No rule matched.
Weaknesses

- Underperforming the U.S.A. 500 over the trailing 12 months.
- Low relative market share vs the industry leader (0.04x).
Opportunities
- Trades at a lower P/E than the industry average (13.3x vs 20.0x) despite a higher return on invested capital -- a possible re-rating opportunity.
- A meaningful share of tracked competitors (37.50 %) show financial-distress signals, a possible opening to gain share.
