Value stocks, those with stable fundamentals and subpar valuations, haven't been this cheap since the financial crisis, according to Bank of America.
Cheap equities enjoyed a resurgence in September from a decade of underperformance as investors bet on economically sensitive, underpriced stocks on hopes for a U.S.-China trade deal. Value names have become particularly inexpensive relative to momentum stocks, creating a buying opportunity, the bank said.
"Value has never been this cheap vs. Momentum," Savita Subramanian, head of U.S. equity and quantitative strategy at Bank of America Merrill Lynch, said in a note Friday. "Many signals indicate that the recent rotation into Value/out of Momentum could continue."
The only time in history that value stocks have gotten this cheap was in 2003 and 2008, when the group outperformed momentum stocks by 22 and 69 percentage points, respectively, over the subsequent 12 months, according to Bank of America.
One of the biggest exchange-traded funds focused on the value factor is the iShares Edge MSCI USA Value Factor ETF, which has gained 20% this year, slightly lagging the S&P 500's 23% return. But it has recently outperformed the iShares Edge MSCI USA Momentum Factor ETF, which is up about 19% this year.
Stocks have rallied to records over the past couple of weeks on optimism about trade and better-than-expected economic data. A gauge for U.S. services activities topped expectations for October, while the labor market remains solid as job creation easily beat estimates last month.
"Some recent signs of stabilization in macro data also supports that the downturn might be bottoming and the Value rotation could continue," Subramanian said.
Bank of America said the health-care sector notched the top spot in its quantitative analysis on the back of strong earnings. The bank has a year-end target for the S&P 500 of 2,950, which is below Thursday's record close of 3,085.18.
"The 'Downturn' phase in our US Regime Indicator has historically lasted eight months on average (we're now in month eight)," Subramanian said. "The next phase is 'Early Cycle,' when Value typically outperforms."
AQR Capital founder Cliff Asness, a long-time hedge fund skeptic, gave value stocks a rare stamp of approval, saying investors should increase their allocation toward the group.
