Around the time she was forced out, HP was doing worse than both IBM and Dell. Immediately after she left however, HP began rising, and wound up outperforming both IBM and Dell. In fact, after Carly left, HP was the most improved company on your chart... AFTER Fiorina.

BTW, I run two LLCs, so I'm not one of those you're tired of.
The counter argument would be that she laid the ground work for future success, she made the correct decisions during a transition period and future success was due to her foresight.
“Immediately after she left however, HP began rising,..”
No. Based on this chart, HP was coming back up BEFORE she left. Don’t cherry pick to support your view, like East Anglia.
