Nike Stock Soars After CEO Soothes Investors, Says Recovery Is on the Horizon

Nike stock soared 20.5% this week as the company said the worst of its struggles are behind it, following a better-than-feared fiscal fourth-quarter earnings report. 

Nike on Thursday reiterated it would take the biggest financial hit from its turnaround plan during the quarter, soothing investors who worried President Donald Trump’s tariff hikes on key Nike manufacturing hubs like China and Vietnam would derail the company’s comeback.

Nike posted a poor fourth quarter, as sales dropped 12%, net income plunged 86% and profit margins dwindled. But CEO Elliott Hill stressed the company has emerged from the worst of its slump, and the slide in sales and profits would begin to moderate in the quarters ahead.

Arista Networks Shares Surge on Analyst Upgrade

Networking equipment maker Arista Networks surged 15.2% this week. There are 17 analysts recently revising their earnings expectations upward.

Evercore ISI raised its price target on Arista Networks to $110.00 from $105.00 on Monday, while maintaining an Outperform rating on the networking equipment maker. The firm cited multiple near-term catalysts that could drive the stock higher, including an expected revenue guidance raise to at least 20% when Arista reports second-quarter results.

KeyBanc initiated coverage on Arista Networks stock Wednesday with an overweight rating and a price target of $115.00.

Carnival Shares Jump on Earnings Beat and Raised Full-Year Outlook

Carnival shares jumped 14.7% this week as the cruise line posted stronger-than-expected second-quarter results and raised its full-year guidance.

According to the company's earnings report, the cruise operator posted adjusted earnings of 35 cents per share while beating analysts' estimates of 24 cents, according to LSEG. Adjusted revenue came in at a record $6.3 billion compared with the expected $6.2 billion.

Net income rose to $565 million, which was a significant increase from $92 million a year ago.

Due to outperformance, Carnival raised its full-year guidance and said it now expects adjusted net income to be 40% higher than 2024, which is about $200 million more than its March forecast.

Meanwhile, the cruise line said it expects full-year adjusted earnings before interest, taxes, depreciation and amortization, or EBITDA, to be $6.9 billion, up from a prior estimate of $6.7 billion.

Coinbase Stock Soars on Regulatory Clarity and a Bernstein Price Target Boost

Coinbase shares soared 14.6% this week as the company benefits from increased national and global regulatory clarity, as well as a price target boost from a major investment research firm. 

The stock price of the largest crypto exchange in the U.S. has surged 38% since June 18, after the U.S. Senate passed the first bill to establish a regulatory framework for stablecoins, a type of cryptocurrency pegged 1:1 to the U.S. dollar.

The crypto exchange’s stock was further lifted on June 20 after becoming the first U.S. exchange to receive regulatory approval in the European Union (EU). Coinbase received its Markets in Crypto Assets (MiCA) license in Luxembourg, allowing the exchange to offer crypto services in all 27 EU member states. 

In addition to recent regulatory tailwinds, investors rushed to buy Coinbase after a Wednesday report from Bernstein, a global equity and research brokerage firm, in which analyst Gautam Chhugani lifted the stock’s price target by the end of 2027 from $310 to $510, a 65% increase. Price targets are projections of a stock’s future price made by financial analysts that often shape investors’ expectations and influence market sentiment. 

Enphase Energy Surges on Solar Tax Credit Optimism

Enphase Energy shares surged 14% this week following reports that the U.S. Senate may not cut federal tax incentives for residential rooftop solar installations.

Solar stocks have rallied this week after Senator Kevin Cramer said on Tuesday that Republicans on the tax writing committee were considering making a slate of clean energy tax credits more generous, including by pushing back expiration dates, and adding that lawmakers also were discussing changes for rooftop solar credits.

AMD Shares Surge After Analysts Say They Expect a "Snapback" for Chipmaker

AMD shares surged 12.1% this week.

Analysts at Piper Sandler wrote in a note on Monday that they expect a snapback for AMD’s GPU business in the fourth quarter.

That’s when the analysts expect the chipmaker should be through the bulk of the $800 million in charges that AMD said it would incur due to exports to China.

Last week, AMD unveiled a full-server rack called Helios that enables thousands of the chips to be tied together. The firm cited Arista’s leadership position in cloud and data center networking, highlighting its industry-leading organic growth that has been compounding for the past decade and is expected to continue.

Generator Stock Generac Shines Amid Heat Wave, Looming Storm Threats

Generac shares jumped 11.8% this week.

With hurricane season underway and an oppressive heat wave rolling across parts of the nation, investors have been snapping up shares of Generac.

High temperatures blanketed areas through the central and eastern U.S. starting last weekend, resulting in reported power outages in states such as New York, New Jersey and Illinois. Extreme heat warnings and advisories are still in effect for parts of the Mid-Atlantic, Ohio Valley and Southeast, affecting 130 million people, the National Weather Service said.
