Getty Images Trade tensions continue to dominate headlines.The threat of a full-blown U.S.-China trade war is having less impact on both investor sentiment and stock prices than might be expected, judging by double-digit gains for the Nasdaq and modest but positive returns for the S&P 500 so far this year. To a large degree, the prospect of a wider trade conflict hasn’t been enough to untrack the market leaders that lifted Wall Street throughout the first half of 2018 — albeit with higher volatility. Large-capitalization technology and internet stocks continue to hit new records. Meanwhile small-cap stocks, a group that is reliant on the domestic economy and is somewhat insulated from trade woes, rallied to all-time highs in the past week.via
