PL Versus The S&P 500, Streak And Beyond
Here is how PL stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | PL | S&P 500 |
|---|---|---|
| 1D | -11.3% | -0.5% |
| 11D (Current Streak) | -33.3% | 0.5% |
| 1M (21D) | -27.8% | -0.3% |
| 3M (63D) | -35.8% | 7.3% |
| YTD 2026 | 12.0% | 10.1% |
| 2025 | 388.1% | 16.4% |
| 2024 | 63.6% | 23.3% |
| 2023 | -43.2% | 24.2% |
The selling streak aligns with strained fundamentals.
While revenue over the last twelve months grew 34.1%, well ahead of the S&P 500 median of 7.5%, profitability metrics show significant pressure. The company’s operating margin is -31.9%, compared to an S&P 500 median of 18.4%. Similarly, PL trades at a price-to-earnings multiple of -20.5, against the median of 24.5.
This move appears specific to the company, not the broader market, as the S&P 500 returned +0.5% over the same 11 trading days. For context on market momentum, 53 S&P 500 stocks are on winning streaks of three days or more, while 18 are on losing streaks.
A streak is a signal to re-evaluate, not a command to act.
An extended move in a stock is information. It tells you that momentum and attention are focused on a name, for better or worse. It is not, by itself, an instruction to buy or sell.
The disciplined response is to use the streak as a trigger to check the business against the price. The market appears to be weighing the company’s lack of profitability against its growth, and the data here provides a starting point for your own assessment.
If the drop has you weighing an entry, resist buying a falling price alone. Our Buy the Dip screen ranks the marked-down names where growth and cash generation still support a recovery.
Those watching the group rather than this one name have another route: our ETF Scorecard shows how the U.S. industrials funds stack up. That way, no single company’s next surprise decides the outcome.
PL Has Fallen 86% From A Peak Before As Well
A stock that falls day after day is a live lesson in what single-name exposure feels like. PL itself has fallen 86% from a peak within the past five years, and a fall like that lands very differently when one position carries too much of your wealth. Knowing what a repeat would do to your net worth is exactly what the Trefis Wealth team computes, with the same rules-based systematic discipline that runs our High Quality Portfolio.
