The Streak Next To The S&P 500
Here is how LAZ stock stacks up against the S&P 500 over the streak and the periods around it:
| Return Period | LAZ | S&P 500 |
|---|---|---|
| 1D | -0.9% | 0.2% |
| 9D (Current Streak) | -20.6% | -0.9% |
| 1M (21D) | -20.9% | -0.7% |
| 3M (63D) | -18.3% | 2.0% |
| YTD 2026 | -24.0% | 11.8% |

| 2024 | 23.3% | |
| 2023 | 24.2% |
Is this move about the market or the stock?
The data suggests this is the stock’s own story. Over the same 9 trading days, the S&P 500 returned -0.9%. The sources for this note do not show why the move happened. The company’s fundamentals look weak against medians for S&P 500 Financials stocks. Lazard’s price-to-earnings multiple is 16.0, above a median of 14.0.
At the same time, its other metrics trail. Revenue over the last twelve months grew 6.3%, below the 10.2% median. Its operating margin of 11.1% is also below the median of 26.9% for its S&P 500 sector peers.
A streak is information, not an instruction.
A long streak, in either direction, tells you that a stock has sustained momentum and captured the market’s attention. It does not, by itself, tell you whether the new price is justified, too high, or too low. The disciplined response is to treat the streak as a prompt to check the business against its valuation. The numbers here offer a starting point for that work.
A slide like this poses an obvious follow-up: which marked-down stocks are actually worth buying? Our Buy the Dip screen runs that test every day, flagging beaten-down names whose fundamentals still hold up.
And for anyone who would rather back the theme than one company’s story, a financials ETF like XLF holds the whole group, not the single stock. It is still a concentrated bet on that one theme, though, which is exactly the gap the portfolio below closes.
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 re-balanced 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.
