Another View: Sizing Up Valuation Using Ratios

While some see Monolithic Power Systems as undervalued, a look at its price-to-earnings ratio tells a more complex story. At 25.4x, it is cheaper than the US semiconductor industry average of 36.1x or peers at 37.2x. It still trades above its fair ratio of 23.2x, which could mean there is less room for upside if expectations cool. Does the market believe profits can keep pace with the premium?
