Weekly Factor Returns
Factor returns were mostly linear across the capitalization spectrum, with the largest spreads in the small cap universe, followed by mid cap spreads, and the smallest among large caps. Medium-term momentum (MTM) was the lone factor that did not follow that exact pattern. All factor returns were positive and within normal ranges.
