The significance of cash per share is that it links a company's cash holdings with shareholders' equity, thus providing investors with a more intuitive reference indicator. Higher cash per share usually means that the company has stronger liquidity and can better cope with short-term debt or invest in expansion. However, too high cash per share may also indicate that the company has failed to effectively use cash resources, so it is necessary to combine other financial indicators, such as asset turnover, to judge its operating efficiency. In addition, the reasonable level of cash per share may vary between companies in different industries and at different stages of development, so caution is needed when making horizontal comparisons.
