Volatility is here to stay in the markets, at least until we get a resolution on trade, says Kevin Nicholson. He sees the S&P 500 rangebound between 4900 and 5500, driven by day-to-day reactions to trade headlines. Nicholson expects the Fed to stay on hold for the rest of the year due to uncertainty around trade and inflation, which he believes is slowing down, not picking up steam.
