Each week our technical scanner sweeps the S&P 500 and Nasdaq 100, tallying the balance of bullish and bearish signals thrown up by a broad array of indicators — momentum oscillators, moving-average crossovers, volume studies and more. When bearish signals substantially outnumber bullish ones, a stock earns a place on our short-candidate watchlist. Today, 12 October 2026, five names stand out with particularly lopsided readings.
Important risk warning: Short selling is materially more dangerous than buying equities. Losses are theoretically unlimited, borrowing costs erode returns, and a single piece of positive news can trigger a sharp short squeeze. The names below are identified purely on technical grounds and do not constitute investment advice. Always size positions carefully and use appropriate risk controls.
1. Leidos (LDOS) – 13 technical sell signals
Price: $133.78 | Daily change: -3.88%
View the full technical analysis of Leidos
Leidos is one of the most technically deteriorated names on today’s list, carrying 13 bearish signals against just 3 bullish ones. The defence and government-technology contractor has been a consistent laggard relative to the broader market over the past year, a pattern noted by multiple analysts even as the company’s underlying earnings have remained reasonably solid. That divergence between fundamental stability and weak price action is itself a cautionary signal: the market appears to be pricing in risks that the headline numbers do not yet fully reflect.
On the news front, the closure of Leidos Australia’s security-screening joint venture drew attention in early October, introducing a layer of strategic uncertainty. Meanwhile, a price-target reduction from Jefferies over the summer underlined lingering questions about the company’s space-technology positioning. The launch of the AI-driven Parcata platform in partnership with DHL on UK defence contracts is an interesting development, but it has done little to arrest the share-price slide.
With the stock already down sharply on the session, short-sellers should be mindful that oversold conditions can produce sharp technical bounces, particularly in defence names where government-contract announcements can arrive without warning and move the stock quickly.
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 matches Leidos with 13 bearish signals, and today’s near-5% decline is a striking single-session move for an established large-cap advertising company. The stock has been a persistent underperformer within the communications-services sector over the past year, even as management has pursued an AI-driven strategic transformation designed to future-proof its agency model. That repositioning has yet to translate into meaningful price momentum.
Longer-term, Omnicom’s five-year total return of around 38% looks modest relative to broader market gains, and commentary from analysts has questioned whether current valuations adequately reflect the challenges facing the traditional advertising industry. The company’s return on equity is elevated, but a substantial portion is attributable to financial leverage rather than purely operational performance — a distinction worth keeping in mind when assessing the quality of those returns.
The advertising sector broadly faces headwinds from clients scrutinising marketing budgets in an uncertain macroeconomic environment. However, short-sellers should note that OMC is a dividend-paying, cash-generative business with a long operating history, factors that can attract value-oriented buyers and limit the downside on any given pullback.
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
Today’s most dramatic mover on our list is Palo Alto Networks, off more than 9% in a single session despite — or perhaps because of — a remarkable recent run. Reports from just days earlier described the cybersecurity leader surging roughly 26% over the preceding month and pressing against all-time-high territory near $432. That kind of parabolic move almost inevitably sets up a sharp reversal once momentum fades, and our scanner’s 13 bearish signals suggest the technical picture has turned decisively.
The broader cybersecurity sector has been buoyant, supported by strong demand signals and positive commentary from peers including Zscaler. Palo Alto itself launched its Unit 42 Continuous Frontier AI Defence subscription to positive industry reception, and several investment banks raised their price targets during the recent rally. However, the stock’s retreat from elevated levels is steep, and insider disposals — including a planned share sale by a senior executive — have attracted attention at a sensitive moment in the chart.
It is particularly important to exercise caution when shorting high-growth technology names in strong secular trends. Cybersecurity spending shows no structural signs of slowing, and any positive news — a large contract, an earnings beat or a sector catalyst — could produce a violent short squeeze from current levels.
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 bearish signals against just 3 bullish ones, and its chart tells an uncomfortable story for existing holders. The design-software specialist shed roughly 22-23% in the weeks following its most recent earnings release — one of the steeper post-results declines seen among large-cap software names in recent memory. While the stock has since recovered some ground from its intra-month lows, the technical damage from that sell-off remains visible across multiple timeframes.
The fundamental narrative is genuinely mixed. Several analysts have characterised the post-earnings drop as an overreaction, pointing to Autodesk’s asset-light business model, a meaningful free cash flow yield relative to the broader S&P 500, and what they see as an undemanding forward earnings multiple by historical standards. A leadership change at the helm of the architecture, engineering and construction division — with long-time executive Diana Colella taking the role — adds a degree of near-term uncertainty even as management pushes an AI and cloud-focused growth agenda.
Bears will argue that the sharp earnings-driven decline reflects genuine concerns about revenue growth sustainability. Contrarian bulls, however, are vocal about the valuation case. That contested narrative makes Autodesk a higher-risk short than its technical score might initially suggest.
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 most balanced reading among today’s five candidates, which is worth bearing in mind. The beer, wine and spirits company reported fiscal second-quarter results that beat revenue and earnings estimates, yet the stock still dropped in the aftermath, a classic sell-the-news reaction that underscores how demanding investor expectations have become. The core issue flagged by the market is weakening US beer depletion volumes, even as Modelo retains its position as the top-selling beer brand by dollar sales.
Management is actively trying to diversify and reinvigorate the portfolio. The recent acquisition of SpikedAde — a vodka-based, non-carbonated, low-calorie ready-to-drink brand — is a sign that the company is chasing the fast-growing RTD segment, citing strong recent growth for the brand. Whether bolt-on deals of this kind can meaningfully offset structural pressure on core beer volumes remains an open question.
The stock trades at a low double-digit earnings multiple, which provides some valuation support and gives potential short-sellers less margin for error. Analysts are divided on whether depletions data will stabilise; any evidence of a recovery there could reverse the technical weakness relatively quickly.
