1/ Mapping Investable Return Sources to Macro Environments (AQR)
"Style premia have less macro exposure than do asset classes. Additionally, a diversified portfolio (for asset classes and style premia) may rely less on a specific macroeconomic outcome."
2/ "We must stress the limitations of this type of analysis. Any empirical result is specific to the sample period (here 1972-2013) and dependent on design choices.
"Long/short returns are scaled to target 10% annual volatility. We subtract no trading costs or fees."
3/ "The weak relation between equities & growth reflects the forward-looking nature of equity returns. The correlation between annual equity returns & our contemporaneous (*next* year's) growth indicator is 0.24 (0.50).
"Styles were positive in both up and down
environments."
4/ "The distinction between simple & partial correlations is the same as that between slope coefficients in simple & multiple regressions.
"It is difficult to find an asset class or even a style that performs well in a stagflationary (growth-down, inflation-up) environment."
5/ "Again, results might be specific to this sample or our specifications of style premia and macro environments.
"Even L/S styles can be more market-directional in certain asset classes (e.g. currency carry) than in the broadly diversified style composites we analyze here."
6/ "It is difficult to populate the upper-left quadrant on the risk graphs, with rising real yields, inflation, volatility and illiquidity all posing a challenging environment – all compounded by negative growth.
"Style premia tend to be closer to the origin in all four graphs."
7/ "The relationships we document are not predictive and thus less useful for tactical decisions than strategic ones.
"As post-WWII history is characterized by broadly benign growth and inflation, investors may have grown to consider equity-friendly conditions too complacently."
1/ Moneyball: The Art of Winning an Unfair Game (Michael Lewis)
"Baseball was at the center of a story about the possibilities—and limits—of reason. It showed how an unscientific culture responds (or fails to respond) to the scientific method." (p. xiv)
2/ "A small group of undervalued professional players & executives, many of whom had been rejected as unfit for the big leagues, turned themselves into one of the most successful franchises.
"How did one of the poorest teams, the Oakland Athletics, win so many games?" (p. xi)
3/ "Hitting statistics were abundant & had, for James, the powers of language. They were, in his Teutonic coinage, 'imagenumbers.' Literary material. When you read them, they called to mind pictures. He wrote... 'To get 191 hits in a season demands (or seems to) a consistency...
3/ "Value, momentum & defensive/quality applied to US individual stocks has a t-stat of 10.8. Data mining would take nearly a trillion random trials to find this.
"Applying those factors (+carry) across markets and asset classes gets a t-stat of >14."
2/ "The model's four terms describe different life stages for an individual who marries during the sample period. The intercept reflects the average life satisfaction of individuals in the baseline period [all noncohabiting years that are at least one year before marriage]."
3/ " 'How satisfied are you with your life, all things considered?' Responses are ranked on a scale from 0 (completely dissatisfied) to 10 (completely satisfied).
"We center life satisfaction scores around the annual mean of each population subsample in the original population."
1/ Short-sightedness, rates moves and a potential boost for value (Hanauer, Baltussen, Blitz, Schneider)
…
* Value spread remains wide
* Relationship between value and rates is not structural
* Extrapolative growth forecasts drive the value premium

2/ "The valuation gap between cheap and expensive stocks remains extremely wide. This signals the potential for attractive returns going forward."
3/ "We observe a robust negative relationship between value returns and changes in the value spread.
"The intercept of ≈10% can be interpreted as a cleaner estimate of the value premium, given that it is purged of the time-varying effects of multiple expansions & compressions."
