The Finance SPDR (XLF) has become the most boring of the nine sector SPDRs over the last five weeks. Boring today does not mean it will be boring tomorrow though. The chart below shows the Finance SPDR (XLF) surging to new highs in December, bouncing around in January-February and then moving into a narrowing range. The pink shaded area shows the Bollinger Bands in area format and the distance between the bands is the narrowest in years. We can quantify this by adding the BandWidth indicator, which is at its lowest level in years as well.
