One can debate whether QE has benefitted Main Street or Wall Street until one is blue in the face, even though five years later, the answer is perfectly clear to all but the staunchest Keynesians and monetarists (and if it isn't, just pay attention to the 3:30 pm S&P ramp every day). One thing, however, that is undisputed is what the market itself says about where the QE money ends up when it is being spent by its recipients. And that story is so simple even a Keynesian would get it.
Stated briefly, luxury retailers such as Tiffany, Coach and LVMH are now up 500% since the Lehman lows, and about 30% above the prior cycle highs. On the other hand, regular retailers such as Macy's, Kohl's and JC Penney are barely up 100% from the crisis lows, and still more than 30% below the last bubble highs.
And that, in a nutshell, is precisely how the money from QE has been distributed.
