Our technical scanner continuously monitors every stock in the S&P 500 and Nasdaq 100, weighing dozens of indicators to surface the most compelling setups on both sides of the market. Each week we publish the names generating the strongest confluence of bearish signals — stocks where momentum, trend and volume indicators are all pointing in the same direction. Today, 16 October 2026, five names stand out as potential short candidates based purely on their technical profiles.
Important risk warning: Short selling involves risks that are materially different from — and often greater than — those of holding a long position. Losses on a short trade are theoretically unlimited, margin requirements can change at short notice, and stocks can gap sharply higher on news or short squeezes. The information below is for educational purposes only and should never be treated as a recommendation to sell any security short. Always size positions carefully and use appropriate risk-management tools.
1. Leidos (LDOS) – 13 technical sell signals
Price: $133.78 | Daily change: -3.88%
View the full technical analysis of Leidos
Leidos tops today’s bearish scan with 13 sell signals against only 3 bull signals, a notably lopsided reading. The defence and technology contractor has seen its share price slide meaningfully over the past year, and a nearly 4% single-day decline on 16 October underlines the current selling pressure. From a purely technical standpoint, momentum indicators, moving-average crossovers and volume patterns all appear to be pointing downward simultaneously.
Fundamentally, the picture is more nuanced. Analysts at Jefferies trimmed their price target on the stock in July, and recent commentary from Simply Wall St. suggests the shares may already be trading below fair value even as underlying earnings have held up reasonably well. Leidos has also been active on the partnership front, launching an AI-driven defence platform called Parcata in collaboration with DHL and teaming up with The Modern Data Company on federal AI infrastructure. The closure of its security screening joint venture in Australia adds a degree of operational uncertainty.
For technically oriented traders, the bear-signal dominance is striking, but would-be shorts should be mindful that any positive earnings surprise or contract announcement could trigger a swift reversal. The gap between the technical weakness and the apparently solid fundamentals makes this a higher-risk short setup than the raw signal count might suggest.
2. Omnicom Group (OMC) – 13 technical sell signals
Price: $81.76 | Daily change: -5.03%
View the full technical analysis of Omnicom Group
Omnicom Group shares fell more than 5% on 16 October, the sharpest single-day decline among today’s five candidates, and the technical scanner flags 13 bearish signals against 6 bullish ones. The advertising giant has broadly underperformed the wider communications services sector over the past year, and the technical deterioration appears to be accelerating rather than stabilising.
From a news perspective, the stock’s five-year total return of roughly 38% has left some analysts questioning whether the valuation has become stretched relative to the company’s growth trajectory. Omnicom’s return on equity has been flattered by a meaningful debt load, which introduces financial-leverage risk should advertising markets soften. The company has signalled a strategic pivot towards AI-driven marketing solutions, but it remains to be seen whether that transformation will be sufficient to re-rate the stock.
The relatively higher bull-signal count of 6, compared with only 3 for the top-ranked names, suggests that not every indicator has turned fully negative, so the bearish case is not entirely clean. Traders considering a short position should be aware that any improvement in the broader advertising market, or a well-received strategic update from management, could cause a rapid reversal in a stock that has already pulled back considerably.
3. Palo Alto Networks (PANW) – 13 technical sell signals
Price: $328.48 | Daily change: -9.28%
View the full technical analysis of Palo Alto Networks
Palo Alto Networks is today’s most dramatic mover, shedding more than 9% in a single session. The cybersecurity leader also registers 13 bearish technical signals and only 3 bullish ones. Even after this sharp drop, the stock remains elevated following an extraordinary year-to-date gain of approximately 125%, which means valuation concerns are far from resolved and may continue to weigh on sentiment.
Recent news flow has been a mixed bag. The company joined Anthropic’s Critical Infrastructure Defence Programme as a founding partner, signalling its ambition in the AI-security space, and a partnership announcement at Black Hat USA 2026 attracted fresh attention. However, the stock had already begun to retreat from its September highs — a close near $374 in late September gave way to the sharp selling seen this week — suggesting that positive news flow has been insufficient to sustain the prior price levels.
For technically focused traders, a 9% single-day decline on high volume is a meaningful deterioration, and the signal count confirms broad-based weakness across multiple indicator families. That said, PANW operates in a structurally growing market and any evidence of resilient subscription revenues or an upside earnings pre-announcement could quickly reverse the technical damage. The risk-reward profile of shorting a high-momentum name after a large single-day drop deserves careful consideration.
4. Autodesk (ADSK) – 12 technical sell signals
Price: $241.73 | Daily change: -2.41%
View the full technical analysis of Autodesk
Autodesk joins the list with 12 bearish signals and just 3 bullish ones. The 3D design and engineering software company has endured a difficult few months, with shares declining roughly 23% from their late-August peak before a partial recovery — a decline steep enough to have prompted several analysts to revisit whether the stock now offers value. The technical picture has nonetheless remained weak throughout.
The fundamental backdrop offers some context for the weakness. In late August, management issued full-year earnings guidance whose midpoint came in below analyst forecasts, which acted as a catalyst for renewed selling. The company has since promoted its agentic AI capabilities as a longer-term growth driver, and several commentators have argued that the current valuation — trading at a forward price-to-earnings multiple well below the stock’s historical average — may represent a mispricing. Whether those arguments gain traction with the broader market is a separate question.
Technically, the persistent inability to reclaim lost ground despite some stabilisation attempts is a concern for bulls and potentially encouraging for bears. However, with multiple analysts framing the stock as meaningfully undervalued and the sell-off already well advanced, shorting at these levels carries the risk of fighting against improving fundamental sentiment. Strict risk management is essential.
5. Constellation Brands (STZ) – 12 technical sell signals
Price: $129.35 | Daily change: -0.98%
View the full technical analysis of Constellation Brands
Constellation Brands rounds out the list with 12 bearish signals and 6 bullish ones. The maker of Corona and Modelo beers has been a persistent underperformer relative to the consumer defensive sector over an extended period, and the technical scanner reflects this sustained downtrend. Despite a modest daily decline of under 1%, the accumulated weakness across trend, momentum and breadth indicators remains notable.
The news narrative has been one of operational resilience coupled with share-price disappointment. The company generated solid free cash flow and maintained reasonable earnings in recent quarters, yet the stock has lagged peers by a wide margin. Earlier in the year, Citi upgraded the stock to a Buy rating, citing its undervalued status among defensive names, suggesting there is meaningful fundamental support at current levels. At the same time, sales growth has been harder to come by, raising questions about volume trends in the beer segment.
The relatively high bull-signal count of 6 means the technical picture is not uniformly negative, and the modest daily move today does not convey the kind of acute selling pressure seen elsewhere on this list. Shorts should be especially cautious given the defensive nature of the business, the Citi upgrade earlier in 2026, and the strong free-cash-flow generation, all of which could attract value-oriented buyers and limit further downside.
