Equity Selloff Cascade or Correction? Signals Investors Should Watch

Wall Street lost about $2.3 trillion in a single session on 5 November 2026, according to Bloomberg. The Nasdaq Composite fell 5.52% and the S&P 500 dropped 4.36%. Today the Nasdaq bounced roughly 1.8%, and Bloomberg Intelligence commodity strategist Mike McGlone says that bounce changes nothing about where an equity selloff cascade may be heading.

That is the real debate now. One view is that this is a contained correction, a sharp but valuation-driven reset in AI stocks. The other is that it marks the first stage of a liquidation that spreads across stocks, crypto and metals. If you misread which one it is, you either sell into a temporary low or hold through the early phase of something much larger.

Here is a framework for judging any market-wide liquidation: what tends to lead, what follows, and which signals would confirm or refute the cascade thesis. McGlone’s figures come from his interview with David Lin and are attributed to him. Market data comes from named outlets and is current as of 6 November 2026.

What is McGlone actually arguing, and how do the numbers hold up?

McGlone’s case is blunt. He sees stocks as the main driver of a broad liquidation that has only just begun. In his view, metals, crypto and other assets follow equities lower into year-end and into next year.

Mike McGlone, Bloomberg Intelligence: A 20% equity drawdown is “nearly unavoidable”, given how stretched valuations have become relative to GDP and debt.

His valuation argument rests on two claims. Market capitalisation to GDP sits at a century high, he says, and market capitalisation to US debt is at its highest since 2001. He puts total stock market value at about $81 trillion, against a $83 trillion peak this year, with US debt near $40 trillion.

Set those claims against independent data and the picture gets messier. The Buffett indicator measures total stock market value against the size of the economy. StockDoz put it at about 204.6% on 3 November, based on roughly $95.6 trillion in market value against $33.0 trillion of annualised GDP. FinanceBuzz reported closer to 290%. McGlone’s market-cap figures come from a different data series, and his method is unspecified.

Several interview figures also drifted from later reporting.

The later figures are the ones to rely on. The Nasdaq closed at 24,315.00, the Nasdaq 100 fell 6.4%, and the composite ended more than 10% below its 6 October record, which puts it in technical correction. Retail investors sold a net $338 million of US stocks before late buying cut that to $151 million (Yahoo Finance/WSJ).

What the valuation reading tells you is that the market is priced with little margin for error. It does not tell you when, or whether, a reset begins.

The July chip rout, the worst month for semiconductors since 2008, already showed how a crowded AI trade can reprice sharply while the broader index stays flat.

Does crypto lead, then metals, then stocks? Testing the leadership order

The case for the sequence

A tidy sequence is appealing because it promises an early warning. McGlone lays one out:

Crypto peaked first, trading near $75,800 on 6 Nov, before metals broke below $6.40 per pound and stocks returned to their 200-day moving average.

1. Crypto peaked first. His confirmation signal: Bitcoin failing to hold $80,000.
2. Precious metals came next. His trigger: copper breaking below support near $6.40 per pound.
3. Stocks are now following. The Nasdaq and copper have both returned to their 200-day moving averages, which track the average price over roughly the past 200 trading days.

The first trigger has already fired. Bitcoin traded near $75,800 on 6 November, with an intraday low around $75,255 (CCN). More than $1 billion in crypto derivatives positions, mostly bets on higher prices, were liquidated over 24 hours, according to Yahoo Finance. McGlone also floats a 50% retracement of the roughly 100% gain since the 2022 low.

Where the evidence pushes back

The sequence weakens under scrutiny. Benzinga reported unusually high 50-week correlations among gold, copper and the S&P 500, meaning they have tended to move together. In a synchronised deleveraging, metals can fall alongside equities rather than ahead of them.

McGlone’s own framing holds both ideas at once: stocks as the driver, and crypto as the early signal. The evidence from this episode leans towards AI-equity and credit stress leading, with crypto liquidation amplifying the damage rather than forecasting it. The research also does not establish the exact early-October Bitcoin peak, so the size of crypto’s head start is unclear.

If you use Bitcoin or copper as an early-warning gauge, treat them as one input among several. In a forced deleveraging, every correlated asset can fall together, so metals may offer less protection than you expect.

How does a selloff become a cascade? A framework for market-wide liquidation

A violent one-day drop is the part you see on screen. The cascade is the chain of forced selling behind it, where each stage pushes the next one along.
