Parasomethingorother!  P/E ratio is a backward or historical number unless addressed as a forward P/E in other words it can be affected by about anything!  For example I am a mine running my last resource through the mill the stock price would be really low knowing this is the last year of production, however the P/E would be fantastic!  Using P/E in the mining world can be very dangerous and often very meaningless hence the stock price!  It serves you well to understand how things work!
