Two of Tradestie's backtest-validated scanners — SOXX Bullish and SPY Bullish — simultaneously flagged ON Semiconductor (NASDAQ: ON) today, with the stock sitting in a multi-month base near $71 and options market positioning tilting bullish. With 14 analyst buy ratings, a consensus price target of $100, and a supply-chain bottleneck score of 7–8/10 in both the semiconductor and Physical AI graphs, the setup warrants a disciplined look — not as a breakout chase, but as a base-building entry with clearly defined risk.
The Signal
Both of Tradestie's systematic scanners triggered on ON as of November 4, 2026. These are not momentum-chasing signals — by design, they identify stocks in consolidation or early bottoming phases, not names already extended to the upside.
- SOXX Bullish scanner: 57.5% of entries were positive after 20 trading days, with a median excess return vs. SPY of +1.90%, across 678 backtested entries. This is the stronger signal of the two.
- SPY Bullish scanner: 52.4% of entries positive after 20 trading days, with a median excess return vs. SPY of +0.37%, across 966 backtested entries.
Neither signal guarantees a rally — the SOXX Bullish scanner is positive less than 6 times in 10, and the SPY Bullish scanner barely clears a coin flip. What they do offer is a statistically documented edge under defined conditions. The signal fired with just 4 Reddit mentions on ON today, well within its normal baseline — this is not a retail hype event. That matters: historically, scanner hits that arrive with low social noise carry a cleaner signal-to-noise ratio than those surfing a momentum crowd.
The Setup: A Deep Base, Not a Breakout
ON is trading at $71.36, sitting below its 20-day SMA of $74.46 and its 50-day SMA of $74.66. The 5-day trend is down 5.2% and the 20-day trend is down 10.1%, which on the surface looks discouraging — but this is exactly the type of configuration these scanners are designed to surface. The 100-day trend is down 43.3%, meaning ON has been in a prolonged correction from significantly higher levels. The stock is now in what the trendline model classifies as above its statistical mean within that downtrend channel — a subtle but meaningful signal that selling pressure may be exhausting.
The RSI sits at 43.8 — not yet oversold, but not extended either. MACD is bearish on the intermediate timeframe. This is not a stock that has bottomed cleanly; it is one that may be establishing the right side of a base. The scanner's historical edge is built precisely on entries that look uncomfortable.
The fundamental backdrop provides useful context. The street consensus for FY2026 EPS sits at $3.28, implying ~40% year-over-year growth. FY2027 estimates step up further to $4.68, another 43% forward growth. Revenue is expected to grow from roughly $6.59 billion this year to $7.53 billion in FY2027. Critically, estimate revision momentum over the last 30 days is strongly positive: 43 upward revisions vs. 10 downward — analysts are raising numbers, not cutting them, while the stock trades near its lows.
What the Options Market Says
The options flow score for ON comes in at 68 out of 100, the strongest sub-score in the overall composite rating. The aggregate flow signal is classified as mixed, but the gamma wall positioning tells a more directional story.
The call wall sits at the $80 strike with 72,225 contracts of open interest. The put wall sits at the $60 strike with 64,973 contracts. This $60–$80 corridor is where dealer hedging activity is concentrated — price will tend to be magnetized within this range and face resistance at its edges. With ON currently at ~$71, it sits almost exactly in the middle of that corridor, with roughly equal distance to both walls.
The overall gamma bias reading is bullish. That does not mean the stock is about to rip; it means the net dealer positioning currently creates a mild upside tailwind from hedging flows as price holds above the put wall. If ON were to drop toward $60, that dynamic would shift materially.
Supply-Chain Position: The Overlooked Structural Case
ON Semiconductor occupies a genuinely differentiated position in the semiconductor supply chain — one that most price-action focused coverage ignores. In Tradestie's supply-chain knowledge graph, ON scores 7/10 on the semiconductor graph and 8/10 on the Physical AI graph, both classified as oligopoly moat. This matters because bottleneck scores measure how substitutable a company is — and ON, in power semiconductors and silicon carbide, is not easily replaced.
ON's core products span Power Management ICs, Silicon Carbide (SiC) semiconductors, Image Sensors, and Intelligent Power Solutions. Its key customers include Tesla (TSLA), Apple (AAPL), Ford (F), and General Motors (GM) — a mix of EV and consumer electronics that gives it direct exposure to two of the decade's largest electrification themes. Its competitors — Texas Instruments (TXN), STMicroelectronics (STM), Infineon (IFX), and NXP Semiconductors (NXPI) — are substantial, but the SiC market in particular remains concentrated enough that ON, TSLA's primary SiC supplier, retains meaningful pricing leverage.
ON's high Physical AI exposure rating (scored "high" in the Physical AI graph) reflects its role supplying power and sensing components to autonomous systems, EVs, and intelligent edge devices. As Physical AI — robotics, autonomous vehicles, smart manufacturing — scales from pilot to production, the power semiconductor layer is a structural bottleneck. ON sits squarely in that chokepoint.
Key Levels to Watch
| Level | Price | Significance |
|---|---|---|
| Call Wall (Resistance) | $80.00 | 72,225 contracts OI; ceiling for near-term dealer-driven price action |
| 20-Day SMA | $74.46 | First overhead resistance; reclaiming this would confirm base progress |
| 100-Day Resistance | $73.17 | Trendline resistance from the 100-day downtrend channel |
| Current Price | $71.36 | Near mid-corridor between put and call walls |
| 20-Day Support | $68.61 | Key structural floor; loss of this level changes the thesis |
| Put Wall (Floor) | $60.00 | 64,973 contracts OI; loss of this level would signal material deterioration |
| Analyst Mean Target | $100.00 | Street consensus; implies 37.7% upside from current levels |
What Would Invalidate This Setup
The setup rests on ON holding its structural support and the base-building thesis playing out over the next 20 trading days. Three specific conditions would invalidate it. First, a weekly close below $68.60 — the converging 20-day and 100-day support — would signal that sellers remain in control and the base has failed. Second, a breakdown through the put wall at $60 would represent a structural deterioration in options positioning and would likely trigger accelerated selling from dealer delta-hedging. Third, any reversal in the current estimate revision trend — specifically, net downward EPS revisions shifting negative after the 30-day trend of 43 upgrades vs. 10 downgrades — would remove the fundamental tailwind underpinning the thesis. EV demand softness from Tesla or GM, ON's two largest end markets, is the most plausible catalyst for such a revision turn.
Bottom Line
ON Semiconductor is not a momentum trade. Both scanner signals that fired today have documented hit rates below 60%, and the stock remains in a multi-month downtrend that has not yet definitively reversed. What the setup offers is a statistically backed entry into a base, with the SOXX Bullish scanner's 57.5% win rate and +1.90% median 20-day excess return as the primary quantitative anchor, supported by a structurally irreplaceable supply-chain position in SiC power and Physical AI, strongly positive estimate revisions, and bullish gamma positioning. If ON holds $68.60 and begins reclaiming the $74 SMA zone, the risk/reward tilts favorably toward the analyst consensus at $100. If it loses that floor, this article's thesis is off the table — and that is the accountability this tracking approach demands.
