Wall Street sentiment creeps toward 'sell' as risk appetite builds, says BofA

Wall Street's sentiment is shifting towards a 'sell' signal as Bank of America's Sell Side Indicator (SSI) approaches a contrarian sell threshold, currently at 55.7%. Despite a 2% gain in the S&P 500, concerns over valuations and rising speculative activity, including meme stocks, are noted. BofA favors large-cap value stocks as a hedge against potential market corrections, indicating that while optimism is growing, it hasn't reached extreme levels yet.
