Franklin Templeton put together a great report on value stocks underperforming growth stocks since the financial crisis. It's exciting because it suggests that value stocks are poised to outperform in the near future.
"Value has underperformed growth for the longest period on record and as of August-end was trading at the widest valuation discount to growth since the Dotcom Bubble of the late 1990s. This is unusual, as value investing as a style has historically outperformed growth more often than not. As major global central banks contemplate policy normalization over our long-term investment horizon, we see a strong case for a potential recovery in value from currently depressed levels."
