Our technical indicator scanner runs daily across the S&P 500 and Nasdaq 100, ranking stocks by the balance of bullish versus bearish signals generated from a broad suite of momentum, trend, and volume-based indicators. Below are the five stocks that registered the strongest technical buy signals on 4 August 2026. As always, technical signals should be considered alongside your own fundamental research and risk tolerance.
1. Monolithic Power Systems (MPWR) – 7 technical buy signals
Price: Data pending | Daily change: N/A

Monolithic Power Systems leads this week’s scanner with seven bullish signals against just one bearish reading — the strongest overall score in today’s screen. The technical picture was reinforced at the end of July when MPWR crossed back above its 20-day moving average, a widely watched near-term momentum trigger that often attracts fresh buying interest from trend-following investors.
The fundamental backdrop appears supportive. The company reported a sharp jump in its share price in early August, driven by investor enthusiasm around its expanding role in AI rack-level power management. Data centre operators are under increasing pressure to solve power-density constraints, and Monolithic Power’s product lineup is increasingly cited as a critical enabler in that space, with a growing backlog pointing to continued demand.
Longer-term, the stock has delivered exceptional returns, and several institutional fund managers have highlighted it as a core holding within mid-cap growth strategies. While valuation questions have been raised in some corners of the market, the technical signals suggest that price momentum remains firmly intact for now.
2. Fortinet (FTNT) – 6 technical buy signals
Price: Data pending | Daily change: N/A
View the full technical analysis of Fortinet
Fortinet registers six bullish technical signals, placing it joint second in today’s ranking. The cybersecurity firm released its second-quarter financial results at the end of July, reporting revenue of approximately $2 billion, with improving billings and a management decision to raise full-year guidance. The market responded positively, lifting the stock meaningfully on the day following the announcement.
From a business perspective, Fortinet’s integrated security platform — anchored by its FortiGate hardware and FortiOS operating system — continues to generate cross-selling opportunities across its existing customer base. Analysts at Barclays raised their price target significantly in June, though they maintained a neutral rating, suggesting the market sees a credible growth story even if opinions differ on the degree of upside remaining.
It is worth noting that some valuation-based analysis positions the stock as trading at a premium relative to intrinsic value estimates after a multi-year run of strong gains. Investors weighing the technical signals here should keep that broader context in mind, particularly if cybersecurity sector sentiment were to shift.
3. Teradyne (TER) – 6 technical buy signals
Price: Data pending | Daily change: N/A

Teradyne also scores six bullish signals, sitting alongside Fortinet in second place. The semiconductor testing specialist delivered a notably strong second-quarter earnings report at the end of July, with both revenues and earnings per share coming in well ahead of analyst expectations. Sales roughly doubled year-on-year to reach $1.33 billion, a figure that prompted a double-digit percentage jump in the share price on the day of reporting.
The results appear to reflect a broader surge in demand for testing equipment tied to the rapid proliferation of custom silicon chips, including the application-specific processors being developed by major technology companies for AI workloads. Several institutional investment managers have recently highlighted Teradyne as a beneficiary of this structural shift in semiconductor design.
The strong earnings momentum aligns well with the bullish technical picture. After a difficult period earlier in the year — including a sharp one-day decline of over 13% in February — the stock appears to have regained solid footing. The convergence of positive fundamental news flow and improving technicals makes this one worth monitoring closely.
4. Amazon (AMZN) – 5 technical buy signals
Price: Data pending | Daily change: N/A
View the full technical analysis of Amazon
Amazon enters the top five with five bullish signals and no bearish readings — a clean technical profile that reflects the momentum generated by an exceptionally strong set of second-quarter results. The stock crossed a $3 trillion market capitalisation milestone in late July and surged further following earnings, as Amazon Web Services delivered year-on-year growth of close to 37%, its fastest rate in several years.
The earnings report also confirmed that the company’s sustained capital expenditure programme in data centres and AI infrastructure is beginning to translate into accelerating revenue growth, a development that appears to have shifted the narrative for investors who had been cautious about near-term returns on that spending. Wall Street analysts responded by raising their assessments of the stock in meaningful numbers following the results.
Amazon also completed a substantial investment commitment to OpenAI during this period, underscoring the company’s strategic positioning within the AI ecosystem. While the stock’s sharp post-earnings move means it is no longer trading at undemanding levels, the combination of clean technicals and improving fundamental momentum keeps it firmly in focus.
5. CrowdStrike (CRWD) – 5 technical buy signals
Price: Data pending | Daily change: N/A
View the full technical analysis of CrowdStrike
CrowdStrike rounds out the top five with five bullish signals and no bearish readings. The cybersecurity platform completed a four-for-one stock split in February 2026, and the adjusted share price has since attracted continued interest from both institutional and retail investors. The stock has gained approximately 70% in the year to date according to recent reports, a performance that reflects sustained confidence in its platform-led approach to enterprise security.
The company reported its most recent quarterly results in early May, beating headline estimates on revenue, earnings per share, and net new annual recurring revenue, though the share price dipped following the announcement — a pattern sometimes seen when strong results are already reflected in valuations ahead of reporting. More recent trading data from late July showed the stock experiencing some short-term softness relative to the broader market.
Despite that near-term choppiness, the technical signals as of 4 August point in a constructive direction. CrowdStrike remains one of the more closely watched names in cybersecurity, and with no bearish signals currently flagged by the scanner, the technical set-up warrants attention from investors already familiar with the company’s fundamentals.
