Share buyback programs are typically viewed positively by the market as they often lead to an increase in the stock price. By reducing the number of shares available in the market, each share represents a larger ownership stake in the company, potentially increasing its value. Given the substantial amount allocated for the buyback, this indicates strong confidence from Equinor's management in the company's financial health and future prospects. The detailed plan and significant investment suggest a positive short-term impact on Equinor's stock price.
