U.S. large-cap stocks notched new record highs on Tuesday, pushing the S&P 500 past the 2,600 level on an intraday basis for the first time ever, in relatively quiet trading. Felt like machine-driven, central-bank funded algorithmic demand with a gap and rise at the open with nary a hint of volatility or texture. Everywhere you look, there was froth to be seen. The cryptocurrency market is red hot, undisturbed by reports of thefts and frauds. The art market is out of control.
