Major markets around the globe sold off today with the pundits pointing to tonight's US presidential debate as the main source of market anxiety. Our benchmark S&P 500 plunged at the open and, after a puny bounce, sold off to a narrow mid-afternoon trading range.
The index closed with a 0.86% loss, a tad above its 0.91% intraday low moments before the close. Monday's loss essentially erased the no-rate-hike rally that began last Wednesday with the release of the September FOMC statement.
The yield on the 10-year note closed at 1.59%, down three basis points from the previous close.
