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. The table below presents the five names that generated the strongest net bullish readings on 21 August 2026. As always, technical signals are one input among many and should be considered alongside your own fundamental research and risk tolerance.
1. Coinbase Global (COIN) – 14 technical buy signals
Price: $172.35 | Daily change: +7.58%
View the full technical analysis of Coinbase Global
Coinbase was the standout mover on the day, gaining well over 7% and topping our scanner with 14 bullish signals against just 5 bearish ones. The price surge appears to reflect two converging forces: a broad rally in cryptocurrency spot markets, with Bitcoin crossing the $70,000 level and triggering significant short covering that flows directly into exchange volumes, and renewed optimism around US regulatory clarity for digital assets following political support for the so-called CLARITY Act.
On the business side, Coinbase’s derivatives subsidiary Deribit is preparing to launch perpetual contracts tied to individual equities at the end of August, a move that broadens the company’s revenue streams beyond spot crypto trading. The derivatives expansion has drawn fresh attention from investors looking for growth optionality within the crypto ecosystem.
It is worth noting that as recently as early August, COIN was trading near $148 and had attracted commentary suggesting the stock looked expensive relative to its fundamentals. The sharp recovery since then underscores the volatility inherent in crypto-linked equities, and investors should weigh that risk carefully alongside the strong technical picture.
2. Jack Henry & Associates (JKHY) – 14 technical buy signals
Price: $165.08 | Daily change: +1.24%
View the full technical analysis of Jack Henry & Associates
Jack Henry & Associates matched Coinbase on bullish signals but with a notably cleaner bear-signal count of just 4, reflecting a more measured and sustained technical recovery. The fintech provider, which delivers core processing and payments technology to community and mid-tier banks, reported record fourth-quarter and full fiscal-year 2026 results earlier in the week, beating consensus estimates on both revenue and earnings per share.
Following those results, several analysts raised their price forecasts for the stock, citing expanding operating margins and accelerating revenue growth as evidence that the company’s long-term investment cycle is beginning to pay off. One independent valuation framework placed the stock at a meaningful discount to its assessed intrinsic value, adding a fundamental dimension to the technical momentum.
The company also recently added a document delivery and print-mail integration partner to its fintech ecosystem, a relatively modest but consistent sign of the incremental product expansion strategy that has characterised Jack Henry’s approach. For investors seeking exposure to financial technology with a lower-volatility profile than pure-play fintechs, JKHY’s combination of steady fundamentals and strong technical signals makes it worth closer examination.
3. Progressive Corporation (PGR) – 14 technical buy signals
Price: $220.34 | Daily change: +1.41%
View the full technical analysis of Progressive Corporation
Progressive Corporation, the US auto and property insurer, rounds out a trio of stocks tied at 14 bullish signals. With 6 bearish signals, it carries a slightly wider spread than Jack Henry, but its technical posture remains firmly constructive. The stock has attracted persistent institutional interest over the past year, with Bank of America and Goldman Sachs among the major brokerages that have highlighted the company in positive terms at various points in 2026.
Progressive’s operational model continues to draw attention for its disciplined underwriting approach and ability to grow market share while maintaining profitability metrics that peers have struggled to replicate. The insurer has been consistently cited in discussions around financially resilient, lower-risk equity holdings, a characterisation that appears well-supported by the company’s track record of navigating challenging loss environments.
It is worth noting that Bank of America did lower its price target for Progressive earlier in the year, reflecting some moderation in near-term expectations. The current technical strength suggests the market may be looking through that caution, though investors will want to monitor upcoming premium growth and combined ratio data before drawing firm conclusions.
4. CF Industries Holdings (CF) – 13 technical buy signals
Price: $125.70 | Daily change: +5.61%
View the full technical analysis of CF Industries Holdings
CF Industries, one of the largest nitrogen fertiliser producers in North America, delivered the second-strongest single-day price gain on our list, rising more than 5.6% to close at $125.70. The stock scored 13 bullish signals against only 3 bearish ones, giving it the cleanest bull-to-bear ratio of any name in today’s top five. That combination of strong momentum and limited technical headwinds is noteworthy.
The agricultural chemicals sector has been responding to shifts in global supply dynamics, energy input costs, and crop commodity prices, all of which influence nitrogen fertiliser demand and pricing. CF Industries, with its large and relatively low-cost production base, is generally well positioned to benefit when those dynamics are favourable, though the sector is also subject to meaningful cyclicality.
One independent valuation analysis published on the day suggested the stock may be trading at a modest premium to its assessed fair value following the recent move, a reminder that strong technical signals do not always coincide with fundamental cheapness. Investors considering CF Industries should pay close attention to natural gas prices, which represent the primary input cost for ammonia and urea production, as well as near-term agricultural demand trends.
5. S&P Global (SPGI) – 13 technical buy signals
Price: $432.16 | Daily change: +1.29%
View the full technical analysis of S&P Global
S&P Global closes out today’s list with 13 bullish signals and, strikingly, just a single bearish signal – the most lopsided ratio of the five stocks covered here. The financial data and analytics giant, whose businesses span credit ratings, market intelligence, commodity insights, and index management, has experienced a meaningful pullback from prior highs during 2026, which some market observers have characterised as an opportunity rather than a structural deterioration in the business.
Prominent investment manager Pershing Square has publicly detailed its investment case for S&P Global, pointing to the company’s dominant position in benchmark indices and arguing that concerns about artificial intelligence disintermediating its core data businesses are overstated. The corporate structure is also in flux: S&P Global has announced plans to spin off its Mobility division as a separately listed entity, a move that could sharpen the investment profile of the remaining business.
Leadership and operational changes earlier in the year attracted some uncertainty, but the technical picture suggests that investors are increasingly comfortable with the company’s strategic direction. With recent quarterly earnings having beaten analyst expectations, the combination of improving sentiment, a cleaner technical signal set, and potential spin-off optionality makes SPGI a stock to watch closely in the weeks ahead.
