Changes in the DJIA can have a significant impact on businesses. A rising DJIA often reflects a strong economy, which can lead to increased consumer confidence and spending. This can result in higher revenues and profits for businesses. Conversely, a declining DJIA may indicate economic challenges, leading to reduced consumer spending and potential financial difficulties for companies. Additionally, the performance of the DJIA can influence stock prices, affecting a company's ability to raise capital through the stock market.
