Bloomberg with a piece up on Goldman Sachs asking if stock are overvalued:

To answer the question, the bank pits Nobel laureate Robert Shiller and Wharton professor Jeremy Siegel against each other

GS examines the question with respect to expectations of Fed hikes coming soon, what this will do to equity valuations and so on.

It's a good read and is ungated: Goldman Sachs Asked Two of the World's Best-Known Economists If U.S. Stocks Are in a Bubble

The economists they ask disagree ... (what else is new?) .... but do find common ground on the bond market:

  • Both economists said it was fair to say bonds are overvalued and some concern is justified, although neither of them would commit to calling it a bubble. Shiller said that historically the bond market doesn't tend to crash like the stock market. Siegel steered away from calling it a bubble due to his expectation that both short- and long-term rates will remain low.
