Share repurchase programs are typically viewed positively by the market as they can indicate that the company believes its stock is undervalued. By reducing the number of shares outstanding, earnings per share (EPS) may increase, potentially making the stock more attractive to investors. Given this, the announcement of a $350 million share repurchase program by Garrett Motion is likely to be seen as a strong vote of confidence in the company's future prospects and financial health, which could lead to a short-term increase in the stock price.
