To answer this question, we will compare the two companies across growth, profitability, risk, and valuation metrics, and also examine their analyst ratings and insider activity trends.

All else equal, ROKA’s higher growth rate would imply a greater potential for capital appreciation.

Profitability and Returns

Just, if not more, important than the growth rate is the quality of that growth. Growth can actual be harmful to investors if it comes at the cost of weak profitability and low returns. To adjust for differences in capital structure we’ll use EBITDA margin and Return on Investment (ROI) as measures of profitability and return. EBITDA margin of 11.26% for NeoGenomics, Inc. (NEO). ROKA’s ROI is -68.20% while NEO has a ROI of 1.60%. The interpretation is that NEO’s business generates a higher return on investment than ROKA’s.

Comparatively, NEO’s free cash flow per share was +0.02. On a percent-of-sales basis, ROKA’s free cash flow was -0.06% while NEO converted 0% of its revenues into cash flow.

Analyst Price Targets and Opinions
