November 5, 2026, may go down in history as the day the artificial intelligence (AI) bubble burst. That is the assessment given by Edward Dowd, founder of the analytics firm Phinance Technologies and author of the book Cause Unknown.
On that day, the VanEck Semiconductor ETF (SMH), which bundles shares of chipmakers, lost 10%, and the Nasdaq 100 index fell 6.36%. Trader Lofty called it the start of the worst crash in history. Investor Jason Calacanis, by contrast, saw it as the best buying opportunity in a generation. We break down what happened and what it means for traders.
November 5
The main blow landed on semiconductor manufacturers. Edward Dowd called them the suppliers of "picks and shovels" for the entire AI industry. Without chips, you cannot build a data center or train a model, so their shares show whether the market believes in the AI boom. On November 5, the market showed that it has doubts.
By Dowd's calculations, the sector has fallen 32% from its June peak, which it reached after a rapid rally. On the day of the crash, the SMH fund sharply broke through its July low. For technical analysis, this is a turning point. As long as the price holds above a strict low, the decline is considered a correction. After a breakout, it is already a downtrend. That is precisely why Dowd called November 5 the day the bubble burst technically.
Dowd explained what is happening through reflexivity. This is when rising prices attract new money, and that money pushes prices even higher. Now, in his view, the mechanism has reversed: the decline triggers selling, and selling amplifies the decline. The credit market was the first to warn of the danger.
What this means for the market
If Dowd is right, November 5 marked the beginning of a long slide rather than a one-off shakeout. He himself allowed that the market will still rise on hopes. But each such rebound, by his logic, will become a reason for new selling.
Bull Theory blamed the Democrats for the crash. A trader under the handle Lofty compared the situation to the dot-com collapse and the 2008 mortgage crisis. Not everyone agrees that the market is in panic. Morgan Housel, author of the book The Psychology of Money, wrote that this is the worst decline since the previous one that everyone has already forgotten.
Investor and host of the All-In podcast Jason Calacanis called the crash a once-in-a-generation buying moment. He believes that the Democrats are not as radical as the Republicans portray them and will not allow markets to collapse themselves, because they do not want to be held responsible for crashing retirement accounts and layoffs. Calacanis urged support for moderate politicians in the party, such as Rahm Emanuel.
For traders, the picture looks like this. The key level for SMH is around $443, where the 200-day smoothed moving average runs. If the fund holds above it, a rebound is possible, the one Dowd spoke about. If it breaks through, selling may intensify, and the "bubble burst" scenario will receive new confirmation.
Where the money went
While the technology sector was falling, gold miners were rising. The XAU gold mining companies index added 0.59% on November 5. Otavio Costa, founder of Azuria Capital LLC, drew attention to this.
According to Azuria Capital, since 1985 this combination has occurred only 11 times. The last time was in March 2020, at the height of the pandemic-driven crash. All other instances came in 2000–2001, when the dot-com bubble was bursting.
Costa recalled that both times these were important turning points for gold and mining stocks. During the dot-com collapse, miners decoupled from the broad market and began a multi-year rally. Long-term investors, he said, understand what to do in such a situation.
For traders, this is the second important takeaway. If November 5 really repeats the 2000 scenario, money will flow out of AI stocks into defensive assets, and gold and miners will be the winners.
Cryptalist analysis: The SMH fund breaking through its 200-day moving average while gold miners rise in sync is a classic signal of capital rotation from cyclical technology assets into defensive ones. The rarity of such a combination (11 times since 1985) gives it heightened significance as an indicator of a change in market regime. However, the durability of the trend will be determined not by emotions but by SMH's ability to hold above the $443 zone — that is precisely the level that will become the dividing line between a correction and a full-fledged bear market.
