Michael Santoli argues that the AI trade rebound is approaching a decisive test. In his CNBC Market Memo column of October 27, 2026, the senior markets commentator says the market may be nearing a “now-or-never” moment for artificial intelligence stocks to recover — not because the technology story has been proved wrong, but because positioning, sentiment, and the calendar are converging.
This is opinion and market commentary, not a forecast that a rebound is certain. Santoli’s case is that the conditions for a bounce are unusually clear, while the evidence that would confirm one has not yet arrived. The distinction matters: the article below reports and explains his argument, and identifies what would have to happen next for the argument to hold.
The Market Memo column frames the moment as a washout followed by a choice. After a sharp pullback in leading AI names, traders had sold aggressively, valuations had compressed, and expectations had fallen. Santoli’s point is that such a setup can produce a powerful rebound — but only if earnings, guidance, and spending plans give buyers a reason to return.
The Short Version: The AI Trade Rebound Case in Brief
- The claim: Santoli says the AI trade is nearing a now-or-never moment to rebound, after a washout in positioning and sentiment.
- The setup: Heavy selling, crowded exits, and reduced exposure created room for a sharp reversal if buyers re-engage.
- The catch: A rebound still needs confirmation from earnings, capital-spending plans, and customer demand — positioning alone is not enough.
- The test ahead: Results and guidance from the largest AI spenders and suppliers will show whether the pullback was a pause or a reassessment.
- The risk: If earnings disappoint, the same crowded positioning can unwind further, and the “now-or-never” window can close without a recovery.
- The status: This is an argument about market structure and timing, attributed to Santoli, not a verified outcome or investment advice.
THE CASE, AND THE CATCH
| What Santoli sees A washout in AI positioning after aggressive selling, creating the conditions for a rebound if buyers return. |
What must still happen Earnings and spending plans must confirm demand. Without that confirmation, the setup remains a possibility, not a recovery. |
The AI Trade Rebound Evidence Santoli Cites
Santoli’s column does not argue that artificial intelligence has stopped mattering. It argues that the trade — the crowded bet on a small group of leaders — had become vulnerable, and that the vulnerability has now been exposed. The evidence he points to is about behaviour, not about the technology itself.
1. Trader Exhaustion After a Crowded Sell-Off
The first part of the case is exhaustion. When a trade has been popular for a long time, selling can feed on itself: funds reduce exposure, momentum turns, and short-term traders pile into the same exit. Santoli’s framing suggests that process had run unusually far, leaving fewer forced sellers remaining. That does not guarantee buyers will appear, but it changes the balance of who is left to sell.
The column cites market strategists who track positioning and flows, including analysis that selling in leading technology names had become intense. The implication is that the market had moved from orderly profit-taking toward capitulation in parts of the AI complex — the kind of move that often precedes, but does not ensure, a counter-move.
2. Retail Dip-Buying Has Not Disappeared
A second strand of evidence is the persistence of retail buying. Santoli notes that individual investors continued to buy dips in familiar names even as professional positioning turned cautious. That behaviour is sometimes read as a contrary signal, and sometimes as a sign that belief in the theme remains broad. Santoli treats it as part of the setup rather than as proof: dip-buying can cushion a fall, but it cannot by itself reverse a reassessment by large spenders.
Together, these strands form a timing argument. The market, in Santoli’s telling, has cleared out weak hands and lowered the bar for a positive surprise. The question is whether companies will clear that lower bar.
THE DATA POINTS, ATTRIBUTED
| Positioning washout Attributed to Santoli’s reading of market positioning and strategist commentary cited in the column. |
Retail dip-buying Attributed to trading data discussed in the column, including retail flow observations. |
| Earnings test ahead Attributed to Santoli: results and guidance from major AI spenders are the next confirmation point. |
No rebound confirmed No rebound is reported as having occurred. The column argues a rebound is possible, not that it has happened. |
Why You Should Care: What an AI Trade Rebound Would Need
For readers who hold broad index funds, the AI trade matters because a handful of companies now carry outsized weight in the S&P 500. A rebound in those names can lift the whole index; a further slide can drag it down even if most other stocks are steady. That is why Santoli’s timing argument has implications beyond technology specialists.
Three tests will matter most in the coming reports. First, capital spending: are the largest buyers of AI infrastructure still planning to spend at the pace they promised? Second, monetisation: are customers paying enough for AI products to justify that spending? Third, guidance: are executives describing demand as broadening, or as concentrated in a few large deals?
If those answers are reassuring, the washout Santoli describes could become the base for a rebound. If they are cautious, the same positioning evidence could instead mark the start of a longer period in which investors demand more proof before paying high valuations. Either way, the column’s value is in naming the test, not in pre-judging its result.
Confirmed vs Reported vs Unknown: AI Trade Rebound
Because this article explains an opinion column, it is important to separate what Santoli argues from what has been verified independently.
STATUS OF THE CLAIMS
| Confirmed Santoli published a Market Memo column on October 27, 2026, arguing the AI trade is nearing a now-or-never moment to rebound. |
Reported / attributed Positioning had washed out and retail investors were buying dips, as described and attributed in the column. |
| Unknown Whether a rebound will occur, and whether earnings will confirm the setup, remains unknown at the time of writing. |
Not claimed No claim is made here that any rebound has happened, or that any stock should be bought or sold. |
Quick Answers: AI Trade Rebound Questions
What does Santoli mean by “now-or-never” for the AI trade?
He means the setup for a rebound — washed-out positioning and lowered expectations — is in place now, but it will not wait indefinitely. If earnings do not confirm demand soon, the opportunity for a sharp recovery may pass, and investors may reassess valuations instead.
Does a washout guarantee a rebound?
No. A washout means many sellers may already have sold, which can make a bounce easier, but a rebound still requires buyers with a reason to return. Earnings, spending plans, and guidance are the reasons Santoli points to.
Why does the S&P 500 matter here?
Because the largest AI-related companies carry significant weight in the index, their performance can move the broader market. A rebound or further slide in those names therefore affects many investors who do not own individual technology stocks.
Is this article investment advice?
No. This article reports and explains Santoli’s opinion and market commentary. It does not recommend buying or selling any security, and readers should consider their own circumstances and seek professional advice where appropriate.
The Takeaway: AI Trade Rebound as Argument, Not Outcome
Santoli’s column is best read as a challenge to the market, not as a prediction that has already come true. The AI trade rebound he describes is possible because positioning has washed out; it is not yet real because the earnings evidence has not arrived. That gap — between setup and confirmation — is the whole story.
Watch the next round of results and guidance from the companies spending most heavily on AI. If they confirm demand, Santoli’s now-or-never framing will look prescient. If they do not, the washout may simply have been the first stage of a longer repricing. Either outcome will be clearer once the evidence, rather than the positioning, speaks.
