Our technical scanner runs daily across the full S&P 500 and Nasdaq 100 universes, scoring each stock on a broad set of momentum, trend and oscillator indicators. Stocks with a high concentration of bearish signals and a low count of bullish ones rise to the top of our short-candidate watchlist. Today, 28 July 2026, we highlight the five names that generated the strongest technical sell signals in that combined universe.
Important risk warning: Short selling involves substantially greater risk than buying equities. Losses on a short position are theoretically unlimited, borrowing costs can be significant, and a stock can remain technically oversold for far longer than anticipated. The names below are flagged by our scanner as technically weak — they are not recommendations to sell short. Always size positions carefully and use appropriate risk controls.
1. C.H. Robinson (CHRW) – 16 technical sell signals
Price: $174.46 | Daily change: -15.11%
View the full technical analysis of C.H. Robinson
C.H. Robinson tops our bearish leaderboard this week with 16 sell signals against only 7 bull signals — a notably lopsided reading. The sheer scale of Tuesday’s decline underscores how rapidly sentiment has shifted for the freight and logistics giant, which had previously delivered an impressive multi-year run for patient shareholders.
The immediate catalyst for the share-price collapse appears to be a $604 million jury verdict handed down in a Texas lawsuit. News of the ruling sent the stock sharply lower in premarket trading on 25 July, and the broader third-party logistics sector followed suit, suggesting the market views the ruling as a potential precedent rather than an isolated event.
Compounding the legal overhang, CHRW had already been contending with soft freight demand and rising operating costs heading into its Q2 earnings report. While the company has been investing in AI-powered supply-chain tools — including its newly launched Lean AI Engineer platform — those longer-term initiatives do little to offset a near-term environment defined by legal liability uncertainty and weak freight pricing. The technical picture, with 16 bearish indicators firing simultaneously, reflects the magnitude of that fundamental shock.
2. West Pharmaceutical Services (WST) – 15 technical sell signals
Price: $331.25 | Daily change: -6.82%
View the full technical analysis of West Pharmaceutical Services
West Pharmaceutical Services scores 15 bearish technical signals against a mere 3 bullish ones, giving it one of the weakest bull-to-bear ratios on our entire scan. The stock dropped nearly 7% on the day, which is a considerable move for a healthcare packaging company that had, until recently, been building positive momentum.
The timing is notable. WST reported second-quarter results on 24 July, with sales climbing a healthy 13.8% year-on-year. Biologics packaging and high-value components were cited as key drivers, and management raised its full-year outlook. On the surface, those are constructive signals — yet the market’s negative reaction suggests investors may be questioning whether the valuation already reflected much of that optimism.
Analysts had flagged the stock as carrying above-average risk even before earnings, pointing to stretched multiples and execution sensitivity around the GLP-1 drug delivery growth narrative. A piece published earlier in July described three specific risk factors that could weigh on the share price, even as the six-month performance had comfortably outpaced the broader market. With technical indicators now firmly in bear territory, the divergence between operational momentum and price action warrants close attention.
3. Targa Resources (TRGP) – 13 technical sell signals
Price: $267.64 | Daily change: -6.28%
View the full technical analysis of Targa Resources
Targa Resources, a leading integrated midstream operator with significant Permian Basin exposure, appears third on our list with 13 sell signals and only 2 bull signals. The stock shed more than 6% on the day, adding to what has been a volatile period for the name.
The fundamental backdrop for TRGP is mixed. The company missed first-quarter earnings estimates by a meaningful margin, delivering earnings per share well below the consensus, despite year-on-year improvement in absolute terms. That earnings miss appears to have lingered in investors’ minds even as the company reinforced its dividend policy and appointed a new board member with a ConocoPhillips background — moves typically designed to project stability and governance confidence.
Midstream infrastructure players like Targa benefit from the structural growth in natural gas and natural gas liquids volumes, and several analysts continue to view the longer-term investment case positively. However, when a stock with a high valuation misses earnings expectations and then faces broad technical deterioration, short-term price pressure can persist regardless of the strategic narrative. The low bull-signal count suggests limited technical support at current levels.
4. Williams Companies (WMB) – 13 technical sell signals
Price: $70.79 | Daily change: -5.93%
View the full technical analysis of Williams Companies
Williams Companies matches Targa Resources on the bearish signal count with 13 sell signals and just 2 bull signals, and the stock fell nearly 6% on the day. The identical signal profile to TRGP is perhaps unsurprising given that both are large-cap midstream energy names exposed to broadly similar macro forces affecting natural gas infrastructure valuations.
Williams has been particularly active on the corporate development front. The company recently secured a $5.34 billion investment from a Blackstone-led consortium — alongside Apollo and KKR — in exchange for a 49% stake in five behind-the-meter power projects. That deal, along with reported advanced discussions to acquire Momentum Midstream for approximately $5.5 billion, signals aggressive growth ambitions. Large acquisition strategies, however, can introduce balance sheet and integration risk that some investors price in negatively, at least in the near term.
Despite strong longer-term total returns and continued earnings growth, the technical picture has deteriorated sharply. When a stock with elevated valuations undertakes multiple large capital deployments simultaneously, the market often reassesses the risk profile, and that reassessment appears to be playing out in the price action and our indicator readings today.
5. AvalonBay Communities (AVB) – 12 technical sell signals
Price: $187.56 | Daily change: -1.70%
View the full technical analysis of AvalonBay Communities
AvalonBay Communities rounds out our top five with 12 bearish technical signals and 7 bullish ones — making it the most balanced of the group, though the bears still hold a clear edge. The daily price decline was also the most modest on the list at -1.70%, suggesting the technical deterioration here is more gradual than the sharp single-day dislocations seen higher up the rankings.
The fundamental picture for AVB is genuinely nuanced. The residential REIT reported second-quarter core funds from operations ahead of analyst estimates, driven by same-store revenue gains, and lifted its full-year guidance as a result. A potential merger with Equity Residential — reported in late May and apparently progressing toward a close in the second half of 2026 — adds another layer of corporate complexity that the market is still working to price.
Merger arbitrage dynamics can create unusual technical patterns for acquirers, as investors weigh dilution risk, integration costs and regulatory uncertainty against the strategic logic. Mizuho raised its price target earlier in the summer, and short interest remains relatively low, which is an important consideration for anyone contemplating a short position here. The 12 bearish signals warrant monitoring, but the higher bull-signal count and the active M&A situation make this the most speculative short candidate of the five.
