When Good Things Are Actually Bad

So Federal Reserve Chairman broke into the trading day to lower interest rates a half point, a large move as rate-raising goes and the markets did the unexpected:  a reasonably good day given yesterday's huge move up turned negative.

Why?  Because the Chairman gave as his reason the concern surrounding Corona.  If he had to act so quickly and so vividly, things must be bad, no?

The Fed has suffered a withering attack from the White House about its reluctance to lower interest rates.

Was this a way for the Fed to give in to that pressure while at the same time hurting the administration by the way it did the cut?  Ah, politics!
