As far as I know, the only investing books to mesh quantitative investing and value investing have been What Works on Wall Street, The Little Book That Still Beats the Market, and Ben Graham Was A Quant.
Quantitative Value shares a lot in common with What Works on Wall Street, and improves on The Little Book.
In fact, this was probably one of the best investing books I've ever read, combining the tried-and-true approach of value investing, behavioral finance, and quantitative methods to produce one very interesting piece.
I really, really, REALLY wanted to give this five stars, as it is exceptional, but there were several major issues with their methodology and logic. But first, the positives.
PROs:
- Explains basic cognitive biases typically affecting investing and how behavioral finance can help improve results by methodically sticking with the Quantitative Value program.
- Completely dissects Greenblatt's Magic Formula (From The Little Book That Still Beats the Market), demonstrating which of the two formulas has contributed more to the returns, how to possibly improve on the formula, and using it as a benchmark to which the authors compare their Quantitative Value approach.
- Tests a composite price metric of EBIT/EV, EBITDA/EV, E/P, B/P, Gross Profit/EV, and FCF/EV. Interestingly, the composite score doesn't outperform the best performing single metric (EBIT/EV), which is at odds with the composite score findings in "What Works on Wall Street," which consisted of P/S, P/E, P/B, EBITDA/EV, and P/FCF. Can draw your own conclusions, but I suspect the divergence is due to O'Shaughnessy included P/S and P/FCF, rather than FCF/EV (a flawed metric discussed below) and GP/EV.
- Uses Gross Profit to Assets [(Revenue - Cost of Goods Sold)/Total Assets] and Gross Profit to Enterprise Value, which are both metrics I've never seen tested before in the literature. GPA as a performance metric makes more sense than the traditional Return on Assets (more of this in a bit), and their test results show both produce solid returns.
- Compares using 10 year average earnings multiples to the typical last twelve month multiples, which is something I wish had been included in What Works on Wall Street.
- Goes into sufficient detail to detect earnings manipulation (using accruals) and financial strength and distress (Piotroski F-Score, Altman Z-Score, and Beneish M-Score are all discussed). This is particularly useful in deciding which stocks to exclude from a portfolio, as these are the ones most likely to hamper over-all returns.
- Keeps the discussion regarding CAPM and Beta to three or so pages. Beta has been discredited enough that it would be nice for it to be never mentioned again in the literature, but the authors limit it to a perfectly acceptable blurb.
