Each trading day, our technical scanner evaluates hundreds of S&P 500 and Nasdaq 100 constituents against a broad set of indicators — momentum, trend, volume and mean-reversion signals among them. Stocks that accumulate a high number of bearish signals relative to bullish ones rise to the top of our short-candidate watchlist. Below are the five names generating the strongest technical sell signals on 13 August 2026.
Important risk warning: Short selling involves risks that go well beyond those of a standard long position. Losses on a short trade are theoretically unlimited, margin requirements can increase at short notice, and a sudden positive catalyst can trigger a rapid short squeeze. The names below are identified purely on the basis of technical signals; they are not recommendations to sell short. Always conduct your own due diligence and consult a qualified financial adviser before acting.
1. Corteva (CTVA) – 12 technical sell signals
Price: $75.53 | Daily change: -1.23%
View the full technical analysis of Corteva
Corteva leads today’s bearish watchlist with 12 sell signals against just 4 bull signals — the widest technical imbalance in today’s screen. The agricultural sciences company did report second-quarter earnings that modestly exceeded consensus expectations in late July, with per-share earnings ticking up year-on-year. At first glance, that would appear to support the bulls, but the market’s reaction has been cautious, and the stock has drifted lower in subsequent weeks.
Part of the hesitation centres on valuation. Despite the earnings beat, several analysts have noted that the shares already trade at a premium to sector peers, leaving limited margin for error. The costs associated with Corteva’s ongoing corporate separation and its investment in innovation pipelines add further execution risk to an otherwise constructive fundamental story. Bank of America has maintained a constructive stance and raised its price objective, yet even that endorsement has not been enough to arrest the technical deterioration visible on the charts.
With momentum indicators weakening and the stock now sitting notably below its recent highs, the technical picture suggests near-term selling pressure remains dominant. Bears will be watching closely for any break of key support levels, while bulls will need a catalyst beyond the earnings beat to reassert control.
2. Allstate (ALL) – 11 technical sell signals
Price: $255.84 | Daily change: -2.44%
View the full technical analysis of Allstate
Allstate stands out not only for its 11 bearish technical signals but for the complete absence of any bull signals — a relatively rare occurrence in our daily scan. The insurer has delivered an impressive multi-year return for shareholders, and its most recent quarterly results benefited from lower catastrophe losses and an improved combined ratio. However, analysts at Seeking Alpha and elsewhere have raised questions about whether that level of operating performance is repeatable over the medium term.
The insurer’s earnings picture is described as mixed: while premium income and investment returns have trended positively, the outlook for quarterly earnings has been more uncertain. Catastrophe exposure is an ever-present variable in property and casualty insurance, and any uptick in weather-related claims could weigh significantly on results. Legal risks have also been flagged by commentators as a factor that could pressure the valuation, even if the stock appears attractively priced on certain earnings-based metrics.
Today’s sharp daily decline of nearly 2.5% compounds the technical weakness already apparent in the scanner. With no offsetting bullish signals detected, the charts point to sustained distribution. Short sellers should nonetheless remain mindful that any favourable catastrophe season update or positive reserve development could quickly reverse momentum.
3. Aon plc (AON) – 11 technical sell signals
Price: $352.36 | Daily change: -1.15%
View the full technical analysis of Aon plc
Professional services and risk advisory firm Aon shares the 11-signal bear count with Allstate and Cincinnati Financial, though it retains three bullish technical signals — suggesting the bearish pressure, while meaningful, is not as absolute. Fundamentally, Aon attracted positive analyst attention earlier in 2026 following an earnings beat, with several institutions lifting their price objectives. TD Cowen remained constructive on the stock even while acknowledging pricing headwinds and the evolving impact of artificial intelligence on the insurance and advisory landscape.
Aon made headlines earlier in the year when it announced what it described as the first-ever stablecoin premium payment, underlining management’s willingness to pursue innovation. While such initiatives can generate positive sentiment, they also introduce operational and regulatory uncertainties that some investors may view as a distraction from the core business. Hedge funds have reportedly held positions in Aon as a value-oriented play, though more recent price performance has lagged the broader financial sector on certain timeframes.
Despite the constructive fundamental backdrop, the technical signals have deteriorated noticeably. Today’s decline of over 1% adds to a pattern of weakening momentum. Investors considering a short position here should weigh the fact that analyst sentiment remains broadly supportive, which increases the risk of a rapid re-rating should upcoming data surprise to the upside.
4. Cincinnati Financial (CINF) – 11 technical sell signals
Price: $172.47 | Daily change: -0.43%
View the full technical analysis of Cincinnati Financial
Cincinnati Financial rounds out a notable cluster of insurance-related names in today’s bearish scan, which may reflect broader sector-level headwinds rather than company-specific issues alone. The property and casualty insurer delivered a second-quarter earnings miss in late July that was fairly significant — reported earnings per share fell well short of consensus and also declined materially year-on-year. Revenues also disappointed, adding to the negative tone.
The stock had previously enjoyed a solid run in early 2026, reaching a 52-week high and outpacing the S&P 500 over a six-month window. However, the Q2 miss appears to have acted as a turning point, with the shares retreating from those highs and now sitting at $172.47 — a meaningful step down from the levels seen in June and early July. The removal of CINF from the Russell 1000 Dynamic index earlier in the year may have reduced passive demand for the shares, adding a structural overhang.
Today’s modest daily decline of 0.43% may look contained in isolation, but the accumulation of 11 bearish technical signals suggests a more persistent trend of selling pressure beneath the surface. Bears will look for continued follow-through from the earnings miss, while bulls may point to the company’s long dividend history as a floor of support.
5. Regency Centers (REG) – 11 technical sell signals
Price: $75.74 | Daily change: -0.11%
View the full technical analysis of Regency Centers
Regency Centers, a Jacksonville-based retail-focused real estate investment trust, closes today’s list with 11 bearish signals against 5 bullish ones — the highest bull count among the five candidates, which tempers the bearish conviction somewhat. The REIT owns and operates grocery-anchored shopping centres, a segment that has historically demonstrated resilience through economic cycles due to the necessity-driven nature of its tenant base.
Analyst coverage has been broadly supportive in recent months, with Scotiabank raising its price target in the spring and commentary from Simply Wall St suggesting the shares may have been offering reasonable value at prices somewhat above current levels. Year-to-date performance has at various points outpaced real estate sector peers, yet the stock has pulled back from those relative highs and now trades at a slight discount to where several valuation analyses placed fair value.
The technical picture tells a story of fading momentum in what has otherwise been a defensively positioned name. The near-flat daily move today masks the cumulative weight of the bearish indicator count. For short sellers, the relatively higher bull signal count and the supportive analyst community represent genuine risks; any positive update on occupancy rates, lease renewals or distribution coverage could quickly draw buyers back in. This is arguably the most technically ambiguous of the five candidates on today’s list.
