A trading rule measuring stock flows is about to trigger a sell signal

Despite major indices reaching new record highs, including the S&P 500 topping 6,700, market strategists are signaling increased risk for a pullback. Bank of America's Michael Hartnett noted that global equity and high-yield bond inflows are at 0.9% of AUM, nearing the 1.0% threshold for a contrarian sell signal, while the S&P 500's Relative Strength Index (RSI) is at 69, approaching overbought territory. Although some experts highlight strong fundamentals like double-digit earnings growth and reduced volatility, these technical and flow indicators suggest heightened caution is warranted for equities.

Analysis

Despite major U.S. indices achieving record highs, with the S&P 500 surpassing 6,700 and the Dow Jones Industrial Average closing above 46,519, market technicals and fund flow data are indicating a heightened risk of a pullback. According to Bank of America, inflows into global equities and high-yield bonds have reached 0.9% of assets under management over the past four weeks, placing the market just shy of a 1.0% contrarian sell signal. This signal would be triggered if global equity funds see inflows over $20 billion and high-yield bond funds exceed $1.5 billion in the coming week. Concurrently, the S&P 500's Relative Strength Index (RSI) has climbed to 69, bordering the 70 level that typically signifies overbought conditions. These cautionary signals contrast with robust underlying fundamentals, including double-digit earnings growth, strong free cash flow, and significant corporate stock buybacks, which some strategists believe will continue to support the market. Nevertheless, the combination of euphoric fund flows and stretched technical indicators suggests investor sentiment may be overly optimistic, increasing vulnerability to a near-term correction even as cross-asset volatility remains low.

Key Decisions for Investors

• Investors should closely monitor weekly fund flow data, as inflows exceeding $20 billion into equities and $1.5 billion into high-yield bonds would trigger a key contrarian sell signal.
• Given the S&P 500's RSI is approaching the 70 overbought threshold, it may be prudent to consider trimming profits on highly extended positions or implementing hedging strategies to mitigate downside risk from a potential market pullback.
• While strong corporate fundamentals like double-digit earnings growth and buybacks provide a supportive backdrop, the divergence with technical and flow indicators warrants caution; maintain exposure to quality names but be prepared for an increase in volatility.
• Evaluate exposure to high-yield bonds, as aggressive inflows into this asset class are a specific component of the noted sell signal, suggesting the credit market may also be susceptible to a reversal.
