In a move that reflects a growing trend among mega corporations, Nvidia has become the eighth company this year to announce a forward stock split, potentially paving the way for other high-priced S&P 500 stocks to follow suit. While stock splits have no direct impact on a company's market value or fundamental health, history suggests they can be a bullish signal for investors.

Bank of America, in its analysis, has found that stock splits historically result in average returns of 25% one year later, compared to the broader market's average of 12%. This finding holds true across various market regimes, making stock splits an attractive option for management teams when shares appear prohibitively expensive for buybacks.

Forward stock splits are often seen as a sign of strength, as they tend to align with rising stock prices that reflect the growing profits of the underlying business. Additionally, high stock prices can create accessibility barriers, making it difficult for employees and retail investors to invest in these companies. This accessibility concern was cited as a main reason by both Walmart and Nvidia for their decision to enact a stock split.

Nvidia's forward stock split will see the company offering nine additional shares for every share owned. As a result, its current stock price of more than $1,000 per share will trade at just above $100 per share from June 10 when the split goes into effect. This move is expected to increase liquidity and make the shares more accessible.

Bank of America has identified approximately 36 companies in the S&P 500 index with a combined market value of $7.4 trillion that may be candidates for stock splits. These companies have stock prices above $500 per share. Moreover, there are eight S&P 500 companies with share prices exceeding $1,000 per share that are even more likely to pursue stock splits.

While it should be noted that stock splits themselves do not directly impact a company's fundamentals, they serve as a positive market signal. As more companies consider splitting stocks to improve accessibility and increase liquidity, investors will be watching closely for potential opportunities in the market.

As the trend of stock splits continues to gain momentum this year, it remains to be seen which high-priced S&P 500 stocks will follow in Nvidia's footsteps and embark on their own bullish journey.
