The company behind the wires

Beating the index everywhere

PWR is up 48.6% year to date and 67.9% over 52 weeks, against 11.6% and 17.3% for the S&P 500. Over three months it gained 9.4% versus 3.4%.

Shares sit 20.5% below their $788.75 high from May 6. The stock holds above its 200-day average, though an August slip under the 50-day hints at consolidation.
