SPY outperforming TLT

From the chart I published here on October 14th (tradingview.com/v/gmom0rWu/) highlighting the historical rhythm of the SPY and TLT and how the markets were positioned to move from TLT back to SPY, the SPY rallied 8% in the following 2 weeks while the TLT fell 5% for a net performance gain of 13%. Since the end of October, that performance disappeared, and is now building again to a 4% spread.
