Yes. Some stock has a high PE ratio while some has a low PE ratio.
Stock with a high PE means the stock price relative to its earning capability is quite high. In an efficient market, technically speaking, the stock price will go down to make it more rational if there is no significant change in its earning. Vice versa, low PE stock may means it is cheaper and is a best buy.
But, one of the most crucial issue we usually measured the PE ratio is with Market Stock Price but relative to its Historical Earning. This historical earning is a past history or record. There maybe some business with a high contibution ( Earnings ) to the company and thus it's profit in the near future. In this case, the PE will goes down as E is bigger. That is the situation of an effecient market where the buyers and sellers know the situation of that stock. A good sensitivity of its price relative to its market demand.
A good measurement of a stock's level of PE is the industry average PE.
