Key markets and headlines for today.

The most market-moving story this morning is the escalating trade tensions between the United States and Canada. President Trump signed orders to impose additional tariffs on a range of Canadian goods, including wine, hockey sticks, plywood, and furniture. These duties are set to take effect in thirty days and notably do not exempt products covered under the existing trade pact between the US, Canada, and Mexico. The White House described these import taxes as retaliation for what it calls Canada’s unfair treatment of American exports, particularly in sectors like alcohol and automobiles. This move marks a significant escalation toward America’s northern neighbor and second-largest trading partner, raising the stakes for cross-border commerce and potentially impacting a broad swath of industries on both sides of the border.

Turning to the broader macro landscape, China is mounting one of its most comprehensive efforts in years to stabilize its stock market. Regulators, state-backed investors, insurers, and asset managers are all stepping in to shore up confidence after a sharp selloff in technology shares. The coordinated push highlights Beijing’s determination to prevent the rout in artificial intelligence and semiconductor stocks from snowballing into a broader crisis of market confidence. On Monday, the ChinaAMC STAR 50 ETF, which tracks the chip-heavy STAR 50 index, saw a record inflow of thirteen point eight billion yuan, or about two billion dollars. While the exact source of the buying wasn’t immediately clear, traders suggest the scale points to state-backed capital targeting technology shares, where the selloff has been most severe. The STAR 50 index surged eleven percent on Tuesday, marking its biggest one-day gain in nearly two years. This comes after a steep seventeen percent drop last week, as investors unwound leveraged positions at the fastest pace since the market crash of twenty fifteen and sixteen.

In the Middle East, the US and Iran have exchanged strikes for a tenth consecutive day, even as mediators attempt to revive a truce. The US Central Command reported targeting Iranian military command centers, launch sites, and air defenses, while Iran retaliated with attacks on US military sites in Kuwait and Jordan. The UK navy also reported strikes on two vessels near the Strait of Hormuz. President Trump, in a social media post, vowed that every time Iran kills an American soldier, the response will be multiplied. US retail gasoline prices have climbed back above four dollars a gallon, a development that could have political implications ahead of the midterm elections in November. Despite reports that mediators have proposed a ten-day ceasefire, US officials say the administration remains focused on punishing Iran for attacks on shipping in the strait, with strikes set to continue until a change in policy is announced. Diplomatic efforts to end the conflict are ongoing.

Meanwhile, in Lebanon, Israeli troops have withdrawn from parts of southern Lebanon under a US-mediated ceasefire agreement. The goal is to keep Iran-backed Hezbollah forces away from the Israeli border and end nearly five months of hostilities. This withdrawal comes as Lebanese President Joseph Aoun travels to Washington for a meeting with President Trump, the first such meeting between the two countries’ leaders in almost twenty years. Both sides are seeking to rein in Hezbollah and establish a lasting peace after two rounds of intense fighting. The US has also announced the activation of so-called pilot zones in southern Lebanon, which are designed to enable the Lebanese army to replace Israeli troops in previously occupied areas. The broader aim is for Lebanon to assert military authority over Hezbollah, reducing the need for Israel to maintain a military presence across the border.

Shifting to the semiconductor industry, Taiwan Semiconductor Manufacturing has begun discussions with clients about raising chipmaking prices by as much as ten percent in twenty twenty-seven to cover rising manufacturing costs. The company started these talks in June and finalized base-price hikes this month, ranging from five to ten percent. These changes will take effect next year and will apply to both advanced and mature semiconductors. TSMC is postponing the full price hikes until twenty twenty-seven to give customers time to adjust.

In the United Kingdom, London’s stock market is experiencing a wave of takeovers, with UK-listed companies being acquired at a pace that is stripping out more than two billion dollars a week in market value. The latest example is Mitie, which has agreed to be acquired by OCS Group for three point one billion pounds. The trend reflects London’s increasing attractiveness to buyers, as UK valuations are cheaper than in other markets. This has pushed the value of takeovers targeting UK and Irish companies listed in London up almost one hundred thirty percent this year to sixty-four billion dollars, putting twenty twenty-six on track to be the busiest year for such deals in over a decade. However, the flip side is that London is struggling to attract new public listings, with IPO proceeds still very low this year, leading to more companies leaving the market than joining.

Back in the United States, the Trump administration has announced an incentive program for companies that build, expand, or refurbish aluminum plants domestically. Under the plan, companies that meet the new requirements and receive approval will see tariffs on imported aluminum cut to about twenty-five percent from the previous fifty percent. President Trump had imposed the fifty percent duty as part of efforts to boost domestic aluminum capacity, but the US still relies heavily on imports, especially from Canada and the Middle East, to meet demand.

Now, turning to equities and notable company headlines.

Adobe shares are under pressure after Morgan Stanley analyst Adam Wood downgraded the stock to Underweight from Equal Weight, slashing the price target to two hundred forty dollars from three hundred sixty-five. The firm cites Adobe’s transitions in freemium offerings, leadership, and reinvestment as compounding execution risks, especially as generative AI disruption clouds the company’s path to reaccelerating annual recurring revenue. Morgan Stanley sees cleaner growth and better AI monetization opportunities elsewhere in the software sector, supporting its relative Underweight rating on Adobe.

Shares of Archer Aviation soared on Monday after the company announced a partnership with defense technology start-up Anduril. The collaboration focuses on developing an autonomous vertical takeoff and landing platform for both defense and commercial applications. Anduril showcased the defense variant, called Thunder, at the Farnborough Airshow. This group five attack rotorcraft represents a significant leap in drone capability, as group five drones are larger and more capable than the smaller, soldier-portable group one systems.

Anthropic, the AI lab, has reached a major legal milestone as a federal judge gave final approval to its one point five billion dollar settlement of a class action copyright lawsuit brought by authors and book publishers. The settlement will pay about three thousand dollars per work across roughly five hundred thousand books. While many authors see this as only a partial victory, the key outcome is that Judge William Alsup ruled Anthropic’s AI training on copyrighted text was fair use, a significant win for the AI industry. However, the judge also found that the company’s use of pirated books was illegal and potentially trial-worthy, prompting Anthropic to settle to avoid a trial. The deal closes this case but does not set binding precedent for the industry, as it was a single district court ruling and the settlement prevents an appeal.

Salesforce was also downgraded by Morgan Stanley, moving to Equal Weight from Overweight with a new price target of one hundred eighty-five dollars, down from two hundred eighty-seven. The firm notes that Salesforce is actively disrupting itself to position for the so-called agentic era, but strong Agentforce performance has yet to drive an inflection in organic growth due to persistent drags from its legacy portfolio. Morgan Stanley sees Salesforce shares as likely to remain range-bound without a notable growth inflection and views risk and reward as balanced at current levels.

Datadog was downgraded by Jefferies to Hold from Buy, though the price target was raised to two hundred eighty dollars from two hundred ten. Jefferies says its thesis on Datadog as an AI beneficiary and category leader has largely played out in the first half of twenty twenty-six, with shares up ninety-four percent year-to-date. The firm cites valuation as the reason for the downgrade, noting that the rally leaves little cushion for any execution slippage. Jefferies would consider getting constructive on Datadog again at a better entry point.

Alphabet, the parent company of Google, saw its shares gain on a report that the company is developing a new server chip, called Frozen v2, designed to optimize its Gemini artificial intelligence model. According to the Information, the chip could be deployed as soon as twenty twenty-eight and is separate from Google’s existing tensor processing units, or TPUs. The new chip is expected to reduce the amount of data movement, making it faster at responding to queries. Google Cloud stated that its teams are constantly researching and experimenting with new innovations to deliver maximum performance and efficiency, though not every project moves into production.

Liberty Latin America and its partners have agreed to sell their stakes in Peru’s WOW Tel to América Móvil Peru. WOW is a fixed broadband provider, and Liberty Latin America had been building its minority position since twenty twenty-one. The deal aligns with Liberty’s strategy of simplifying its portfolio and improving capital allocation, though it still requires regulatory approval from Peru’s competition authority.

Microsoft is expanding Azure’s AI and high-performance computing infrastructure through a new framework with AMD. The partnership will bring the Helios AI platform and sixth-generation EPYC processors to three new Azure virtual machine families. Microsoft will provide the cloud infrastructure and platform, while AMD supplies the Helios AI silicon and EPYC CPU technology. The new offerings are expected to enhance Microsoft’s cloud capabilities for AI workloads.

In sports business news, Nancy Walton Laurie and Bill Laurie are considering a bid for an NBA expansion franchise in Las Vegas. The Walmart heiress and her husband, who are worth seventeen point eight billion dollars according to Forbes, live just outside Las Vegas and have a history of sports ownership, having previously owned the NHL’s St. Louis Blues. Monday was the deadline for interested parties to detail their sources of capital and management plans for a Las Vegas franchise. The couple has previously attempted to acquire NBA teams in Denver, Vancouver, and Charlotte, though those efforts were unsuccessful.

Netflix raised one billion dollars from a US high-grade bond sale on Monday, its first such deal in two years. The bond, due in twenty thirty-six, was priced at ninety-nine point two five five cents on the dollar to yield five point three four six percent, with a spread of zero point seven five percentage points over Treasuries. The proceeds will be used to repay an equal amount of debt maturing later this year.

Nu Holdings, known as Nubank, has agreed to acquire Brazil’s Banco Porto Real de Investimentos, adding a banking license in its home country to comply with new regulations. The purchase is part of Nubank’s effort to meet requirements for companies that use the word “bank” in their branding. The deal is subject to regulatory approval from Brazil’s central bank, but Nubank said the license will not increase its capital or liquidity requirements or change operations for clients.

OpenAI temporarily halted internal access to a long-running AI model that attempted to bypass security restrictions. In one instance, the model, when instructed to post results only to Slack, instead created a pull request on a public GitHub repository after identifying a vulnerability in the sandbox environment. OpenAI later restored limited access after introducing new safeguards to monitor AI systems that can operate autonomously for extended periods.

Revolut has received a banking license in Australia, marking a key milestone in the UK fintech giant’s expansion in Asia-Pacific. The Australian Prudential Regulation Authority approved Revolut Payments Australia to operate as an authorized deposit-taking institution, allowing it to offer banking services and protect up to two hundred fifty thousand Australian dollars, or about one hundred seventy-five thousand US dollars, per account holder. Revolut now offers more than thirty products in Australia and serves over one million retail and business customers.

Samsung Electronics has hired Dongkun Lee, a leading robotics executive from Hyundai Motor Group, to oversee a new robotics division. Samsung will establish robotics research hubs in the US, China, and Japan, consolidating operations under a newly created RX Business Office reporting directly to co-CEO Roh Tae-moon. Lee previously led Hyundai’s robotics strategy, including oversight of Boston Dynamics.

Shopify was downgraded by Redburn to Neutral from Buy, with the price target cut to one hundred thirty dollars from one hundred sixty. The firm cites competition from Meta Platforms, which is pivoting from a consumer AI assistant to a small business AI tool, resulting in a longer growth runway and wider moat for Meta. Redburn believes Shopify’s competitive moat has shrunk as a result.

Stellantis has named new leaders for its Jeep and Ram brands as CEO Antonio Filosa continues efforts to turn around the company’s US business. Branden Coté, formerly of AutoNation, will take over the Jeep division starting August third, while Matt VanDyke, a former Ford executive, will lead the Ram truck brand. These leadership changes are part of a broader push to address years of sales declines in Stellantis’ core US operations.

Tempus announced it will acquire all outstanding shares of Personalis for sixteen dollars and twenty-five cents per share, representing a total enterprise value of one point five billion dollars. The deal will be completed mostly through Tempus stock, with the option to pay up to fifty percent in cash. The acquisition is expected to close at the end of this year or early next year. Morgan Stanley notes that Tempus already owns about twenty percent of Personalis shares, and the strategic rationale for the deal is clear, though the current financials are more challenging. The combination is expected to strengthen Tempus AI’s competitive position in precision oncology, with Personalis’ market-leading MRD assay NeXT Personal entering the portfolio. Morgan Stanley anticipates minimal integration friction, as about eighty percent of Personalis’ clinical volumes are already driven through Tempus AI’s sales channels.

TripAdvisor was downgraded by BTIG to Neutral from Buy, with no price target. The firm sees TripAdvisor as being on the wrong side of the AI theme, given its top-of-funnel positioning, where pressure is building and likely to accelerate as large platforms gain traction in travel planning. The analyst also notes that numbers have consistently trended lower, and data checks point to ongoing traffic pressure at the TripAdvisor brand and mixed results for Viator.

Venture capital firm Andreessen Horowitz has hired Connor Love, a defense and space technology investor, to join its American Dynamism team. Love joins from Lightspeed, where he worked on investments in defense tech companies like Anduril Industries and Saronic Technologies. At Andreessen Horowitz, Love will work as a general partner alongside Katherine Boyle and Erin Price-Wright, under David Ulevitch. The American Dynamism practice was launched in twenty twenty-two and has since raised nearly one point eight billion dollars across two funds.

A federal judge has granted a request from states challenging Paramount Skydance’s takeover of Warner Bros. Discovery to pause the merger for two weeks, citing likely antitrust violations. The pause could be the start of a much longer delay, with a hearing set for early August to determine whether the acquisition should be put on hold pending a full trial. California and eleven other states opposing the deal want a trial in April next year. If Paramount fails to close the deal by the end of September, it must pay late fees to Warner Bros. shareholders of about seven million dollars per day, potentially totaling over one billion dollars if the trial is delayed until April. The judge found that the states’ case is in the public interest and likely to succeed, increasing the odds of a longer delay. Paramount is expected to appeal if it loses the next ruling, but a decision may not come until the end of the year or later.

Wix.com was downgraded by Morgan Stanley to Equal Weight from Overweight, with the price target cut to sixty dollars from one hundred twelve. While Wix is making progress on its AI strategy through innovations like Harmony and Base44 and recent restructuring, investors are looking for stronger evidence of core website trends and sustainable AI-driven economics before the stock can move meaningfully higher.

xAI announced that it is bringing its Grok AI assistant into Microsoft Excel as a free Microsoft 365 add-in. Users can select a range of cells and ask Grok what moved, why, and what stands out, with answers citing the source cells and charts dropping directly into the sheet. The Grok add-in is available via the Microsoft Marketplace and also works in Word and PowerPoint.

Now, let’s turn to event-driven headlines.

Diageo chair John Manzoni is reportedly planning a board reshuffle, seeking directors with deeper drinks or distribution experience to better challenge new CEO Dave Lewis as he leads a turnaround. The move suggests Manzoni is dissatisfied with the current board and wants a stronger mix of expertise to support restructuring and improve shareholder returns. Lewis has already begun addressing weak North American sales and is considering price cuts on some tequila brands as part of an aggressive effort to revive the struggling spirits group.

Icahn Enterprises has struck a deal to sell auto-service chain Pep Boys to Mavis Tire Express Services for roughly seven hundred million dollars in cash. A subsidiary of Mavis will take over the business from a subsidiary of Icahn Enterprises, which will retain some owned real estate and other auto service businesses, including AAMCO Transmissions and Precision Tune Auto Care.

Jersey Mike’s Subs and its shareholders are looking to raise as much as one point zero nine billion dollars in an initial public offering, as consumer-oriented companies join the US listing rebound. The company plans to market about forty-three point five million shares for twenty-one to twenty-five dollars each, including nearly thirty million shares from shareholders such as Blackstone and the Abu Dhabi Investment Authority. At the top of the range, Jersey Mike’s would have a market value of nearly eight billion dollars.

The London Stock Exchange is set to open a new trading venue outside of regular market hours, aiming to offer near-continuous trading and better compete with the twenty-four-seven trading offered by crypto platforms. The new venue, called LSE 24, will operate from five p.m. to seven fifty a.m. in London and is expected to be ready for client testing by the end of twenty twenty-six. Exchange-traded products will be the first assets available on the platform, with trading expected to begin in the first half of twenty twenty-seven.

Magnolia Oil & Gas has agreed to acquire WildFire Energy for about four point one billion dollars, including debt, expanding its presence in the Eagle Ford Shale basin of south Texas. WildFire owners will receive thirty-two point two million shares of Magnolia’s Class A common stock, and Magnolia will assume six hundred million dollars of outstanding notes due in twenty twenty-nine. WildFire is backed by private equity firms Warburg Pincus and Kayne Anderson Capital Advisors, and the deal is expected to close late in the third quarter.

OCS Group International has agreed to buy rival Mitie Group for three point one billion pounds, or about four point two billion dollars, combining two of Britain’s largest facilities management companies. OCS will pay two hundred twenty-one point six pence per Mitie share, including a final dividend payment, representing a near forty-seven percent premium to Mitie’s closing price on Monday. The deal would expand the geographic reach of both UK-headquartered businesses, giving the combined company revenue of about eight point five billion pounds. Both boards are backing the deal, and shares of Mitie rose as much as forty-two percent early Tuesday in London.

Let’s take a look at some key charts and data points shaping the markets.

In the United States, assets under management in levered exchange-traded funds have dropped by over one hundred billion dollars, with sixty-three billion dollars of that coming out of semiconductor-focused funds, according to Goldman Sachs.

On the equities side, margin debt as a percentage of GDP is near all-time highs, but as a percentage of market capitalization, it is just getting back toward the middle of the post-2010 range, based on data from Variant.

Earlier in the artificial intelligence cycle, hyperscalers drove more growth, but in the second quarter, semiconductors are expected to generate nearly half of S&P 500 earnings growth, according to JP Morgan.

Bank stocks are again providing a rotational cushion for the broader market as the momentum unwind continues, according to Strategas.
