Podcast Summary: Unhedged – "Nvidia's Crazy Day"
Date: November 20, 2025
Hosts: Katie Martin & Rob Armstrong (Financial Times)
Episode Overview
The episode revolves around Nvidia's "monster" earnings report and its outsized influence on current market sentiment amid shaky financial conditions. Katie Martin and Rob Armstrong dissect whether Nvidia’s performance has truly "saved" the markets or merely provided a temporary mood boost. They dig into the AI stock bubble narrative, implications of recent US jobs data, how professional investors are positioning themselves, and the real-world consequences if an "AI bubble" bursts.
Key Discussion Points & Insights
1. The Market Mood: From Euphoria to Anxiety and Back
-
Recent shift: Markets have been unstable, swinging from optimism ("la la la, everything is awesome") to anxiety about a crash ([00:39]).
-
Nvidia’s impact: Nvidia released massive, better-than-expected earnings, momentarily reversing the negative sentiment.
“And then, boom, along comes Nvidia, world’s biggest, most gigantic, most ginormous chips company in the States. [...] it put out incredible earnings. Like it's just making insane amounts of money. And that has kind of lifted the mood again.” — Katie Martin [02:13]
2. Is Nvidia Preventing a Crash or Masking a Bubble?
-
Strong fundamentals vs. sustainability concerns:
Rob notes Nvidia’s surging revenues justify its stock price if growth lasts. The risk is whether such growth rates are sustainable ([02:55], [03:46]). -
Bubble thinking: Many in the industry see bubbly signs—concentrated money flows and exuberant projects—but are wary of stepping away too early and missing further gains.
“The worry is not Nvidia’s price to earnings ratio. [...] The worry is the revenue and growth rate of that revenue is ultimately unsustainable.” — Rob Armstrong [03:46]
“You don’t want to be early. You don’t want to say, okay, I’m getting out of these names, or I’m going to short them. Because the pain when you have that final, you know, push higher in these stocks, which could be another 10, 20%. I mean, or more guessing.” — Katie Martin [04:22]
3. Investor Psychology and Bubble Dynamics
-
FOMO and regret:
Katie relays an anecdote about an investor chastising their advisor for missing out after taking some money off the table too soon ([05:26]). -
Cherry-picking positive data:
Rob and Katie discuss how both equities and bonds markets latch onto whatever news bolsters their preferred narrative ([08:25], [09:17]).“That’s bubble thinking, Katie. Right. Whatever happens is good news. That’s bubble thinking.” — Rob Armstrong [09:17]
4. US Jobs Data and the Fed: Mixed Messages
-
Surprise jobs gain with rising unemployment:
- Big jobs number (+119,000), unemployment rate ticked up from 4.3% to 4.4% ([06:40], [08:11]).
- Mixed implications for rate cuts; markets read the tea leaves according to their biases.
“The report is making markets move. Equities and bonds seem to be picking the parts of the job release they like. [...] And do you know what kind of thinking picks the good stuff in one area and picks the bad stuff in the other area and doesn’t look at the two of them together. That’s bubble thinking, Katie.” — Rob Armstrong (quoting Seema Shah’s note) [08:25]
5. Risks in Private Credit and Esoteric Assets
-
There’s lingering unease:
“Investors still haven’t got over that little string of failures that was related to the private credit markets a few weeks ago. People are still on high alert [...] At what point is this a symptom of something bigger which is like crappy overly easy lending standards in a huge gold rush into private markets?” — Katie Martin [09:33]
6. How (and Whether) to Hedge Against a Bubble Pop
-
Hedging strategies discussed:
- Rotating into "anti-tech" or staples stocks, more "boring" assets ([13:02]).
- Geographical diversification (e.g., China) or picking AI infrastructure rather than direct AI stocks ([12:24]).
- Rob cautions these strategies might offer little protection in a true crash:
“If it blows up, like, spectacularly, all of those things will get ironed out. Like, everything will get killed in the short term.” — Katie Martin [14:25]
-
Cash as a true hedge:
- Rob stresses cash (short-term bonds, deposits) is the only sure hedge in a crisis ([18:02]).
- But warns against ever going "all out" of equities:
“Equities are the best asset they have been through history. If you have anything like a long time horizon, you want to own some of those things.” — Rob Armstrong [18:50]
-
Market selloffs and liquidity:
- During a crash, investors will sell whatever is liquid and easy—often the same big stocks like Nvidia ([15:24], [16:06]).
“When there is some sort of pop in markets [...] investors don't necessarily sell what they want to sell. They sell what they can sell.” — Katie Martin [15:24]
7. Perspective: Don’t Predict, Prepare
-
Both hosts admit the unpredictability of bubbles and shy away from confident forecasts.
“I’m very much in favor of just saying I don’t know. But if I were to place a bet on this, I would say the likelihood of some sort of correction, not necessarily a crash, but a correction next year is very high.” — Katie Martin [17:46]
Notable Quotes & Moments
-
On market psychology:
- “Psychologically you get very upset by the money that you fail to make that was there right in front of you, of course. And, and you don't see the big picture.” — Katie Martin [06:08]
-
On investor complacency and froth:
- “That’s bubble thinking, Katie. Right. Whatever happens is good news. That’s bubble thinking, right?” — Rob Armstrong [09:17]
-
On safe-haven strategies:
- “Never want to be all the way out of the equity market. Never. It just doesn’t pay.” — Rob Armstrong [18:50]
-
Soundbite on crash psychology:

Tone and Takeaways
The conversation is candid, lightly humorous, occasionally self-deprecating, and clear-eyed about the unpredictability of markets. The hosts mix technical insight with human observations about psychology and herd behavior.
Main takeaway:
Nvidia’s results may have given markets a temporary lift, but underlying risks and speculative froth remain. Both hosts recommend prudent caution: hold diversified assets, maybe edge up cash, but don’t try to time the impossible. Above all, acknowledge what you don’t know—and watch out for the next “handbag” moment of market silliness.
