Nike stock: does Tim Cook’s purchase make NKE a buy at current valuations?

Apple CEO Tim Cook sent a powerful signal Wednesday when he spent nearly $3 million to nearly double his stake in Nike stock (NYSE: NKE), just one day after the athletic-wear company reported a devastatingly weak earnings report.

The purchase, 50,000 shares at $58.97 each, marked Cook’s first-ever open market stock buy in his 20 years on Nike’s board, a notable departure from his previous acquisitions, which came via compensation or equity grants.

Nike stock surged 4.6% to close around $60, making it the S&P 500’s biggest gainer on Christmas Eve.​

Nike stock: What Tim Cook’s purchase actually signals

Cook’s timing was striking. He bought just hours after Nike reported earnings that shocked Wall Street.

The company posted earnings per share of $0.53, a stunning 32% plunge from the prior year, while gross margins collapsed 300 basis points to 40.6%.

Revenue barely grew, hamstrung by a 9% decline in Nike’s direct-to-consumer business and heavy promotional discounting.

For Cook to step up and buy in the wreckage signals one of two things: either he sees panic selling that doesn’t reflect reality, or he has conviction in CEO Elliott Hill’s turnaround plan despite near-term headwinds.​

The mechanics matter. Cook is Nike’s lead independent director and orchestrated Hill’s return from retirement in October 2024.

By buying 50,000 shares and raising his holdings to 105,480, worth roughly $6.2 million, Cook is betting his personal capital on a strategy he championed.

Notably, another Nike director, Robert Swan (former Intel CFO), also bought on the dip, spending $500,000 for 8,691 shares at $57.54.

Yet insider buying doesn’t always signal bottoms.

Holiday-thin trading volumes can exaggerate moves, meaning Wednesday’s 4.6% rally might reverse quickly once real money returns in January.​

Is Nike stock a buy now?

Nike’s valuation looks deceptively cheap until you dig deeper.

At a trailing price-to-earnings ratio of 35.25, the stock appears expensive compared to the Consumer Cyclical sector average of 18.86.

But that high multiple reflects cratered earnings. Looking forward, Nike trades at 31.27x forward earnings, which is more reasonable, though still elevated for a company guiding to margin compression in the next quarter.​

The bull case rests on Hill’s ability to stabilize margins and rebuild wholesale partnerships with Foot Locker and Dick’s Sporting Goods, which Nike alienated between 2020 and 2023.

The 2028 Los Angeles Olympics could provide a multi-year marketing tailwind for performance products.

If Hill can restore Nike’s product credibility and full-price sell-through, the stock could re-rate to its historical 25x average multiple, implying upside if earnings recover.​

But the risks are structural. Tariffs alone will drag gross margins by 320 basis points in fiscal 2026, with Nike estimating $1.5 billion in annualized product costs.

China’s demand remains sluggish. Moody’s downgraded Nike’s debt rating in November. Hill himself told investors the turnaround “will take a while” with “no straightforward path.”​

For short-term traders, Cook’s purchase is a momentum trigger worth trading. For long-term investors, it’s a positive signal, but it doesn’t seem to be a buy button.
