Skew Strategy with a Sliding Scale [John Orford]
Check out the previous post in this blog for a blow by blow account of building strategy around skewness (part 1). Up until now the strategy knowed back and forth between buying and selling 100% as the skew became more or less favourable. Now, we add a little nuance. The implied skew index is a

Bond/Utility Divergence a Warning Sign...for the S&P 500? [Dana Lyons]
Given their relatively high yields, utility stocks have long been thought of as proxies, or at least competition, for bonds. And while that relationship is often overplayed (utility stocks are first and foremost, stocks), there is some credence to the notion. Since 1970, there is a 26% positive
