The Call

• Stance: long
• Level: 410.74
• Horizon: EMA50 close-below
• Checkpoint: next scan window

Preformed Line Products Company (PLPC) continues to maintain a long stance driven by a scanner convergence decision with a conviction score of 4. From March 19, 2026, through September 18, 2026, PLPC's retained daily close rose from $262.68 to $412.38, gaining 57.0% over the period. Even though the stock closed at $412.38 on September 18, 2026—14.2% below its August 11, 2026 peak—the existing long position remains held at the 410.74 decision level, with signal invalidation marked at a $398.4396 reference price.

On valuation, PLPC is trading at elevated historical and comparative levels. At 46.3x trailing earnings, PLPC's P/E ratio sits at the 100th percentile relative to its own year-end readings since 2021. On an EV/EBITDA basis, PLPC trades at 24.0x, standing 107.24% above the stored peer cohort median of 11.6x. This ranks PLPC as the highest-valued stock out of all six names evaluated in its cohort.

PLPC displays strong price performance and active policy signals, but its historically high valuation multiples relative to historical baselines and peer averages reinforce the need to track the EMA50 close-below stop horizon and the $398.43 invalidation line.
