These ASX 200 shares jumped 15% or more in February

The S&P/ASX 200 Index (ASX: XJO) was on form in February and managed to carve out a gain of 3.7%.

While that was strong, some ASX 200 shares delivered far more for their lucky shareholders.

Here's why these shares jumped more than 15% last month:

BHP Group Ltd (ASX: BHP)

The BHP share price surged 15.5% in February. Investors were buying the mining giant's shares following the release of its half-year results. BHP reported an 11% increase in revenue to US$27.9 billion and a 25% lift in underlying EBITDA to US$15.46 billion. A key driver of this growth was its copper operations, which reported record EBITDA of US$8 billion. This meant that copper contributed the majority of earnings for the first time in its history. Another positive was news that BHP has entered into a long-term streaming agreement with Wheaton Precious Metals Corp. (NYSE: WPM). The Big Australian will receive an upfront payment of US$4.3 billion. In exchange, it will deliver Wheaton a share of silver produced at the Antamina mine in Peru. This agreement represents the most valuable streaming transaction to date based on the upfront consideration.

Commonwealth Bank of Australia (ASX: CBA)

The CBA share price raced 17% higher during the month. Australia's largest bank impressed the market with its half-year results in February. For the six months, CBA reported a 6% increase in cash net profit to $5,445 million and lifted its fully franked interim dividend by 4% to $2.35 per share. CBA's CEO, Matt Comyn, said: "Economic growth strengthened during the half, driven by increases in consumer demand and rising investment in AI and energy infrastructure."

Lynas Rare Earths Ltd (ASX: LYC)

The Lynas Rare Earths share price was on fire and rocketed 27% in February. This followed the release of the rare earths producer's half-year results. Lynas posted a 63% increase in revenue to $413.7 million and net profit after tax of $80.2 million. The latter compares to a profit of just $5.9 million a year earlier. The company's CEO and managing director, Amanda Lacaze, said: "The December half of FY2026 was an exciting one for Lynas. We completed commissioning for the Mt Weld expansion project, delivered the first half year of Heavy Rare Earth production at Lynas Malaysia, launched the Towards 2030 growth strategy and successfully completed an equity raising to support our growth agenda."

PLS Group Ltd (ASX: PLS)

The PLS share price rose 21% during the month. This was driven by the release of a strong half-year result from the lithium miner. PLS' revenue jumped 47% to $624 million and its underlying EBITDA surged 241% to $253 million. This was driven by a combination of higher production volumes, lower costs, and a rebound in lithium prices. PLS' managing director and CEO, Dale Henderson, said: "PLS delivered a strong first half, generating Underlying EBITDA of $253 million at a 41% margin reinforcing our low cost position and ability to generate positive EBITDA through the cycle. The result was driven by higher realised pricing, reliable operating performance and continued cost discipline, with unit operating costs declining 8% to $563 per tonne (FOB)."
