Our technical scanner evaluates every stock in the S&P 500 and Nasdaq 100 each trading day, tallying bullish and bearish indicator signals across momentum, trend, volume and volatility metrics. When bearish signals significantly outweigh bullish ones, a stock surfaces as a potential short candidate. Below are the five names generating the strongest sell-side technical readings as of 7 August 2026.
Important risk warning: Short selling involves risks that go well beyond those of a conventional long position. Losses on a short trade are theoretically unlimited, margin requirements can force premature closure, and a positive news catalyst can trigger a sharp short squeeze. The analysis below is purely technical in nature and should not be treated as a recommendation to sell or short any security. Always conduct your own due diligence and consider consulting a licensed financial adviser before acting.
1. Datadog (DDOG) – 16 technical sell signals
Price: $229.29 | Daily change: -19.03%
View the full technical analysis of Datadog
Datadog tops this week’s list with a commanding 16 bearish signals against just 4 bullish ones, reflecting what appears to be severe technical damage following a brutal single-session sell-off. The stock shed nearly a fifth of its value in one day after its quarterly earnings report, despite the company delivering results that exceeded Wall Street’s expectations on both the top and bottom lines and nudging its full-year outlook higher. The market’s reaction was widely described as extreme and disproportionate, yet the price action itself is a technical reality that cannot be ignored.
The most plausible explanation circulating among analysts is that investors had already priced in an acceleration of revenue growth beyond what management guided, leaving the stock vulnerable once the numbers failed to clear that elevated bar. Some commentators have also suggested that concerns about competition from artificial intelligence platforms, including OpenAI, may be weighing on the longer-term growth narrative, adding a layer of uncertainty to forward estimates.
From a purely technical standpoint, a move of this magnitude typically leaves behind significant overhead resistance, as investors who held through the drop may look to exit on any near-term recovery. With momentum indicators likely deeply oversold yet trend signals firmly negative, the chart presents a conflicted picture that warrants close monitoring before any directional trade is considered.
2. Host Hotels & Resorts (HST) – 14 technical sell signals
Price: $23.38 | Daily change: -6.96%
View the full technical analysis of Host Hotels & Resorts
Host Hotels & Resorts, the Bethesda-based lodging REIT, registers 14 bearish technical signals and only 3 bullish ones, placing it firmly in second position on this week’s scan. The stock fell nearly 7% on the session recorded in our data, underperforming the broader market on a day when the S&P 500 itself declined only modestly. That kind of relative weakness is precisely the sort of signal that technical sell indicators are designed to flag.
The fundamental picture is not uniformly negative. The company reported second-quarter results that surpassed analyst expectations, and several analysts raised their price targets earlier in the year, citing tailwinds from the luxury hotel segment, improving revenue per available room, and anticipated demand from major international events including the FIFA World Cup. Seeking Alpha contributors have maintained a constructive fundamental view, highlighting solid operating margins and conservative balance sheet management.
Nevertheless, the technical signals suggest the stock may be losing price momentum within a broader sector rotation away from rate-sensitive real estate names. With interest rate sensitivity a known characteristic of REITs, any shift in market expectations around Federal Reserve policy could amplify downside pressure. Prospective short sellers should weigh the stock’s meaningful dividend yield, which creates a direct cost to maintaining a short position over time.
3. Rockwell Automation (ROK) – 13 technical sell signals
Price: $441.80 | Daily change: -1.83%
View the full technical analysis of Rockwell Automation
Rockwell Automation joins the list with 13 bearish signals against 4 bullish ones, and like several other names in this week’s scan, it is experiencing a so-called “sell the news” dynamic. The Milwaukee-based industrial automation specialist delivered fiscal third-quarter earnings that beat consensus estimates on both revenues and profits, yet the shares declined on the day of the announcement. This pattern of falling on good news is a classic warning sign in technical analysis, suggesting that positive expectations were already embedded in the share price before results were published.
The longer-term fundamental story remains broadly supportive. The company has delivered strong multi-year total returns, and analysts tracking the industrial automation space continue to view Rockwell favourably relative to peers such as Honeywell. A recent contract win in the food production sector also highlighted the breadth of its robotics capabilities. However, valuation concerns have surfaced, with some commentators noting that the stock may be pricing in a degree of perfection that leaves little room for disappointment.
Technically, the combination of a post-earnings gap down and accumulating sell signals across trend and momentum indicators suggests that near-term price pressure could persist. Traders considering a short position should be aware that any renewed positive catalyst in the industrial automation theme could trigger a swift reversal.
4. Viatris (VTRS) – 13 technical sell signals
Price: $16.29 | Daily change: -7.71%
View the full technical analysis of Viatris
Viatris shares a 13-signal bearish reading with Rockwell but ranks fourth owing to a slightly lower bull signal count of just 2, pointing to a near-absence of technical support. The Canonsburg-based generics and branded pharmaceuticals company dropped over 7.7% on the session captured in our data, a substantial move for a healthcare name not typically known for high daily volatility. The stock had previously delivered a remarkable multi-year rally of close to 95%, and some analysts now characterise it as fairly valued following that run-up.
The fundamental newsflow is genuinely mixed. On the positive side, the company beat second-quarter earnings estimates, secured a new FDA approval for a contraceptive patch, and progressed a portfolio divestiture by agreeing to sell the rights to eye drug Tyrvaya for up to $100 million. These are not the hallmarks of a business in distress. However, debate persists around whether the stock is meaningfully undervalued or simply reasonably priced after its sharp appreciation, and the elevated short-term price decline suggests the market may be reassessing that question.
From a technical perspective, a sharp daily decline combined with a very low bull signal count implies broad-based deterioration across multiple indicator categories. Traders should note that pharmaceutical stocks can be acutely sensitive to regulatory announcements, which can produce sudden and unpredictable price gaps in either direction.
5. Federal Realty Investment Trust (FRT) – 12 technical sell signals
Price: $117.91 | Daily change: -3.22%
View the full technical analysis of Federal Realty Investment Trust
Federal Realty Investment Trust rounds out this week’s list with 12 bearish signals against 5 bullish ones. The North Bethesda-based REIT, which focuses on high-quality mixed-use retail properties in affluent coastal markets, declined more than 3% on the session and, notably, was reported to have posted its third consecutive daily loss around that period. Persistent multi-day weakness of this kind can itself reinforce downward momentum as algorithmic and trend-following strategies pile on.
The fundamental backdrop is considerably more constructive than the technical picture implies. Federal Realty delivered second-quarter funds from operations that beat analyst expectations and subsequently raised its full-year guidance, a combination that typically attracts positive attention. Long-term income-oriented investors have highlighted the trust’s durable dividend track record and its differentiated positioning in densely populated, high-barrier-to-entry retail corridors. Several analysts have maintained positive views, arguing the trust offers a compelling blend of income and growth.
The divergence between a solid fundamental update and deteriorating technical signals may reflect broader sector-level selling pressure on REITs, possibly driven by interest rate expectations. As with Host Hotels, short sellers must factor in the cost of carrying a dividend-paying position on the short side. The 5 remaining bull signals also hint that the technical picture is not uniformly negative, warranting caution before establishing a bearish trade.
