Each trading day, our technical analysis scanner evaluates every stock in the S&P 500 and Nasdaq 100, scoring each name against a comprehensive set of momentum, trend and oscillator indicators. Today, 2 September 2026, we highlight the five names generating the highest number of bearish technical signals — potential short candidates for members who employ that strategy. A high bear-signal count does not guarantee a decline; it simply indicates that multiple independent technical measures are currently aligned on the downside.
Important risk warning: Short selling involves risks that go well beyond those of a standard long position. Losses are theoretically unlimited, borrowing costs can be significant, and a stock can be subject to a short squeeze at any time. Please ensure you fully understand these risks and consider your own financial situation before initiating any short position.
1. Union Pacific Corporation (UNP) – 15 technical sell signals
Price: $290.62 | Daily change: -3.34%
View the full technical analysis of Union Pacific Corporation
Union Pacific tops today’s bear-signal table with 15 bearish technical readings against just 5 bullish ones — the most lopsided ratio on our scanner. The stock’s 3.34% single-session drop to $290.62 is notable given that the shares were trading close to $310 as recently as late August, suggesting that near-term selling pressure has accelerated sharply in a matter of days.
From a fundamental news perspective, the picture looks considerably brighter, which is precisely what makes UNP an interesting case study in the divergence between price action and corporate developments. The railroad reported solid second-quarter 2026 results, recently raised its dividend to $1.42 per share per quarter, and hedge-fund positioning reportedly favoured UNP over peers such as Canadian Pacific. The stock had also gained roughly 26% year-to-date at its peak, suggesting it may simply have run ahead of itself.
For technically oriented bears, the abrupt reversal from the $310 area could indicate that the strong 2026 rally is losing momentum. However, members should weigh the robust fundamental backdrop — steady freight volumes, a growing dividend and institutional support — carefully before treating this purely as a short opportunity. The bull-signal count of 5 confirms that not all technical evidence points in the same direction.
2. Ameriprise Financial (AMP) – 14 technical sell signals
Price: $542.64 | Daily change: -1.89%
View the full technical analysis of Ameriprise Financial
Ameriprise Financial scores 14 bearish technical signals and only 4 bullish ones, giving it the second-weakest technical profile on today’s scan. The shares fell 1.89% to $542.64, even as recent commentary noted the stock was trading near record levels with analysts maintaining a broadly positive stance. That tension between proximity to all-time highs and a deteriorating technical picture is worth watching closely.
On the news side, Ameriprise has been an active capital allocator in 2026, completing a share repurchase programme that reduced the float by approximately 8%. Buybacks of that scale can provide a degree of price support, and analysts continue to assign a consensus Moderate Buy rating. Earnings revisions tracked by research services have remained constructive, and the wealth-management business appears to be benefiting from elevated equity markets.
Nevertheless, stocks that have run hard and are sitting near multi-year peaks can be vulnerable to rotation and profit-taking. From a technical standpoint, the 14-to-4 bear-to-bull imbalance suggests momentum may be fading. Short sellers should bear in mind, however, that an active buyback programme and positive analyst sentiment represent meaningful headwinds for any bear thesis. Position sizing and stop-loss discipline are especially important in such situations.
3. Cadence Design Systems (CDNS) – 14 technical sell signals
Price: $313.04 | Daily change: -7.60%
View the full technical analysis of Cadence Design Systems
Cadence Design Systems posts a striking 7.60% single-session decline to $313.04, by far the largest one-day loss among today’s five candidates. The electronic design automation software company shares 14 bearish signals with Ameriprise, but the severity of the intraday move distinguishes it. The broader market was softer on the session in question, with the S&P 500 off around 0.71%, meaning CDNS substantially underperformed the index.
The fundamental backdrop has been more complicated. Cadence reported strong second-quarter 2026 results and raised its full-year guidance, citing accelerating demand tied to artificial intelligence design workflows. The stock reportedly surged more than 10% following those results and was trading above $340 in late August. This makes the subsequent reversal back toward $313 — and below — all the more striking, and may reflect profit-taking after an extended rally rather than any deterioration in the business itself.
Some analysts have highlighted valuation concerns even as they acknowledge the strength of the AI-driven demand narrative. A Seeking Alpha piece from late August framed the pullback as a potential buying opportunity, which illustrates how divided opinion can be at these levels. Bears considering CDNS should recognise that the underlying AI tailwind is credible and that institutional buyers have reportedly been active on dips, making a sustained short position challenging to hold.
4. Shopify Inc. (SHOP) – 14 technical sell signals
Price: $139.82 | Daily change: -5.12%
View the full technical analysis of Shopify Inc.
Shopify rounds out the trio of stocks tied at 14 bearish technical signals, but its 5.12% decline and 7-signal bull count give it a slightly more mixed profile than either AMP or CDNS. Nevertheless, the bear-to-bull ratio of 2-to-1 still flags meaningful downside technical pressure. The Nasdaq 100-listed e-commerce infrastructure company has had a volatile year and the drop to $139.82 may be testing key chart support levels.
On the corporate news front, Shopify’s board authorised a substantial addition to its share repurchase programme earlier in 2026, taking total buyback capacity to $5 billion. Share repurchase programmes of this magnitude can act as a floor under the stock price, as the company steps in as a buyer during periods of weakness. That is an important consideration for anyone evaluating a short position — ongoing buybacks create a persistent source of demand that can frustrate bears.
Shopify has faced questions about valuation relative to its growth rate, and some investors have debated whether the stock represents fair value at current levels. However, the expanded buyback and the company’s continued investment in merchant services and AI-driven commerce tools suggest management retains confidence in the long-term trajectory. As with all short candidates on this list, the elevated risk of a short squeeze — particularly in a highly watched, widely held tech name — should be taken seriously.
5. BlackRock (BLK) – 13 technical sell signals
Price: $1,128.10 | Daily change: -2.38%
View the full technical analysis of BlackRock
BlackRock closes out today’s list with 13 bearish signals against 5 bullish ones. The world’s largest asset manager fell 2.38% to $1,128.10, extending what appears to have been a period of choppy trading through late August. Earlier in that period the stock had dipped 1.65% in a single session, suggesting that selling pressure has been building gradually rather than arriving in one sharp move.
The news flow around BlackRock has been broadly constructive in 2026. The firm reportedly beat second-quarter earnings estimates, prompting analyst upgrades and an upward revision to modelled fair value estimates. BlackRock also named a new head of its global product unit, signalling continued organisational investment. Meanwhile, the company is exploring options for a sizeable private credit loan portfolio inherited via its TCP Capital operations, a process that could crystallise value but also introduces some uncertainty.
BlackRock’s structural advantages — dominant ETF market share through iShares, growing private markets capabilities and a recurring fee-based revenue model — represent solid fundamental support. With interest rate expectations continuing to shift, asset flows into fixed-income ETFs in particular could prove a meaningful tailwind. The technical weakness may therefore reflect broader market nervousness rather than stock-specific deterioration. Bears should weigh these durable competitive strengths carefully against the technical signals before acting.
