Paychex Stock Slides 14% Over 9 Straight Down Days
A nine-day slide has erased billions in value.
Paychex (PAYX) stock has now moved lower for 9 consecutive trading days, a slide that has cut its price by 14%. That streak has erased about $6.1 billion from the company’s market value.
For anyone holding the stock, this is a sharp and painful move. Paychex stock trades at about $101.37 a share as of 9/25/2026. The sources for this article do not show why the move happened.
How The Streak Stacks Up Against The S&P 500
Here is how PAYX stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | PAYX | S&P 500 |
|---|---|---|
| 1D | -0.2% | 0.5% |
| 9D (Current Streak) | -14.5% | 1.6% |
| 1M (21D) | -18.8% | 0.9% |
| 3M (63D) | 2.5% | 5.3% |
| YTD 2026 | -6.6% | 13.1% |
| 2025 | -17.5% | 16.4% |
| 2024 | 21.3% | 23.3% |
| 2023 | 6.2% | 24.2% |
What do the numbers say about this slide?
Revenue over the last twelve months grew 14.0%, compared to a median of 7.3% for S&P 500 Industrials stocks. Its operating margin of 39.2% is also well above the 17.6% median for its peers.
Despite that growth and profitability, the stock trades at a price-to-earnings multiple of 20.0, which is below the median of 26.7 for its sector. The move is also specific to the stock; over the same 9 trading days, the S&P 500 returned +1.6%. While sustained, such streaks are not unique: 3 other S&P 500 stocks are currently on losing streaks of 9 days or more.
What does a streak like this actually tell you?
A long streak is information, not an instruction. It tells you that a stock has momentum and has captured the market’s attention, but it does not tell you whether that attention is justified or where the price will go next.
The disciplined response is to check the business against the price. The data here allows for a starting point: a profitable, growing business whose valuation multiple now sits below its peer-group median after a significant, company-specific slide.
If the drop has you weighing an entry, resist buying on price alone. Our Buy the Dip screen ranks the marked-down names where growth and cash generation still hold up.
Weakness In One Name Should Be Noise, Not News
For a diversified holder, a streak like this is a data point. For a concentrated one, it is a hole in the plan. The difference is never the stock; it is the portfolio built around it.
Building that portfolio is what the Trefis High Quality (HQ) Portfolio does: roughly 30 businesses with the cash generation and balance-sheet strength to absorb a bad month, selected and rebalanced by rules. It has a track record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000. Make the next streak, in either direction, someone else’s drama.
