Historically, the PE for the entire
U.S. stock market is about 15. But
today’s market PE of roughly 23 is
about 50 percent higher than the
historic average
Every time I see statements about the PE of the market, I wonder which PE they mean?The price of the companies divided by their past revenue? If so, which past? Last month, last quarter, last year?
The price of the company divided by future revenue? Then future revenue guessed by whom and for which time frame?
