Last Friday’s bond driven sell-off was a bigger event for quant flows than Brexit according to Bank of America.
Since Brexit, financial markets around the world have enjoyed a period of extended stability. Even though markets were rocked following the June 24 vote, central bank rhetoric in the weeks following calmed nerves, sent bond yields plunging and pushed investors into equities in the hunt for yield. Through Thursday September 8, the S&P 500 recorded its longest stretch in history of trading within a range of 1.77%. The data goes back to 1928. However, on Friday the lull was broken as the S&P 500 fell 2.45% and similar losses could be seen today.
