Our technical scanner runs daily across the S&P 500 and Nasdaq 100, measuring a broad range of momentum, trend and volatility indicators to identify stocks showing meaningful clusters of bullish or bearish signals. Today, 5 October 2026, we turn the spotlight on the short side — stocks where bearish technical signals significantly outnumber bullish ones, suggesting potential further weakness ahead. Short candidates are stocks that technically inclined traders may consider selling short, anticipating a price decline.
Important risk warning: Short selling carries substantially greater risk than buying stocks. Losses on a short position are theoretically unlimited, since a stock’s price can rise indefinitely. Short squeezes, unexpected positive news and thin liquidity can all cause rapid, sharp moves against a short position. Always size positions carefully, use stop-loss orders and ensure short selling is appropriate for your personal risk tolerance and financial situation.
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 screen with 13 sell signals against just 3 bull signals, and a sharp single-session drop of nearly 4% underscores the technical deterioration. The stock has already been flagged as a market laggard, trailing broader indices over the past year despite analysts maintaining a cautiously constructive view on the business itself.
On the fundamental side, the picture is admittedly more nuanced. The company reported record second-quarter revenue of $4.56 billion in August, representing 7% year-over-year growth, and subsequently raised its full-year guidance — developments that initially sent shares higher by double digits. More recently, Leidos has announced a partnership focused on federal AI data infrastructure and launched an AI-driven defence platform called Parcata in collaboration with DHL, signalling continued strategic momentum.
The disconnect between positive business newsflow and weakening price action is itself a cautionary technical signal — it may suggest that good news has already been priced in, or that institutional sellers are using strength to reduce exposure. Jefferies has also trimmed its price target on the stock, adding a layer of analyst caution. Bears will note the heavy sell-signal cluster; bulls will point to robust fundamentals. As always, the technicals and fundamentals do not always move in lockstep.
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 is the second name on our bearish scan, matching Leidos with 13 sell signals, but standing out with the sharpest daily decline in our top five — a fall of more than 5%. The advertising and marketing services giant has a somewhat mixed recent record: media account wins have supported sentiment at times, yet a second-quarter earnings report in late July revealed a notable miss on profitability, which triggered a 3.7% single-session sell-off at the time.
The company completed its acquisition of Interpublic Group earlier this year, a transformative deal that management argues will unlock meaningful cross-selling opportunities and expand its artificial intelligence capabilities across client campaigns. Analysts at Zacks have adopted a neutral holding stance, acknowledging these longer-term opportunities while flagging integration risks and near-term earnings uncertainty as factors that warrant patience.
From a valuation perspective, one analysis flagged the stock as appearing stretched relative to its cash flow generation, even as total returns over the past five years have been solid. Today’s sharp price drop, combined with 13 bearish technical signals and only 6 bullish ones, suggests the market is currently more focused on near-term risks than longer-term strategic optionality. Traders considering a short position should remain alert to any positive surprise from ongoing media account wins or integration progress.
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 the most dramatic mover on today’s list, falling more than 9% in a single session — a stark reversal for a stock that had gained approximately 21% in the month following its last earnings report and was trading as high as $374.74 as recently as 26 September. Today’s sell-off brings 13 bearish technical signals into sharp focus, with only 3 bullish counterweights, making the technical picture the most lopsided in our top five alongside LDOS.
The fundamental debate around Palo Alto is particularly intense. The company’s platformization strategy — bundling multiple cybersecurity products into integrated enterprise platforms — has been driving larger deal sizes and stronger customer retention, with AI security integrations involving Anthropic, OpenAI and NVIDIA adding further product appeal. Analysts have re-rated the stock higher on the back of these developments, and the business underpinnings remain strong.
However, a prominent Seeking Alpha analysis published just days ago argued that the valuation has become disconnected from underlying organic growth, which is described as normalising, and raised concerns about rising merger-and-acquisition risk at elevated multiples. For technically oriented traders, a near-10% daily decline following a strong run-up is a classic signal of distribution — potential institutional selling into retail strength. Shorts should be aware that high-conviction growth stocks like PANW can recover swiftly on any positive catalyst.
4. Autodesk (ADSK) – 12 technical sell signals
Price: $241.73 | Daily change: -2.41%
View the full technical analysis of Autodesk
Autodesk enters the bearish scan with 12 sell signals and just 3 bullish ones, and today’s 2.4% decline is part of a broader downtrend that has seen the stock shed approximately 23% from its late-August high. At current levels, a hypothetical $10,000 invested at the peak would be worth roughly $7,700 — a painful drawdown that reflects a significant shift in market sentiment toward the design software company.
The reasons behind the decline are not entirely clear from recent news, which has been largely technical or market-wide in character rather than company-specific. Rising bond yields have weighed on growth and technology stocks more broadly, and Autodesk, as a software business trading on an elevated earnings multiple, is naturally sensitive to changes in the interest rate environment. Broader market weakness on days when yields spiked has coincided with pronounced moves lower in ADSK.
Some analysts see the pullback as a potential buying opportunity, arguing that Autodesk’s dominant position in architecture, engineering and construction software provides durable revenue visibility. However, from a purely technical standpoint, a stock that has lost nearly a quarter of its value in five weeks while generating 12 bearish signals warrants respect. Prospective shorts should note that the stock has already experienced a significant decline, which increases the risk of a mean-reversion bounce.
5. Constellation Brands (STZ) – 12 technical sell signals
Price: $129.35 | Daily change: -0.98%
View the full technical analysis of Constellation Brands
Rounding out today’s list is Constellation Brands, the beverages group behind premium beer brands, which registers 12 bearish technical signals against 6 bullish ones. The daily price move is the most modest in our top five — a decline of just under 1% — but the accumulation of sell signals across multiple indicators tells a more cautious story about the stock’s underlying technical health.
The near-term focus for Constellation Brands is its upcoming second-quarter fiscal 2027 earnings release, which was flagged as imminent as of 4 October. Analyst expectations heading into the report will be a key driver of short-term price action, and any meaningful miss — particularly on volume trends in its core beer segment — could accelerate the technical weakness already visible in the scan data. Equally, a beat could trigger a sharp recovery and cause pain for short positions.
Constellation has faced a more challenging consumer environment in recent quarters, with premium beverage spending showing signs of pressure as households remain cautious about discretionary expenditure. The 6 bullish signals that sit alongside the 12 bearish ones suggest the picture is not entirely one-sided, and the stock’s relatively modest daily move implies that sellers have not yet taken full control. Traders considering a short position ahead of earnings should be especially mindful of the event risk involved — earnings releases are among the most common triggers for short squeezes.
