Nasdaq’s Rebound After a 5.5% Drop Has Not Restored Pre-Selloff Levels

On November 5, 2026, the Nasdaq Composite fell 5.52% to 24,315 and closed more than 10% below its October 6 record, the usual line for a correction. The S&P 500 fell 4.36%. Reuters described the session as the Nasdaq’s deepest one-day drop in 19 months, led by chip and AI-linked shares after Democrats won control of Congress and markets priced a risk of slower data-center construction and tighter rules on artificial intelligence.

What followed was a rebound that felt larger than the repair it delivered. On November 6 the Composite rose 1.09% to about 24,579, recovering less than a fifth of the prior session’s point loss, and still finished the week down about 3.4%. On November 9 it rose about 2.7% to 25,253, while the Nasdaq-100 rose about 3.4% and the QQQ ETF about 3.5% — close to the roughly 3.7% “roaring” bounce described the next morning in a ZeroHedge commentary by QTR’s Fringe Finance. Even after that stronger day, the Composite remained below its November 4 close near 25,737. By November 11, Reuters reported that early indicators suggested it was too soon to sound the all-clear. Mark Newton, head of technical strategy at Fundstrat, told Reuters: “You can’t have a 5% down day and close on the lows and then think the lows are in.” He said the rebound in the Nasdaq-100 ETF had stalled just below its late-October downtrend, and that near-term trends still pointed to more volatility. That is documented price action and documented professional caution. It is not, by itself, evidence that a bear market has started.

The commentary’s claim is narrower than a crash call, and it is mostly about arithmetic and attention. A 5.5% decline followed by a 3.7% rally leaves an index about 2% lower: 0.945 times 1.037 is 0.980. The green day can dominate the screen while the two-day result is still a loss. Repeat that two-day pattern on the order of thirty times — roughly a quarter of a trading year — and the same multiplication cuts an index nearly in half. Documented: the multiplication, which the author labels a hypothetical, not a forecast. Claimed: that investors systematically mistake the feel of the up day for evidence the trend has turned, because recency bias overweights whatever just printed. Speculated: that the present market will actually follow anything like that repeating path. The author says it will not.

The pattern has a name and a record that long predates this week. A dead-cat bounce — the phrase traced in the financial press to a December 1985 Financial Times description of a failed rebound in the Singapore and Malaysian markets — is a short rally inside a larger decline. Britannica notes that short covering, bargain-hunting, and ordinary trading biases can produce the spike without any improvement in the conditions that caused the drop, and that the pattern implies further decline after the rally fades. A related fact cuts against reading any large green day as confirmation that the worst is over. MarketWatch columnist Mark Hulbert, using Ned Davis Research bear-market dates, calculated that big up days occur more often inside bear markets than a random split of trading days would predict. Of Nasdaq-100 sessions that rose at least 10%, about 90% fell during bear markets, against a base rate of about 16% of all sessions occurring in those bears. Even at a 3% rally threshold, the bear-market share was about three times the base rate. Hulbert’s 2024 point was not about this November. It was that the size of a one-day rally is weak evidence a decline is finished.

History after corrections is mixed in a way that makes the seduction rational. CNBC’s review of Nasdaq correction entries over the prior decade found further rough selling in the following month in 2018, 2020, 2022, and 2025, then a return to rally mode within six months in every case except 2022. Average gains from correction lows were positive over three and six months. Both statements can be true at once: bounces are common, and some of them fail. The short-term reversal literature has long measured a bounce after extreme declines without treating it as a bottom. The useful distinction is not “rallies are fake.” It is that a pop after a crash is the ordinary shape of stressed markets, produced by shorts buying back and by buyers anchoring to last month’s price.

The behavioral half of the claim is also documented outside this episode. Recency bias — overweighting recent events relative to the longer record — is a standard result in behavioral finance, related to the availability heuristic described by Amos Tversky and Daniel Kahneman. Investopedia and Morningstar both describe how it pushes people to treat the latest tape as the new regime: chase what just worked, or assume the latest scare will continue in a straight line. Applied here, the claim is that a 3% up day becomes the story and the 5% down day becomes yesterday’s problem within a session. That is a claim about attention. It fits the documented bias. It is not, on its own, evidence that this particular bounce will fail.

The other side of the tape is why the bounce is seductive, and it is equally on the record. Deutsche Bank strategist Parag Thatte, cited by Reuters, described the selloff as a forced positioning unwind that pushed tech positioning below its April 2025 lows — levels from which the sector has previously bounced — and said the bank remained overweight. Keith Lerner of Truist told Reuters the firm was still giving technology the benefit of the doubt and still saw AI as the dominant theme of the bull market. Averages compiled after prior Nasdaq corrections show positive returns over the following year more often than not. A bounce can be the start of a repair. The rebounds of March 2020 were not dead cats. Telling those apart from the failed rallies inside the 2000–2002 decline, or from 2022’s summer rally that gave back its gains, requires information a single session does not contain: whether selling has exhausted, whether the policy or earnings reason for the drop has changed, and whether the rebound is broad or a reflex in the same names that led the fall.

What is documented this week is a real entry into correction, a real but incomplete rebound, and a split among named strategists about whether the low is in. What is claimed, by a heterodox finance newsletter and by a much older line of market practice, is that the emotional force of the up day systematically exceeds its informational content. What is speculated is that repeated incomplete recoveries are the path from here, or that the AI-infrastructure boom has already broken. A market can stage spectacular rallies and still stand lower than it did before the scare. Until breadth, positioning, and the policy facts move together, the size of the bounce remains a weak signal. That is not a reason to assume the worst. It is a reason not to treat one green close as the all-clear.
