can pe ratio of stocks be compared to other investments?
user
yes, there are non-stock analogs to the price/earnings ratio. rental properties have a price/rent ratio, which is analogous to stocks' price/revenue ratio.  with rental properties, the "cap rate" is analogous to the inverse of the price/earnings ratio of a company that has no long-term debt. bonds have an interest rate.  depending on whether you care about current dividends or potential income, the interest rate is analogous to either a stock's dividend rate or the inverse of the price/earnings ratio.
