Stock futures Monday are slightly positive after OPEC+ signaled steady production cuts, bolstering oil-linked equity futures and reinforcing energy sector earnings projections. History doesn't repeat itself, but it often rhymes. And there's no denying the fact that the Shiller P/E ratio is inversely correlated with 10-year forward returns. As such, as the S&P 500 valuation continues to climb higher, the expected returns going forward become worse and worse. The firm upgraded global equities to overweight from neutral for the next three months, saying that "good earnings growth, Fed easing without a recession and global fiscal policy easing will continue to support equities." Stock futures Monday are edging higher following upbeat manufacturing PMI data from Europe, hinting at global growth resilience that could benefit U.S. exporters.
