What is the formula for determining estimated stock price when I  only have an earning per share number?
What you need to do is go to yahoo finance and look at different stock's P/E ratios. You'll quickly see that the stocks can be sorted by this number. It would be an interesting exercise to get an idea of why P/E isn't a fixed number, how certain industries cluster around a certain number, but even this isn't precise. But, it will give you an idea as to why your question has no answer. "Annual earnings are $1. What is the share price?" "Question has no answer"
