Is this peak insanity?

With current market valuations now exceeding those of 1929, and even of 1999, the term ‘peak insanity’ is coined. Arnout van Rijn, CIO Asia Pacific, is less concerned. “It is not as bad as 1999. It's just a small segment of the market that is really at multiples that are hard to defend. The bigger segment of the market that now trades at relatively elevated multiples are just healthy cash flow-positive stocks that the market is willing to pay up for because of the TINA argument – ‘there is no alternative’.
