While the EPS beat rate this earnings season has been strong, there's another data point that has been even more eye-popping. While the earnings per share numbers grab the headlines, it's what companies say about their future quarters that impacts stock prices the most on their report days. As shown below, 20.3% of US companies have raised guidance so far this earnings season. The highest reading for this number has barely broken 15% in any prior quarter this decade. And if we compare the percentage of companies raising guidance versus the percentage of companies lowering guidance, no other quarters come even close to this one. It will be hard to keep this up as earnings season progresses, but it's also shaping up to be a record-breaking quarter on the positive side.
