I wonder if what we're seeing is just accumulated pressure that businesses are letting off, due to the lower regulation of the current administration. Figure that it's been building up for at least 8 years, likely quite a bit more than that. There might be some more room to run.
Where I live in the SE, you can't throw a rock without hitting construction, or a "Now Hiring" sign. Things are going gangbusters, at least for the moment.
That said, a small correction would be good to let off a little pressure and shake out some of the dumb money. I'm not seeing signs of that yet, usually right before we have a correction, all of the economists are saying "There's nowhere to go but up!" and "This Train Ain't Stopping for ANYTHING!!". That's usually a good sign to sell, means that the train ain't stopping, it's going right over a cliff.
I was getting a little leery about the market, but then Trump comes back from Asia with 250 billion in purchases / investment deals.
Same thing in Utah.
