Stock price increase
股票涨幅用英文可以说成 "stock price increase" 或者 "stock appreciation"。如果你想要更具体地表达某个股票从某个价格涨到另一个价格,可以说 "the stock has risen by X%" 或者 "the stock has appreciated by X% from its original price"。比如,如果一支股票从10美元涨到15美元,你可以说 "The stock has risen by 50% from its original price of $10 to the current $15." 或者 "The stock has appreciated by 50% since it started at $10."
