Another week, another risk-on rally. US stocks continued to be a leader this week in global markets. SPDR S&P 500 (SPY) surged 3.3% at the close of the trading week (Aug. 28), marking the fund’s fifth straight weekly advance. Bonds, however, hit a rough patch. Vanguard Total US Bond Market (BND) fell 0.6% this week – the second weekly loss in the past three.
