There were plenty of cash tips in the "fall" jar, but I suspect that was just customers keeping things interesting (or ignoring the trivia questions altogether).
Sentiment, whether drawn from surveys, coffee shops, or Uber drivers, is one way to gauge the staying power of a rally like this.
Brian Reynolds, chief market strategist at New Albion Partners, has some other gauges.
In fact, Reynolds canceled his vacation this week to alert clients to the powerful bullish developments he saw forming.
It's a bit wonky, but indexes representing credit-derivative spreads, which represent a type of hedge or insurance investors pay for their investment- grade corporate-bond exposure, have plunged to near-cycle lows.
Meanwhile, the spread between riskier "junk" corporate bonds and "risk-free" U.S. Treasurys has dropped since the election even though interest rates generally are rising. That means investors are less concerned about losing their money on lower-quality corporate debt.
Strong credit markets give companies borrowing options to boost their stock prices, while making bearish investors scramble to close out trades before losing any more money, both of which then push the stock market even higher and continue the self-reinforcing bullish cycle.
"If stocks can hold [this] breakout for a couple of weeks or so, they often go on a multi-month long run fueled by the trifecta of buybacks, forced short-covering, and catch-up buying," Reynolds wrote Tuesday.
Of course, "If investors fight back and drive prices below the breakout area, then stocks often have to regroup for a month or two, sometimes with another panicky drop," he added.
Indeed, we've had many of those panicky sell-offs during this nearly eight-year bull market since the March 2009 financial-crisis bottom.
Another one after this Trump run would practically be welcomed by investors as a healthy correction. After all, the bigger the market "melt up," the bigger the typical meltdown.
