The Dow DJIA, +0.51% 24,000 ink barely had a chance dry on what’s left of the business pages on Friday, when one renowned bull, who’s actually had his finger on the pulse of the market lately, already started calling for the next big round number.

Wharton’s Jeremy Siegel, in our call of the day, told CNBC following last week’s milestone that the blue chips are poised to take out 25,000 in a matter of days, thanks mainly to the passage of Trump’s tax reform package.

“The corporate tax cut is particularly what I think the market wants,” he said. “That could boost earnings by 8% or so, and that’s a positive for stocks.”

But the current pace of gains won’t last, Siegel warned, setting his expectations for returns in single digits next year. Nothing alarming about that, of course, though it’s not exactly what investors have grown accustomed to lately.

“We’re moving up to full valuation,” Siegel said. “It doesn’t mean there’s going to be a break in the market, a bear market or anything like that. But what are you up — 15 to 20% or more this year? That’ll be harder to come by in the future.”

Beyond the full valuations, Seigel said political uncertainty and the Fed’s monetary policy could wake up slumbering volatility into 2018.

Watch the full interview:

In addition to the tax-plan boost, there’s some seasonality that could come into play this month. December is traditionally a most wonderful time of the year for stocks, with the Dow gaining 74% of the time over the past 100 years and averaging a monthly return of 1.6%, according to Bespoke Investment Group.

The way things are looking in the perky market this morning, Siegel’s call is certainly on track.

The chart

The Financial Times posted this chart on Instagram over the weekend to compare the mania we’re seeing in bitcoin to a mania of years past.

“Is bitcoin a new-age precious metal?” the FT asks.

As you can see, the 1980 peak for silver and last week’s high in bitcoin are rebased to 100, and the results show a “startlingly similar” ascent.

“Bitcoin is indeed behaving a lot like a precious metal at a time of pessimism, where something odd is happening to constrict supply,” the FT said. “Silver’s collapse over the following year was total.”
