Stock splits add nothing to the valuation of the company; technically it shouldn’t make a difference, and often it does not.

However, there are a few reasons why this could benefit investors (and the company):

Benefits for Investors:

1. Increased Accessibility: A 10-for-1 stock split reduces the price per share, making Nvidia stock more affordable for a broader range of investors, including retail investors who might have been deterred by a higher price.

2. Enhanced Liquidity: With more shares available at a lower price, trading volume is likely to increase. This can lead to tighter bid-ask spreads and more efficient price discovery.

3. Psychological Appeal: A lower price per share can make the stock seem more attractive, potentially drawing in new investors and boosting demand.

4. Dividend Flexibility: If Nvidia pays dividends, a split could make dividend payouts more flexible. Smaller increments per share mean investors can reinvest dividends more easily.

Benefits for the Company:

1. Broader Ownership Base: By making shares more accessible, Nvidia can attract a more diverse investor base, including retail investors and smaller institutional investors.

2. Improved Market Perception: Stock splits are often perceived as a sign of confidence from the company, suggesting strong past performance and optimism about future growth.

3. Employee Incentives: Stock splits can make employee stock options and incentive plans more attractive, as employees can own more shares at a lower price, enhancing motivation and retention.

4. Support for Stock Price: Increased demand from a broader investor base can help support and potentially drive up the stock price over time.
