Right now, Marriott Intl Inc. MAR share price is at $92.53, after a 0.24% decrease. Over the past month, the stock spiked by 1.63%, but over the past year, it actually fell by 32.34%. With questionable short-term performance like this, and great long-term performance, long-term shareholders might want to start looking into the company's price-to-earnings ratio.

The stock is currently higher from its 52 week low by 98.72%. Assuming that all other factors are held constant, this could present itself as an opportunity for investors trying to diversify their portfolio with Lodging stocks, and capitalize on the lower share price observed over the year.

The P/E ratio is used by long-term shareholders to assess the company’s market performance against aggregate market data, historical earnings, and the industry at large. A lower P/E indicates that shareholders do not expect the stock to perform better in the future, and that the company is probably undervalued. It shows that shareholders are less than willing to pay a high share price, because they do not expect the company to exhibit growth, in terms of future earnings.

Depending on the particular phase of a business cycle, some industries will perform better than others.

Compared to the aggregate P/E ratio of 24.82 in the Lodging industry, Marriott Intl Inc. has a higher P/E ratio of 33.12. Shareholders might be inclined to think that Marriott Intl Inc. might perform better than its industry group. It’s also possible that the stock is overvalued.

P/E ratio is not always a great indicator of the company's performance. Depending on the earnings makeup of a company, investors may not be able to attain key insights from trailing earnings.
