Concedes Einhorn is correct on a relative basis, as markets get more expensive yearly. Argues this year is unique: earnings growth is accelerating, ISM is above 50, and the market concludes the new Fed is dovish. Points out the market survived multiple 'black swans' and still grew earnings, suggesting it deserves a higher P/E, just as gold is being re-rated.
References gold's high price-to-sales multiple (~50x) as an example of re-rating that equities could follow.
