Stocks were mixed on Wednesday after weaker-than-expected inflation data showed the cost of wholesale goods and services fell in August, giving the Federal Reserve all the more reason to cut interest rates next week.

These stocks were making moves:

Klarna climbed 17%. The Swedish fintech made its trading debut on Wednesday, when a total of 34.3 million shares began trading on the New York Stock Exchange under the ticker KLAR. The stock opened at $52, or 30% above the $40 a share Klarna's underwriters priced on Tuesday evening.

Oracle surged 39%. While the software company missed Wall Street's targets for quarterly earnings and revenue, it reported a significant increase in its backlog of contracted work, signaling intense demand for renting artificial-intelligence servers in the cloud. Fellow AI cloud company CoreWeave rose 19%, AI chip maker Advanced Micro Devices gained 2.7%, and networking-equipment company Arista Networks was up 6.3%. Palantir Technologies also got a boost on the back of Oracle's earnings, rising 3.1%.

GameStop jumped 6.4%. The videogame retailer posted fiscal second-quarter adjusted earnings of 25 cents a share on revenue of $972.2 million after the closing bell Tuesday.

Synopsys plunged 35% after the chip design software company reported weaker-than-expected earnings and revenue for its fiscal third quarter, and issued mixed guidance for the current quarter. Synopsys said it expects adjusted earnings of $2.78 a share on sales of $2.25 billion, compared to analysts' calls for $4.50 a share on sales of $2 billion.

Wolfspeed sank 19% after ending the session up 48% on Tuesday. The company said Monday that its reorganization plan had been approved in bankruptcy court, and that it planned to emerge from Chapter 11 protection "in the next several weeks."

Shares of Wearable Devices, the maker of AI-powered touchless wristbands, soared 562% after the company said its loss per share had narrowed to $2.30 from $16.52 in the first half of the year. However, revenue also fell to $294,000 from $394,000 a year ago.

AeroVironment was up 2.1%. The defense contractor raised its profit outlook for the year after revenue mo3re than doubled in its fiscal first quarter. Earlier this week, the company said it had received a nearly $240 million order for long-haul laser communications terminals.

Shares of Rubrik fell 15%, even after the data-security company reported a considerably narrower-than-expected quarterly loss and revenue topped forecasts. Rubrik posted an adjusted loss of 3 cents a share, narrower than the 35-cent loss Wall Street had expected. Revenue rose 51% to $310 million in the quarter, handily beating the $282.2 million analysts anticipated.

Chewy declined 17%. The online pet-products retailer posted second-quarter earnings of 33 cents a share, in line with Wall Street forecasts, and sales of $3.1 billion that beat the $3.08 billion consensus estimate among analysts polled by FactSet. The company also raised its full-year revenue guidance to a range of $12.5 billion to $12.6 billion, up from $12.3 billion to $12.45 billion. Analysts were looking for $12.495 billion.

Earnings reports are also expected Wednesday from Daktronics and Oxford Industries.
