Earnings reports are critical events for investors as they provide insight into a company's financial health and future prospects. A worse-than-expected earnings report and a less optimistic future outlook can lead to a decrease in investor confidence, resulting in a decline in the stock price. Given that Kontoor Brands has reported both disappointing Q4 earnings and a bleak forecast for FY24, it is likely that investor sentiment will be negatively impacted in the short term, leading to a decrease in the stock price.
