Wall Street was growing more bullish in the final weeks before the Nov. 5 presidential election — a contrarian sign that may suggest limited upside for U.S. stocks, according to BofA Global Research.

BofA’s Sell Side Indicator (SSI), which tracks Wall Street strategists’ average recommended equity allocations, in October climbed to its highest level in more than 2? years (see chart below). The sentiment gauge rose 50 basis points to 56.7% last month, resuming its climb after pausing in September, a team of BofA strategists led by Savita Subramanian, head of U.S. equity and quantitative strategy, said in a Friday client note.

But that may not actually be a good thing for stocks. The BofA team has long touted the SSI as “a reliable contrarian indicator” since an overly bullish sentiment may cause some investors to take an opposite view — when everyone else in the stock market is optimistic, it is often a good time to sell.

Despite the bullish tilt in October, the SSI remained in “neutral” territory — but it was just 1.4 percentage points shy of a contrarian “sell” signal, Subramanian and her team said.

“Its current level of 56.7% suggests a price return of 11% for the S&P 500 SPX over the next 12 months, much lower than recent history, but still roughly in line with the market’s annualized return over the past decade,” the BofA strategists wrote.

However, investors may want to seize this opportunity to “stay selective” and focus on “more unloved” areas of the market, such as high-dividend-yielding stocks, large-cap value stocks and cyclicals, Subramanian and her team said.

To be sure, the heightened stock-market sentiment coincided with a challenging month for the market, as investors prepared for a hectic stretch with new economic data, third-quarter corporate earnings, the Federal Reserve’s policy meeting and the election. The S&P 500 and the Dow Jones Industrial Average DJIA in October suffered their worst month since April, while the tech-heavy Nasdaq Composite COMP posted its biggest monthly decline since July, according to Dow Jones Market Data.
