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 | -1.5% | 0.4% |
| 9D (Current Streak) | -22.8% | 0.6% |
| 1M (21D) | -25.2% | 2.0% |
| 3M (63D) | -25.5% | 9.5% |
| YTD 2026 | 29.6% | 10.2% |
| 2025 | 388.1% | 16.4% |
| 2024 | 63.6% | 23.3% |
| 2023 | -43.2% | 24.2% |
The selling streak aligns with strained fundamentals.
While the company’s revenue grew 34.1% over the last twelve months, its operating margin is -31.9%, a stark contrast to the S&P 500 median of 18.4%. Similarly, PL trades at a price-to-earnings multiple of -23.7, while the median for the index is 24.2. This move appears to be the stock’s own story, not the market’s; over the same 9 trading days the S&P 500 returned +0.6%. Streaks themselves are not rare, with 33 S&P 500 stocks currently on losing streaks of 3 days or more.
A streak is a signal to re-evaluate, not a command to act.
A multi-day price move is information. It signals that the market’s attention is focused and that momentum has taken hold, but it is not an instruction to buy or sell. The disciplined response is to check the business against the price. The data on profitability and valuation relative to the broader market provides a clear starting point for that 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. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.
Falling Prices Test Conviction. Rules Do Not Flinch
