In the first quarter of the 2026 fiscal year, Credo Technology Group Holding Ltd (NASDAQ:CRDO) swung to a net profit of $63.4 million from a $9.54 million net loss in the same period last year, as total revenues skyrocketed by 273.6 percent to $223.07 million from $59.7 million, on the back of a jump in product sales revenue.

At the 2025 Wells Fargo Healthcare Conference in Boston, Massachusetts, held last September 3 to 5, Oscar Health, Inc. (NYSE:OSCR) reaffirmed its key growth metrics for the full year, including a revenue growth guidance of $11.2 billion to $11.3 billion and operating income of $225 million to $275 million.

6. Wayfair Inc. (NYSE:W)

Wayfair jumped by 20.12 percent week-on-week to hit a new all-time high as investor sentiment was bolstered by the company’s optimistic business outlook.

At the recently concluded Goldman Sachs Global Retailing Conference, Wayfair Inc. (NYSE:W) CEO Niraj Shah said that he believed in the company’s growth potential despite cyclicality and that it would gain a market share amid the industry’s fragmented nature.

“The way we look at it is…it’s a cyclical category, but our view is, with our model, we can take share in a down market, and we can take even more share in an up market,” he said.

“We don’t view the cyclicality of it as something that should restrain our ability to grow. While the market is…not a growth market from the total addressable market growing standpoint, the truth is…there’s a large number of participants, and it’s very, very fragmented. The ability to take share is actually a very real thing because…it’s a category that has a lot of passion and excitement in it,” he added.

At present, Wayfair Inc. (NYSE:W) is underway with the expansion of its physical stores, one targeted to open in Atlanta next year, with another large-format version expected to open at Ridge Hill in Yonkers, New York.

Wayfair Inc.’s (NYSE:W) brick-and-mortar expansion plans mark a vote of confidence despite the United States’ trade spat with China, where it sources a significant chunk of its supplies.

5. Celestica Inc. (NYSE:CLS)

Celestica saw its share prices soar by 24.6 percent week-on-week, as investor optimism from semiconductor giant Broadcom Inc. spilled over to its stock.

During the trading week, Celestica Inc. (NYSE:CLS) rallied for four straight days to touch a fresh 52-week high of $257.4 on Friday before trimming gains to end the day at $242.68.

Friday’s session mirrored the rally in shares of Broadcom, one of its largest customers, after the latter reported stellar earnings performance and clinched a new $10-billion custom chip supply deal with OpenAI.

Optimistic investors highly anticipated the new deal to largely benefit Celestica Inc. (NYSE:CLS) in terms of revenues, having been a longtime manufacturing and supply chain partner of the semiconductor giant.

In recent news, Celestica Inc. (NYSE:CLS) announced a 122-percent jump in its net income in the second quarter of the year, at $211 million versus $95 million in the same period last year. Revenues grew by 21 percent to $2.89 billion from $2.39 billion year-on-year.

4. Sandisk Corp. (NASDAQ:SNDK)

Sandisk rallied by 30.65 percent week-on-week to hit a new all-time high after marking three straight days of gains as investor sentiment was boosted by the broader market optimism for Artificial Intelligence.

On Friday alone, Sandisk Corp. (NASDAQ:SNDK) surged to its highest 52-week record of $68.67, marking a 9.87-percent jump, before paring gains to finish the day up by only 9.68 percent at $68.55.

The rally was mainly influenced by Morgan Stanley’s bullish comments for the NAND memory market, citing strengthening fundamentals.

According to the investment firm, the enterprise SSD had grown sharply, largely driven by increasing AI infrastructure buildouts and ongoing HDD shortages.

Massive orders—totaling tens of exabytes—are moving NAND supply away from consumer markets such as PCs and smartphones.

While Sandisk Corp.’s (NASDAQ:SNDK) exposure to enterprise SSD was limited, Morgan Stanley expects upside for the company as its BICS 8 process ramps up in the second half of the year, positioning it for a better 2026.

3. Macy’s Inc. (NYSE:M)

In an updated report, Macy’s, Inc. (NYSE:M) said it achieved net sales of $4.8 billion in the second quarter of the year, exceeding its own guidance. However, the actual figures were lower by 2 percent than the $4.9 billion in the same period last year.

Additionally, Macy’s, Inc. (NYSE:M) said it saw a 1.1 percent uptick in comparable sales growth for 125 revamped locations.

Net income, on the other hand, fell by 42 percent to $87 million from $150 million in the same period last year, as a result of the store closures earlier this year. Revenues dipped by 1.9 percent to $4.999 billion from $5.096 billion in the same period last year.

“Our teams achieved better than expected top and bottom-line results during the second quarter, driven by our strongest comparable sales growth in 12 quarters, reflecting the strong performance in Macy’s Reimagine 125 locations, Bloomingdale’s, and Bluemercury,” said Macy’s, Inc. (NYSE:M) Chairman and CEO Tony Spring.

Shares of American Eagle jumped by 45.36 percent week-on-week as investors cheered its beating of its second-quarter business outlook.

In its updated report, American Eagle Outfitters, Inc. (NYSE:AEO) said net revenues dipped by almost 1 percent to $1.28 billion from $1.29 billion in the same period last year. However, the dip was surprisingly lower than the company’s expected 5 percent drop in revenues.

Additionally, comparable sales decreased by 1 percent but were notably better than the 3-percent drop projected previously.

“We were pleased to see an improvement in the business during the second quarter, driven by higher demand, lower promotions, and well-managed expenses, all of which exceeded our expectations,” said American Eagle Outfitters, Inc. (NYSE:AEO) CEO Jay Schottenstein.

“The actions we have taken to better align inventory and strengthen execution laid the groundwork for our results this quarter…We look forward to building on our progress and the continued strength of our iconic brands to drive higher profitability, long-term growth, and shareholder value,” he added.

1. Opendoor Technologies Inc. (NASDAQ:OPEN)

Opendoor Technologies skyrocketed by 49.44 percent in just the past four trading weeks, hitting a new all-time high, as investors bought into a hedge fund’s campaign to bring back the former’s co-founder to the board to support business revival.

On Friday, Opendoor Technologies Inc. (NASDAQ:OPEN) touched a fresh 52-week high of $6.85 before trimming gains to end the day just up by 11.58 percent at 6.65 apiece.

Investors rallied behind a campaign by Eric Jackson—who owns a significant stake in the company—to bring back Keith Rabois to the board, believing that his bold, aggressive, and visionary, would support the company’s turnaround and revival.

Rabois’ business strategy compared with Opendoor Technologies Inc.’s (NASDAQ:OPEN) former CEO, Carrie Wheeler, who was more cautious and reactive.

In a post on X (formerly Twitter), Jackson said he believed the company could propel to as high as $82, $200, and even $500, but that the current board “will be long gone by then.”

Further spurring sentiment were high expectations of a lower interest rate at the Federal Reserve’s next FOMC meeting.

Opendoor Technologies Inc. (NASDAQ:OPEN), a real estate technology company that resells residential properties, is expected to benefit from the move on lower borrowing costs for prospective homebuyers.
