The yield curve inverted Friday triggering fears of a recession and a 1.9% drop in the Standard & Poor's 500 — the second-worst one-day drop this year. Then, Robert Mueller's Special Counsel delivered his report.

The index of U.S. leading economic indicators — a forward looking composite of 10 indexes of American economic growth — increased 0.2% in February to 111.5, following no change in January, and a 0.1% decline in December.
