About This Strategy

The Cornerstone Value Strategy is grounded in the principles of value investing, aiming to identify undervalued stocks that have the potential for long-term outperformance.


This strategy often involves buying stocks of companies with solid fundamentals but temporarily depressed prices, allowing investors to acquire assets at a discount. Additionally, O'Shaughnessy's approach advocates for patience and discipline, as value investing typically entails holding positions for extended periods to capture the full benefit of value realization.


O'Shaughnessy's methodology emphasizes key metrics such as price-to-book ratio, price-to-earnings ratio, and dividend yield to gauge a stock's intrinsic worth relative to its market price.


The Improved Cornerstone Value Strategy uses shareholder yield instead of dividend yield, which are the cash dividends paid out to shareholders. It also takes into account stock buybacks because reducing the amount of outstanding shares increases the value per share.
