The year's hot sectors, from the Barron's cover story, "Outlook 2018: The Bull Market's Next Act":

• "Financials, once again, are Wall Street's favorite stocks for the new year. The industry should be helped by higher interest rates, lower taxes, and an economy growing by nearly 3% a year."

• "Tech stocks led the market for most of this year with a gain of 35%, helped by an even more powerful rally in the so-called FANGs: Facebook, Amazon.com, Netflix, and Google, owned by Alphabet."
• "At 17.7 times next year's estimated earnings, tech valuations aren't cheap, but they're well below valuations in the dot-com era, and underlying earnings growth is strong."
