Our proprietary technical analysis scanner runs daily across the full S&P 500 and Nasdaq 100 universes, scoring each stock on a broad range of momentum, trend, and oscillator indicators to identify potential short candidates. For 29 September 2026, the five names below have generated the highest concentration of bearish technical signals relative to bullish ones. A short candidate is a stock whose technical picture suggests the price may continue to decline, making it a potential candidate for a short-selling strategy.
Important risk warning: Short selling carries significantly elevated risks compared with buying stocks. Losses on a short position are theoretically unlimited, margin requirements can be demanding, and a stock can be subject to a short squeeze at any time. The analysis below is purely technical in nature and does not constitute investment advice. Always conduct your own due diligence and consider your risk tolerance carefully before initiating any short position.
1. Leidos (LDOS) – 13 technical sell signals
Price: $133.78 | Daily change: -3.88%
View the full technical analysis of Leidos
Leidos sits at the top of today’s bearish leaderboard with 13 sell signals against just 3 bull signals, and a sharp single-session decline of nearly 4% underlines the technical deterioration. The stock has been a persistent underperformer relative to the broader market over recent months, with analysts noting that it has lagged behind even as the S&P 500 pushed higher at various points through the summer.
On the fundamental side, the picture is more mixed. The company secured a meaningful $301 million, five-year Army cybersecurity contract in late August, which analysts viewed positively for backlog visibility and AI-enabled revenue streams. However, contract wins alone have not been sufficient to arrest the stock’s broader downtrend, and recent session data shows continued relative weakness even on days when the index has recovered.
From a technical standpoint, the combination of 13 bearish indicators and only 3 supportive signals suggests that selling pressure remains well entrenched. Potential short sellers should note that any renewed contract announcement or positive earnings revision could trigger a swift reversal, so position sizing and stop-loss discipline are especially important here.
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 shed more than 5% in a single session on 29 September, a substantial move that aligns with its 13 bearish technical signals. The advertising conglomerate has already been noted as an underperformer within the communications services sector over the past year, and today’s sharp decline only reinforces that picture. A five-year total return that some analysts have described as modest relative to peers suggests the stock has struggled to generate sustained momentum.
The broader advertising industry continues to navigate structural headwinds, including shifts in digital marketing spend and competitive pressure from technology platforms. While Omnicom has highlighted strategic repositioning efforts and interest in AI-driven transformation, these initiatives have yet to translate into the kind of earnings acceleration that would attract fresh buyers at scale.
With 13 sell signals and 6 bull signals, the technical balance is clearly tilted to the downside, though the slightly higher bull count compared with some other names on this list is worth noting. Short sellers should remain alert to the possibility that a positive earnings surprise or a significant client win could rapidly change market sentiment and squeeze short positions.
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 arguably the most striking entry on today’s list, having fallen more than 9% in a single session while simultaneously carrying 13 bearish technical signals. That kind of sharp single-day drawdown can itself generate additional technical sell triggers, so the score may understate the severity of the current technical breakdown if the weakness persists.
What makes this candidate particularly nuanced is the bullish fundamental backdrop. In the days immediately prior to this sell-off, multiple analysts raised their price targets on the stock, and reports highlighted the company’s AI security product suite as a potential driver of accelerated growth. BTIG reiterated a buy rating with an increased target just a day before the decline, citing specific platform developments. This disconnect between improving analyst sentiment and severe technical weakness is a notable red flag and may point to broader risk-off rotation rather than company-specific deterioration.
For short sellers, this is one of the higher-conviction technical setups on the list, but also one of the higher-risk trades. Cybersecurity remains a sector with strong secular tailwinds, and any renewed buying from institutional investors or positive data points could result in a rapid and painful reversal for those holding short positions.
4. Autodesk (ADSK) – 12 technical sell signals
Price: $241.73 | Daily change: -2.41%
View the full technical analysis of Autodesk
Autodesk enters the list with 12 sell signals and only 3 bullish counterweights, reflecting a technical picture that has been deteriorating for some time. The design and engineering software company has endured a difficult period, with the stock having retreated meaningfully over the past five years according to recent commentary. A notable intraday drop of over 4% was recorded in late July, and the shares have continued to struggle to reclaim lost ground in the weeks that followed.
Valuation discussions around Autodesk have been mixed. Some analysts argue the stock appears inexpensive on a cash flow basis, while earnings-based metrics paint a less compelling picture. The company does operate in a sector with genuine long-term growth potential — construction and manufacturing technology adoption remains at relatively early stages — but that narrative has not been enough to stabilise the technical trend in recent months.
The lean bull signal count of just 3 against 12 bear signals leaves little ambiguity in the near-term technical outlook. That said, Autodesk’s subscription-based revenue model and recurring cash flows give it defensive characteristics that could attract buyers on weakness, so prospective short sellers should factor in the risk of a sharp snapback if sentiment shifts.
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 sell signals and 6 bull signals. While its daily decline of under 1% is the most modest of the five names, the stock’s broader technical deterioration has been sustained and significant. The shares struck a 52-week low in late September, a development that typically invites further technical selling as momentum traders exit and stop-loss orders are triggered below key support levels.
The fundamental picture has also been clouded recently. JPMorgan trimmed its price target on the stock in late September, reflecting expectations of softer near-term earnings. Analysts were anticipating weaker second-quarter results ahead of an early October earnings release, and that earnings uncertainty is an additional headwind to sentiment. Leadership changes, including a new chief supply chain officer for the beer division, add an element of operational uncertainty during an already challenging period.
Despite owning high-profile imported beer brands with strong consumer recognition, the company appears to be losing pricing and volume momentum in the current environment. The 6 bull signals do provide a modest counterbalance, and any upside earnings surprise relative to already-lowered expectations could trigger a sharp relief rally. Short sellers should keep a close eye on the earnings release and manage risk accordingly.
