Rio Tinto plc (NYSE:RIO) and Maxim Integrated Products, Inc. (NASDAQ:MXIM) are the two most active stocks in the market based on today’s trading volumes. The market is clearly enthusiastic about both these stocks, but which is the better investment? To answer this, we will compare the two companies based on the strength of their growth, profitability, risk, returns, valuation, analyst recommendations, and insider trends.


The ability to consistently grow earnings at a high compound rate is a defining characteristic of the best companies for long-term investment. Analysts expect RIO to grow earnings at a 16.80% annual rate over the next 5 years. Comparatively, MXIM is expected to grow at a 15.02% annual rate. All else equal, RIO’s higher growth rate would imply a greater potential for capital appreciation.

Profitability and Returns

A high growth rate isn’t necessarily valuable to investors. In fact, companies that overinvest in low return projects just to achieve a high growth rate can actually destroy shareholder value. Profitability and returns are a measure of the quality of a company’s business and its growth opportunities. We’ll use EBITDA margin and Return on Investment (ROI) to measure this. EBITDA margin of 37.63% for Maxim Integrated Products, Inc. (MXIM). RIO’s ROI is 17.30% while MXIM has a ROI of 15.90%. The interpretation is that RIO’s business generates a higher return on investment than MXIM’s.

Cash Flow 

If there’s one thing investors care more about than earnings, it’s cash flow. On a percent-of-sales basis, RIO’s free cash flow was 0% while MXIM converted 3.61% of its revenues into cash flow. This means that, for a given level of sales, MXIM is able to generate more free cash flow for investors.

RIO is the cheaper of the two stocks on an earnings, book value and sales basis. Given that earnings are what matter most to investors, analysts tend to place a greater weight on the P/E.

Analyst Price Targets and Opinions

Just because a stock is cheaper doesn’t mean there’s more value to be had. In order to assess value we need to compare the current price to where it’s likely to trade in the future. RIO is currently priced at a -14.53% to its one-year price target of 60.89. Comparatively, MXIM is 1.72% relative to its price target of 61.14.
