Does not remain notable after adjusting for hundreds of tests. Why?
The analysis measures a same-filing relationship, not a forecast. Limitations

Upper-right and lower-left points indicate tone and earnings moving in the same direction. How to read this chart
Tone and earnings moved in the same direction in 8 of 15 comparable quarters.
