[Quantitative Model Shows U.S. Stock Rally Approaching 'Frenzy' Zone] According to Golden Finance, on May 8, the U.S. stock market experienced a historic surge, reaching new highs. However, signs of overheated sentiment suggest that this rally may be entering a slowdown phase. The rebound since the March lows has been partly driven by expectations of eased U.S.-Iran tensions and significant corporate earnings growth, which have pushed investor sentiment close to the 'frenzy' zone indicated by Bloomberg Industry Research strategists' quantitative model. This model tracks six indicators, three of which have driven sentiment to this level: high-yield corporate bond spreads, low volatility, and pairwise correlation.
