KEY POINTS
  • Stocks come off their worst week in two years, with some investors worried about what's ahead.
  • Stock futures were sharply lower in Sunday evening trading, but often futures markets look vastly different from the next day when stocks open.
  • Rising yields were a culprit behind the stock sell-off and could continue to rise, with plenty of Fed speakers and some major bond auctions in the week ahead.
  • Jerome Powell is sworn in as Fed chair on Monday.
