Isn't Powell coming out and essentially stating that the Fed is not likely to raise rates -- perhaps even lower them -- in 2019 a factor in the current upswing?

The minutes released today from the mid-December Fed meeting make for an interesting read.

Also, isn't the 'umpteenth' rumor that the U.S.-China trade spat is showing signs of being on the mend (as uncorroborated as those rumors may be) also creating a bullish reaction from the markets?
