Yes, we know. The new year is here. It's never too late to get your investments in order. Billionaire Ken Fisher stopped by 14 Wall Street and shared some advice on how to prepare your portfolio in 2018.

First up, remain overweight foreign stocks vs. U.S. stocks. 

He suggests a portfolio with material exposure to U.S. stocks, but well under 50%.

Meanwhile, the S&P 500 is up almost 20% this year and that's in-line with what's traditionally seen in a bull market, according to Fisher, who is Chairman of Fisher Investments. 

"This year in the U.S. stock market is the average annual return of a bull market in history," Fisher said in an interview with TheStreet. "It's not an above average year - people forget that."
