Most readers would already be aware that Intuitive Surgical's (NASDAQ:ISRG) stock increased significantly by 10% over the past three months. Given that the market rewards strong financials in the long-term, we wonder if that is the case in this instance. Specifically, we decided to study Intuitive Surgical's ROE in this article.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How To Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Intuitive Surgical is:

14% = US$2.3b ÷ US$16b (Based on the trailing twelve months to September 2024).

The 'return' is the yearly profit. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.14 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company's earnings growth potential. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don't share these attributes.
