The stock of a company with a growth rate twice the market would be expected to have a:

A company with a growth rate that is twice that of the market is likely to attract higher investor interest due to its anticipated future earnings potential. This expectation of robust growth leads investors to be willing to pay a premium for the company's shares, resulting in a higher price-to-earnings (P/E) ratio compared to the overall market.

The P/E ratio reflects what investors are willing to pay today for a dollar of expected future earnings. A growth rate that significantly outpaces the market implies that the company is expected to generate more earnings in the future compared to its peers. As a result, if investors believe that this company's future earnings growth justifies a higher valuation now, they tend to drive up the share price relative to current earnings, which results in a higher P/E ratio.

In contrast, companies that grow at rates similar to or lower than the market may have P/E ratios that are closer to the market average or lower. This is why a company with a higher-than-market growth rate would notably exhibit a higher P/E ratio.
