Sirius XM Holdings Inc. (NASDAQ:SIRI) and Merck & Co., Inc. (NYSE:MRK) are the two most active stocks in the Broadcasting – Radio industry based on today’s trading volumes. Investors are clearly interested in the two names, but is one a better choice than the other? We will compare the two companies across growth, profitability, risk, valuation, and insider trends to answer this question.


The ability to grow earnings at a compound rate over time is a crucial determinant of investment value. Analysts expect SIRI to grow earnings at a 22.29% annual rate over the next 5 years. Comparatively, MRK is expected to grow at a 9.54% annual rate. All else equal, SIRI’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., compared to an EBITDA margin of 24.61% for Merck & Co., Inc. (MRK). SIRI’s ROI is 22.30% while MRK has a ROI of 8.70%.

This means that, for a given level of sales, SIRI is able to generate more free cash flow for investors.

Liquidity and Financial Risk

Analysts look at liquidity and leverage ratios to assess how easily a company can cover its liabilities. SIRI has a current ratio of 0.20 compared to 1.30 for MRK. This means that MRK can more easily cover its most immediate liabilities over the next twelve months.

SIRI is the cheaper of the two stocks on book value basis but is expensive in terms of P/E and P/S ratio. 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. SIRI is currently priced at a -8.16% to its one-year price target of 6.86. Comparatively, MRK is -5.11% relative to its price target of 79.12. This suggests that SIRI is the better investment over the next year.

Conversely, a beta below 1 implies below average systematic risk. SIRI has a beta of 1.05 and MRK’s beta is 0.72. MRK’s shares are therefore the less volatile of the two stocks.
