Our technical scanner runs daily across the full S&P 500 and Nasdaq 100 universes, weighing dozens of indicators — from moving-average crossovers and momentum oscillators to volume patterns and relative strength — to flag stocks showing the most concentrated cluster of bearish signals. Below are the five names that rose to the top of that screen on 21 July 2026. A high bear-signal count does not guarantee a price decline; it simply means the technical picture is tilted to the downside by multiple independent measures.
Important risk warning: Short selling is significantly more risky than buying equities. Losses on a short position are theoretically unlimited, borrowing costs can erode returns, and a short squeeze can cause rapid, severe losses. The stocks below are identified purely on technical grounds and should be approached with robust risk-management rules, including strict stop-loss discipline. Always conduct your own due diligence before acting on any of the information presented here.
1. Warner Bros. Discovery (WBD) – 13 technical sell signals
Price: $25.86 | Daily change: -3.76%
View the full technical analysis of Warner Bros. Discovery
Warner Bros. Discovery leads today’s screen with the highest bear-signal count of 13, against only 9 bullish readings — a notably lopsided picture. The stock shed nearly 4% in a single session, continuing a pattern of underperformance relative to the broader market that has been flagged repeatedly over recent weeks. With 13 bearish technical triggers active simultaneously, momentum, trend and volume indicators are all pointing in the same direction.
The fundamental backdrop adds texture to the technical weakness. The proposed Paramount Skydance acquisition of WBD was dealt a significant legal blow in early July when a California judge issued a temporary restraining order, introducing material deal uncertainty and removing a potential catalyst that some investors had been pricing in. The overhang from that litigation appears to be weighing on sentiment.
Perhaps most striking, CEO David Zaslav sold approximately $59 million worth of WBD shares in mid-July. Insider selling at this scale, while not always a directional signal in isolation, tends to amplify bearish sentiment when it coincides with deteriorating price action and unresolved corporate uncertainty. Bears will watch closely for any further legal developments around the deal.
2. IDEX Corporation (IEX) – 12 technical sell signals
Price: $221.24 | Daily change: -1.64%
View the full technical analysis of IDEX Corporation
IDEX Corporation registers 12 bearish technical signals against just 4 bullish ones, placing it firmly in second position. The industrial-fluid-handling specialist has been tracking closely with the broader market over the past six months, but that correlation means it has also absorbed the market’s recent softness without any meaningful outperformance to cushion the blow. The bear-to-bull ratio of 3-to-1 suggests the technical deterioration is broad-based rather than concentrated in a single indicator.
From an earnings perspective, IDEX’s most recent results showed modest organic revenue growth of around 1% in Q4 2025, with order growth in its Health and Science Technologies segment helping to offset softer readings elsewhere. The company’s 2026 guidance, while not alarming, did not provide the upside surprise needed to reinvigorate the chart. Adjusted EBITDA margins edged up by a small amount year-on-year, but incremental margin improvement alone has not been sufficient to attract sustained buying interest.
A recent third-party analysis highlighted IEX as carrying elevated risk relative to peers, and the stock has underperformed on several individual trading sessions when sector peers managed gains. For technically oriented investors, the confluence of 12 bearish indicators alongside uninspiring fundamental momentum makes this an interesting name to monitor on the short side, though industrial stocks can be sensitive to macro surprises.
3. Boeing (BA) – 11 technical sell signals
Price: $209.48 | Daily change: -2.13%
View the full technical analysis of Boeing
Boeing appears on this screen with 11 bearish signals and only 4 bullish ones — a ratio that reflects persistent technical deterioration in a stock that has struggled to build any durable upward momentum. Tuesday’s decline of more than 2% follows a pattern of underperforming the general market on down days, which is a characteristic that trend-following indicators tend to capture quickly and penalise heavily.
The most significant recent development is the fresh delay to 777X certification, which analysts suggest could now extend into the late 2020s. Combined with ongoing supply-chain disruptions, this pushes back one of Boeing’s most important near-term revenue contributors and introduces further uncertainty around the production ramp. The stock had enjoyed brief rallies in June — on news of a fourth 737 MAX assembly line and a diplomatic development affecting the Strait of Hormuz — but neither catalyst managed to change the underlying technical trend.
On a more constructive note, Boeing did win a legal appeal in July that decertified a major shareholder class action related to 737 MAX safety claims, and it secured a substantial satellite contract from the Department of Defense. However, positive headline events have repeatedly failed to sustain upward price momentum, which itself is a bearish technical signal that reinforces the scanner’s reading.
4. Builders FirstSource (BLDR) – 11 technical sell signals
Price: $72.70 | Daily change: -2.10%
View the full technical analysis of Builders FirstSource
Builders FirstSource ties Boeing on 11 bearish signals, but its bull count is even thinner at just 3, giving it the weakest bull-to-bear ratio among the tied names. The building-materials distributor has been under pressure as housing market dynamics remain challenging, with elevated mortgage rates continuing to suppress new-construction activity and, by extension, demand for the products BLDR supplies to homebuilders.
A notable development in late June was the company’s addition to the Russell 2500 Index. Index inclusion often triggers mechanical buying from passive funds, yet the stock’s chart has continued to weaken, suggesting that any index-driven demand is being absorbed — and then some — by selling pressure from other market participants. When positive structural events fail to lift price action, it reinforces the technical picture the scanner is identifying.
While BLDR did outperform in its Q1 2026 earnings relative to sector peers, the broader outlook for home construction materials remains subdued. Analysts and commentators have debated whether BLDR represents an undervalued play on an eventual housing rebound, but technical indicators suggest the market has not yet begun pricing in that recovery. Investors considering a short position should be aware that any positive shift in housing data or rate expectations could prompt a sharp reversal.
5. BXP, Inc. (BXP) – 11 technical sell signals
Price: $67.90 | Daily change: -2.79%
View the full technical analysis of BXP, Inc.
BXP, Inc. — one of the largest office-focused real estate investment trusts in the United States — rounds out the list with 11 bearish signals and only 4 bullish ones. The office REIT sector has faced structural headwinds since the widespread adoption of hybrid working, and BXP has not been immune. The stock fell almost 3% in today’s session, and the technical picture reflects accumulated damage to trend, momentum and relative-strength indicators.
The news flow around BXP has been notably mixed. Scotiabank initially cut its price target on the stock earlier in the year, then reversed course in June with an upgrade to Outperform, citing interest-rate sensitivity as a potential tailwind. Yet even that analyst endorsement has not been enough to arrest the technical deterioration — a divergence that experienced technicians often interpret as a sign that the underlying trend has further to run before a genuine inflection takes hold.
Television personality Jim Cramer’s publicly stated aversion to office REITs in general, and BXP in particular, reflects a broader market skepticism about the sector’s long-term demand outlook. While interest-rate cuts could provide a meaningful relief rally for rate-sensitive names like BXP, the current technical configuration suggests that any such catalyst has not yet materialised in price. Short sellers should factor in the stock’s dividend yield, which adds a carry cost to any short position held over distribution dates.
