Indicator to track daily stock indexes

For instance, yield is the barometer for return on bonds.

But how would one gauge how expensive a stock market index is? For instance, im looking at PE ratios that track an index, such as the shiller indicator which compiles a RE Ratio for the SP500 - however this is monthly.

Im looking for a daily indicator that shows how expensive the index is on a historical basis.

Various data providers and charting platforms/services publish Price/Earnings and Price/Book ratios on a daily basis. For example, the National Stock Exchange of India publishes such data for all their indices on a daily basis. Here's the link: https://www.nseindia.com/products/co...rical_pepb.htm Other stock exchanges provide such data as well, or you can just ask your data provider for the same. Good luck!
