Our technical scanner combs through hundreds of S&P 500 and Nasdaq 100 constituents each trading day, ranking stocks by the balance of bullish versus bearish signals across a broad set of indicators. On 25 August 2026, five names stood out with particularly strong technical setups. Here is a closer look at each of them.
1. Costco (COST) – 18 technical buy signals
Price: $971.40 | Daily change: +2.5%
View the full technical analysis of Costco
Costco tops today’s scanner with a perfect 18 bullish signals and zero bearish ones — the strongest reading across the entire index universe on this date. The stock is trading near $971, recovering sharply after a brief mid-week dip that briefly pushed shares back toward the $933 level. The technical picture suggests broad-based momentum across multiple timeframes and indicator families.
On the fundamental side, Costco continues to post robust monthly sales figures, and recent commentary highlights that elevated fuel prices are drawing shoppers to its competitively priced petrol stations, reinforcing overall warehouse traffic. Membership retention remains one of the strongest in retail, and the company has continued its measured warehouse expansion programme.
That said, analysts have flagged the stock’s valuation — it trades at over 40 times forward earnings — as a potential constraint on further re-rating. Several observers have noted that much of the good news may already be reflected in the share price. Investors should weigh the exceptionally clean technical setup against a valuation that leaves limited room for error on the fundamental side.
2. Arch Capital Group (ACGL) – 14 technical buy signals
Price: $101.14 | Daily change: +1.76%
View the full technical analysis of Arch Capital Group
Arch Capital Group takes second place with 14 bullish signals against 4 bearish ones. The Bermuda-based specialty insurer and reinsurer has been on a remarkable long-term run, with the stock having delivered a cumulative gain of well over 175% during the past several years. Breaking through the $100 mark represents a meaningful psychological level, and the technical signals suggest the move is being confirmed across a range of indicators.
The company’s second-quarter 2026 results were well received, with after-tax operating income coming in solidly and the company continuing to buy back its own shares. Revenue for the period came in near $4.7 billion, with net income exceeding $1 billion. Management navigated a quarter that included some catastrophe-related costs without any material deterioration in underlying margins.
One item worth monitoring is insider activity: the company’s CFO recently exercised stock options and sold just over 11,000 shares in August. Option-related sales are not unusual and do not necessarily signal a change in outlook, but investors may wish to factor this into their broader assessment alongside the otherwise constructive technical and fundamental backdrop.
3. Moody’s Corporation (MCO) – 13 technical buy signals
Price: $511.35 | Daily change: +1.6%
View the full technical analysis of Moody’s Corporation
Moody’s Corporation earns third place with 13 bullish and just 1 bearish signal. The ratings and analytics giant has been demonstrating strong fundamental momentum in 2026, with second-quarter results showing revenue growth of 15% year-on-year and adjusted earnings per share growing at an even faster pace. Both its Moody’s Investors Service (MIS) and Moody’s Analytics (MA) divisions contributed to the broad-based strength.
From a longer-term perspective, Moody’s remains one of the positions that Warren Buffett’s Berkshire Hathaway has held continuously since 2010, a fact that continues to attract attention from value-oriented investors. The stock is currently trading well below its 52-week high, which some analysts interpret as a potential re-entry opportunity, while others have maintained a more cautious stance following a period of strong appreciation.
The single bearish signal in today’s reading is a minor caveat in an otherwise technically constructive picture. Valuation remains a topic of debate among analysts: after a significant rally earlier in the year, some observers have moved to a neutral stance on stretched multiples, even while acknowledging that the underlying business continues to perform at a high level.
4. Arthur J. Gallagher & Co. (AJG) – 12 technical buy signals
Price: $271.99 | Daily change: +3.1%
View the full technical analysis of Arthur J. Gallagher & Co.
Insurance brokerage firm Arthur J. Gallagher posts a strong session, gaining over 3% to bring its technical reading to 12 bullish signals against 5 bearish ones. The stock has been one of the steadier performers in the financial services space, benefiting from durable organic revenue growth, disciplined margin management, and an active acquisition strategy that has broadened its geographic and product footprint.
A notable development in 2026 has been the ongoing integration of AssuredPartners, a large independent insurance brokerage acquired earlier in the year. Early signs suggest the integration is proceeding constructively, and analysts following the company have highlighted that this deal materially expands Gallagher’s scale in the middle-market segment. The company has a credible track record of absorbing bolt-on and larger acquisitions without disrupting organic momentum.
First- and second-quarter results were broadly in line with expectations, with brokerage revenues continuing to grow at a healthy clip. The stock has climbed meaningfully year-to-date, and some commentators have flagged that fundamentals remain the primary driver of investor interest rather than speculative positioning. The five bearish signals in today’s reading are worth watching, but they do not override the overall bullish tilt at this stage.
5. BXP, Inc. (BXP) – 12 technical buy signals
Price: $69.99 | Daily change: +3.43%
View the full technical analysis of BXP, Inc.
BXP, Inc., formerly Boston Properties, rounds out today’s top five with 12 bullish signals and 5 bearish ones. The office-focused REIT has had a turbulent few years as the sector navigated post-pandemic demand shifts, but the technical picture on 25 August points to renewed momentum. The stock is approaching the $70 level that Scotiabank used as its upgraded price target when it moved the name to Outperform in June, making today’s close particularly noteworthy.
Operationally, BXP has been making progress. Leasing activity has improved across its premier urban office portfolio, occupancy metrics are trending in the right direction, and management raised its full-year 2026 funds from operations (FFO) guidance to a range of $6.99 to $7.05 per share. The company’s focus on high-quality, well-located assets in major gateway markets appears to be helping it outperform more commodity-oriented office peers.
Nevertheless, risks remain meaningful. Analysts have pointed to uneven rental rate trends, ongoing development costs, and refinancing obligations as factors that could limit the pace of any re-rating. Investors in this name should be comfortable with the specific dynamics of the office real estate sector and monitor macroeconomic conditions — particularly interest rate movements — closely, given the REIT structure’s sensitivity to the rate environment.
