The futures traded lower this Friday morning following Thursday’s huge run for the stock market. Encouraging news on the trade front, which indicated that the United States and China will be renewing trade talks later this month, was the fuse that lit the market for some of the biggest gains of this year. But the trend of buying the dips has not worked as well lately as it did in prior years, and many investors have considered how they want their investments positioned for the longer term.
