | Price | Day Chg | Score | Signal | Trend | Golden/Death Cross |
|---|---|---|---|---|---|---|
| NOVT | $167.04 | -0.40% | 15 | Strong Buy | Trending | Golden Cross |
| PRLB | $90.80 | +0.39% | 13 | Strong Buy | Trending | Golden Cross |
| BFLY | $9.45 | +0.85% | 13 | Strong Buy | Trending | Golden Cross |
| GKOS | $186.63 | +2.54% | 13 | Strong Buy | Trending | Golden Cross |
| SITM | $680.52 | +2.01% | 13 | Strong Buy | Weak | Golden Cross |
| EMR | $163.80 | -0.35% | 13 | Strong Buy | Trending | Golden Cross |
| ZBRA | $378.37 | -1.22% | 13 | Strong Buy | Trending | Golden Cross |
| COHR | $355.64 | +8.24% | 13 | Strong Buy | Ranging | Golden Cross |
| MPWR | $1,425.01 | +1.63% | 13 | Strong Buy | Ranging | Golden Cross |
Novanta (NOVT), an industrial photonics and motion-control company, tops the list with the highest composite score. It's up nearly 9% over the past week and roughly 14% over the past month, trading just under its 52-week high with strong volume confirmation and a bullish DI crossover (+DI at 27.3 vs. -DI at 10.2).
Semiconductor Stocks Are Surging on Volume
Chip-sector momentum stood out across the screen, with several names posting double-digit single-day gains:
- Lumentum (LITE): +13.63% on the day, up 119.7% in historical volatility, trading well above both its 50-day ($816.89) and 200-day ($628.44) moving averages
- Viavi Solutions (VIAV): +12.27%, RSI at 55.4 (neutral), Stochastic at 96.1 (overbought)
- Ciena (CIEN): +11.49%, ADX at 20.0 indicating an emerging trend
- Coherent (COHR): +8.24%, one-week return of 8.35%
- Entegris (ENTG): +7.24%, RSI 61.2, week return 10.67%
- Teradyne (TER): +6.11%, three-month return of 12.36%
Most of these names are flashing "Overbought" readings on RSI or Stochastic %K, which the screener flags for "Tighten Stop" or "Take Profit" exit signals on names that have already run hard - a reminder that a strong breakout and a "buy at any price" signal are not the same thing.
Which Signals Actually Matter? A Quick Glossary
RSI (Relative Strength Index) measures whether a stock is overbought (above 70) or oversold (below 30) based on recent price momentum. A neutral RSI between 30–70 suggests room to run in either direction.
MACD Histogram shows momentum shifts. A positive, rising value (bullish) suggests upward momentum is building; a negative value (bearish) suggests the opposite.
Golden Cross vs. Death Cross:
- A Golden Cross happens when a stock's 50-day moving average crosses above its 200-day moving average - widely viewed as a long-term bullish signal.
- A Death Cross happens when the 50-day average crosses below the 200-day average - a longer-term bearish signal.
ADX (Average Directional Index) measures trend strength, not direction. A reading above 25 generally signals a strong trend (up or down); below 20 suggests a ranging, directionless market.
Risk/Reward (R:R) Ratio compares potential profit to potential loss on a trade setup. A 2:1 ratio or higher is generally considered more favorable; several setups on this screen show R:R below 1:1, flagged as "poor risk/reward" despite bullish signals.
Stocks Flashing Warning Signs
Not every setup on the screen is bullish. Five stocks triggered "Strong Sell" or bearish downtrend signals:
| Ticker | Price | Day Chg | Score | Signal | Exit Reason |
|---|---|---|---|---|---|
| DM | $0.03 | 0.00% | -12 | Strong Sell | Score -12, ADX confirms downtrend |
| CEVA | $30.44 | -1.27% | -10 | Strong Sell | Score -10, ADX 27 confirms downtrend |
| CDNS | $323.13 | -1.34% | -8 | Strong Sell | Monitor - downtrend active |
| SYM | $41.19 | -1.20% | -7 | Strong Sell | Monitor - downtrend active |
| ESE | $300.42 | +1.70% | -6 | Strong Sell | Monitor - downtrend active |
Desktop Metal (DM) stands out as the most extreme case, trading at just $0.03 with a 52-week decline of roughly 77% off its highs and a bearish MACD, RSI, and Death-Cross-adjacent structure. CEVA Inc., a semiconductor IP licensor, shows an oversold Stochastic reading (6.9) alongside a confirmed downtrend, with -DI (36.7) sharply exceeding +DI (19.5).
Featured Snippet: Quick-Answer Summary
What is the top technical stock signal today? Novanta (NOVT) currently shows the highest composite technical score (15) among the screened stocks, with a confirmed uptrend, Golden Cross, and bullish directional indicators.
Which stocks are overbought right now? Several names - including Zebra Technologies (ZBRA), Applied Digital-adjacent semiconductor names like Onto Innovation (ONTO), Coherent (COHR), and Lumentum (LITE) - show RSI or Stochastic readings above 80, a classic overbought signal that often precedes a pullback or consolidation.
Which stocks should traders watch for downside risk? Desktop Metal (DM), CEVA (CEVA), Cadence Design Systems (CDNS), Symbotic (SYM), and ESCO Technologies (ESE) all carry negative composite scores and confirmed downtrend readings on this screen.
Today's technical screen paints a picture of a semiconductor- and photonics-led rally running alongside pockets of real weakness in software, robotics, and legacy hardware names. Strong scores on names like NOVT, EMR, ZBRA, and MPWR reflect confirmed uptrends with volume support - but overbought readings across the chip sector suggest near-term chop is possible even within the broader bullish trend. On the flip side, DM and CEVA's breakdown signals are a reminder that not every stock is participating in the rally.
As always, technical scores reflect price and volume patterns only - they don't account for earnings, news catalysts, or company fundamentals. Treat this as one input among many, not a standalone trade signal.
