Lazard Stock Slides 20% Over 8 Straight Down Days
An eight-day slide has erased a significant portion of the company’s value, presenting a mixed picture when set against its fundamentals.

For anyone holding the stock, the move has pushed its price to about $36.06 a share as of 9/17/2026. The sources for this note do not show a specific reason for the sustained selling.
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 | -1.5% | 1.1% |
| 8D (Current Streak) | -19.9% | -1.0% |
| 1M (21D) | -18.2% | -0.7% |

What does the data behind this streak show?
The move appears to be specific to the stock. Over the same 8 trading days, the S&P 500 returned -1.0%, a much smaller decline. The company’s fundamentals present a mixed case when compared to medians for S&P 500 Financials stocks. Lazard’s revenue over the last twelve months grew 6.3%, below the 10.2% median for its peers. Its operating margin of 11.1% is also below the group’s 26.9% median.
Despite this, the stock trades at a price-to-earnings multiple of 16.1, which is above the peer median of 14.0.
A streak is information, not an instruction.
A move of this length and size is a clear signal about momentum and market attention. It is not, by itself, a reason to act. The disciplined response is to treat the streak as a prompt to check the underlying business against its new, lower price.
The numbers show a company trading at a valuation premium to its peers, even as its recent growth and margin figures trail them. That is the core tension a potential investor must resolve.
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 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.
