No, a stock split does not inherently increase the value of shares or a company’s valuation. If a company decides to split shares in half, for example, each individual share would be worth half its initial value. Therefore, they do not change valuation on their own. However, more subjective factors regarding stock splits can impact valuation. For example, the decreased price for one share may attract would-be investors who previously were priced out of the stock. Additionally, hype, market sentiment and perception around a stock split may have the potential to attract investment.
