((My votes...))
A half-point?? That would not lead to stable prices, and could directly be "challenged" as not maximizing employment -- so I'll vote "no."
Yellen's yellin' similar to December?? I wanna vote "Yes" in a big way, but with those "key words" missing or reversed. Just a couple, but the text-reading machines will go nuts on them. But while 'extracurricular' economic distractions abound (Russia, NK, the Orange-utan), we have continued base-building worldwide, slowing cries of "Disaster!" in China (whether credible or not, *I* don't know...), and both a need, and an opportunity, to get away from ZIRP-dom. In short? "We're due. Here it is. More comin'."
To make the market go up?? Wow. That's a toughie. With this morning's news, we're just about at the place where "Good news is good (again); bad news is bad." If the market is looking for re-assurance, perhaps words like, "FOMC consensus is that maintaining stable prices will best be accomplished by following the federal government's lead in tax policy re-structuring..." which is to say, "We won't raise again, until tax reform is __completed__."
THAT would send *quite* the message.
What would make the market go down? That one is much easier.
"Unified-party government has historically led to fiscal run-aways and vicious inflation, and to get in front of the issue, we're going to raise rates every two months for the next year."
("Jinkies!")
Thems me votes, at any rate.
