Data


World Credit Risk Factor, 1989 – 2009

From: The World Price of Credit Risk, Review of Asset Pricing Studies, 2012, Vol. 2 (2), pp. 112-152.

Description: The world credit risk factor is constructed as follows. Each month, countries are sorted into terciles based on their sovereign credit rating at the end of month t-1. In month t, the return for each tercile is calculated as the equally weighted average monthly return across all countries in the tercile. The world credit risk factor is defined as the return differential between high and low credit risk countries. The sample consists of 75 countries (24 developed and 51 emerging). Returns are U.S. dollar denominated.


Bond Momentum Profits (P10-P1 returns), 1974 – 2011

From: Momentum in Corporate Bond Returns, Review of Financial Studies, 2013, Vol. 26 (7), pp. 1649-1693.

Description: Each month t, bonds are sorted into decile portfolios, P1 to P10, based on their cumulative returns over months t-6 to t-1 (formation period). The momentum strategy is long the winner portfolio, P10, and short the loser portfolio, P1. These positions are held over a six-month holding period (t+1 through t+6, i.e., after a one-month lag). Portfolio returns are equally weighted across their constituent bonds. The overall strategy month-t portfolio return is the equally weighted average month-t return of strategies implemented in the prior month and strategies formed up to six months earlier. The data represent the monthly momentum strategy profits (P10-P1) during the holding period. Momentum strategy profits are provided for all bonds, investment grade bonds, and non-investment grade bonds (the rating classification is done at the end of the formation period). The bond data is obtained from five databases – Lehman, DataStream, Bloomberg,TRACE, and FISD. The final sample contains a total of 81,491 U.S. corporate bonds over the period from January 1973 to June 2011.
