S&P 500 will post negative returns in 2018 - Gundlach

Comments from DoubleLine Capital Chief Executive Jeffrey Gundlach, also known as "Bond King", are crossing the wires via Reuters-

• The S&P500 may go up 15 percent in the first part of the year, but I believe, when it falls, it will wipe out the entire gain of the first part of the year with a negative sign in front of it. 
• If the 10-year goes above 2.63... it will accelerate higher and equity markets are going to be spooked and maybe that's the cocktail that is coming our way. 
• Financial markets have not priced-in a "more hawkish" ECB, maybe that's why the euro has started to rally... maybe it will rally further.
