CSX Corporation's management tone tended to become more positive when quarterly net income improved. This relationship remained statistically notable after the multiple-testing adjustment.
The analysis measures a same-filing relationship, not a forecast. Limitations
Each dot represents one 10-Q filing. Points farther right have more positive MD&A tone. Points higher on the chart had stronger year-over-year net income growth, after extreme percent changes are capped. Upper-right and lower-left points indicate tone and earnings moving in the same direction. How to read this chart
