The Nasdaq 100 lost more than $2 trillion in market value in October 2026, snapping a two-month winning streak, after a run of earnings reports showed the largest technology companies spending faster on artificial intelligence than they are earning from it. Intel fell 29 percent in a single day, Alphabet had the worst day in its history, and Meta reported its first cash outflow in more than a decade. If you hold a target-date fund or an S&P 500 index fund in a 401(k), you own all of those companies, because the seven largest stocks now make up roughly 30 percent of the index and more than 80 percent of 401(k) plans default savers into cap-weighted funds. This article explains what happened, how much of a typical retirement account is exposed, why gold fell alongside stocks on Friday and what that has meant historically, and whether moving part of a 401(k) into a gold IRA makes sense for a saver within ten years of retirement.
Key Takeaways
- The Nasdaq 100 fell more than 5.8 percent in October and shed over $2 trillion in value, per Reuters, with the index's worst single days on October 22 and October 30 after AI-spending disclosures from Meta, Alphabet, Amazon and Intel.
- The seven largest US stocks are about 30 percent of the S&P 500, and technology plus communication services are about 45 percent, per Yardeni Research. More than 80 percent of 401(k) plans default new savers into cap-weighted target-date funds that hold that concentration automatically.
- J.P. Morgan estimates AI capital spending will reach about $900 billion in 2026 and $5.5 trillion by 2030. The IMF warned in October that disappointing AI returns could trigger a market correction.
- Gold fell to about $3,870 on Friday, a one-year low, as funds sold it to meet margin calls on tech positions, then rebounded above $3,950 on Monday. The same pattern played out in 2008, when gold fell roughly 30 percent in the panic and then rose to a record by 2011 while the Nasdaq took until 2015 to regain its 2000 high.
- Metals pay no dividend or interest and their value moves. This is market commentary, not financial advice.
What Happened to the Nasdaq in October 2026?
Two days did most of the damage. On October 22 the Nasdaq Composite fell 2.6 percent, its steepest drop since early June, after Meta reported strong results but disclosed its first cash outflow in over a decade and a plan to issue a new class of shares to fund AI construction. The stock fell 7 percent. Chipmakers Intel, AMD, Sandisk and Marvell each fell more than 8 percent, and the Philadelphia Semiconductor Index lost 6.7 percent.
On October 30 it happened again. The Nasdaq fell about 2.5 percent to its lowest level in nearly three months. Intel dropped nearly 29 percent, the biggest one-day fall in the company's history, after it said it would burn cash this year on a weak PC market and heavy spending to expand production. Alphabet was still absorbing a record selloff from the day before, triggered by a sharp increase in its own cash outflows. Amazon signaled yet another capital spending increase for next year. The chip index fell 7 percent, Nvidia 3.7 percent, Dell 10 percent. Reuters calculated that the Nasdaq 100 was on course to lose just over $1 trillion that day alone and more than $2 trillion for the month, slightly more than the entire market value of SpaceX.
The money did not vanish. It rotated. Health care stocks hit a record high the same day, consumer staples rose 1.6 percent, and Chevron and Exxon gained on strong earnings. Angelo Kourkafas of Edward Jones described it as a move into defensive sectors supported by an "above-trend" pace of growth in the parts of the economy that had been lagging. The point for a retirement saver is that the rotation happened inside the market. A cap-weighted index fund cannot rotate. It holds the winners of the last decade at the weight they reached, and it rides them down.
Why Did AI Stocks Fall? The Spending Problem
The companies at the center of the selloff are not failing. Most beat earnings estimates. What spooked the market was the gap between what they are spending and what they are getting back.
J.P. Morgan estimates that global AI capital spending will reach about $900 billion in 2026 and $5.5 trillion by 2030. Morgan Stanley puts next year's AI infrastructure spending above $1 trillion. J.P. Morgan's analysts noted that the amount Amazon, Alphabet, Meta, Oracle and Microsoft will spend on AI this year alone roughly equals everything they had spent since ChatGPT launched in November 2022. Meta is planning a $97.5 billion capital raise. Microsoft is preparing a roughly $25 billion bond sale. Companies that generated cash for twenty years are now borrowing to build data centers, and investors are starting to ask when the buildings pay for themselves.
The International Monetary Fund asked the same question in its October 2026 Global Financial Stability Report, warning that "disappointing AI investment returns could trigger a market correction," particularly where borrowing is concentrated. Joe Saluzzi of Themis Trading put it in plainer terms on Friday: "A lot of them kind of got ahead of themselves. It's all earnings based and right now, they're not producing."
Add the rate backdrop. The Fed held rates at its October 28 meeting, but two of twelve voters wanted a hike, and LSEG data show markets pricing more than half a percentage point of further increases by mid-2027. Debt-funded construction gets harder to justify at every step up in borrowing costs.

How Much of Your 401(k) Is in These Seven Stocks?
More than most people think, and almost none of them chose it.
Per Yardeni Research, the seven largest US stocks, Apple, Microsoft, Nvidia, Amazon, Alphabet, Meta and Tesla, make up about 30 percent of the S&P 500's market value. Add the rest of the information technology and communication services sectors and the figure is about 45 percent. An S&P 500 index fund is, by construction, nearly half a bet on one theme.
Most retirement money is in exactly that kind of fund. Fortune reported in September that more than 80 percent of 401(k) plans default new participants into target-date funds, and the large majority of those are built on cap-weighted indexes. About 54 percent of US households have a 401(k), per the Federal Reserve. Valentin Haddad of UCLA Anderson told Fortune that Tesla alone can be 3 to 4 percent of some 401(k) portfolios, and that the current setup is "concentration and size, all packed together, even more than there was during the dotcom bubble." Vanguard's Jim Rowley described the mechanism without judgment: "Market cap weighting isn't a choice, it's not a methodology, it just is." As a stock grows, the fund buys more of it. The fund that made savers rich on the way up is the same fund that holds the most of them at the top.
For a deeper look at how that concentration built up, see our August piece on why your index fund is more exposed than you think.
Do Target-Date Funds Protect Savers Near Retirement?
Less than the name suggests. A target-date fund reduces its stock allocation as the target year approaches, but most still hold about 55 percent in stocks at the target date, and the stock portion is the same cap-weighted index. In 2008, funds dated 2010, meant for people retiring within two years, lost more than 30 percent. In 2022, funds dated 2020 lost 13 percent, because their bond holdings fell alongside stocks when rates rose. Ron Surz, who has tracked target-date performance for years, summarized it plainly: "Protecting those near retirement should be a requirement, but it's not."
That matters because of timing. A 35-year-old who loses 20 percent has thirty years to recover. A 65-year-old who loses 20 percent in the year withdrawals begin may never recover, because every dollar withdrawn during the decline is a dollar that cannot participate in the rebound. We covered that math in May in why a correction matters more to retirees than anyone else. October was a reminder that the math is not theoretical.
Why Did Gold Fall With Stocks, and What Happened Last Time?
Gold did not escape Friday. It fell more than 3 percent to about $3,870, its lowest in a year, and silver fell nearly 6 percent to under $49. That surprises people who expect gold to rise when stocks fall. Here is what was happening.
When leveraged funds take losses on technology stocks, their brokers demand cash. The fastest way to raise cash is to sell what is most liquid, and gold is one of the most liquid assets on earth. Waleed Said of GivTrade told Kitco that investors "sold gold to cover margin calls elsewhere." Reuters reported the same mechanism the week before. Gold was sold not because anything changed about gold, but because it was the easiest thing to sell. By Monday morning it had rebounded more than 2 percent to about $3,960.
This has happened before, and the sequel is worth knowing. In 2008 gold fell roughly 30 percent from its March high as funds liquidated everything during the financial crisis. It then rose for three straight years to a record above $1,900 in September 2011, a gain of more than 150 percent from the 2008 low. The Nasdaq, by contrast, did not regain its March 2000 peak until 2015. In March 2020 gold fell about 12 percent in a week during the pandemic liquidation, then set a new record five months later. The pattern is consistent: in a forced-selling panic, gold goes down with everything else, and when the panic ends, it is one of the first assets to recover, because the reasons people own it, debt, inflation and distrust of paper promises, are usually worse after a crisis than before it.
Gold is down about 1 percent from a year ago and roughly 29 percent below its January record of $5,608. Central banks have not stopped buying. The forced sellers are hedge funds; the steady buyers are the institutions that do not use leverage.
Should You Move Part of a 401(k) Into Gold After a Selloff?
Three things, in order.
Find out what you actually own. Open the fund fact sheet for your target-date or index fund and look at the top ten holdings. If seven technology companies are a quarter or more of it, you have a concentration you did not choose. Knowing that is the first step; most savers never look.
Decide how much of your retirement should depend on AI paying off. The companies may well succeed. J.P. Morgan's John Bilton said, "It may be that we've overestimated how strong the growth might be, but they're not going negative in aggregate." But a retirement account is not the place to make a concentrated bet on one outcome, in either direction. The question is not whether to own these stocks, it is whether to own them at 45 percent.
Add something that is nobody's debt. A diversified retirement account holds assets that do not all fall for the same reason. Physical gold and silver are not funded by borrowing, do not report earnings, and have historically recovered from liquidation panics faster than the stocks that caused them. That is what a gold IRA is for. A 401(k) to gold rollover moves part of an existing retirement account, by direct transfer, into a self-directed precious metals IRA that holds physical gold and silver coins and bars in your name at an insured depository. Done through an approved custodian, it is not a taxable event and carries no early-withdrawal penalty. Most USA Capital Gold clients move a portion, not the whole balance, and keep the rest of their plan intact.
The Bottom Line
The Nasdaq 100 lost more than $2 trillion in October because the largest technology companies are spending on AI faster than they are earning from it, and the market has started to price the risk that the payoff comes late or small. Most 401(k) savers hold those companies at 30 to 45 percent of their stock allocation through cap-weighted funds they were defaulted into, and target-date funds have historically not protected people near retirement from this kind of decline. Gold fell on Friday because it was sold to raise cash, the same thing that happened in 2008 before it rose to a record. For a saver within ten years of retirement, the lesson of October is to look at what you own and make sure part of it is an asset that does not depend on a data center paying for itself. For many of our clients, that part is physical gold and silver held in a gold IRA.
Metals pay no dividend or interest and their value moves, so they belong as one part of a diversified retirement plan rather than a replacement for it. This is general information, not financial advice, and the right approach depends on your situation.

Frequently Asked Questions
Why did the Nasdaq fall in October 2026?
A series of earnings reports showed the largest technology companies spending far more on AI infrastructure than they are earning from it. Meta reported its first cash outflow in over a decade, Alphabet had a record one-day drop after disclosing higher cash burn, Intel fell 29 percent in a day, and Amazon signaled another capital spending increase. The Nasdaq 100 lost more than $2 trillion in value for the month.
How much of my 401(k) is in tech stocks?
If you hold an S&P 500 index fund or a cap-weighted target-date fund, roughly 30 percent is in the seven largest stocks and about 45 percent is in technology and communication services combined, per Yardeni Research. More than 80 percent of 401(k) plans default savers into such funds.
Do target-date funds protect you near retirement?
Only partly. Most still hold about 55 percent in stocks at the target date. Funds dated 2010 lost more than 30 percent in 2008, and funds dated 2020 lost 13 percent in 2022 when bonds fell alongside stocks.
Why did gold go down when stocks fell?
Leveraged funds facing margin calls on tech positions sold gold because it is liquid. Gold fell about 3.5 percent on October 30 to a one-year low near $3,870, then rebounded above $3,950 on November 2. The same forced selling happened in 2008 and March 2020, and gold set new records within three years and five months respectively.
Is the AI boom a bubble?
Opinions differ. The IMF warned in October 2026 that disappointing AI returns could trigger a correction, and UCLA's Valentin Haddad says concentration exceeds the dotcom era. J.P. Morgan's John Bilton argues growth may be overestimated but is not turning negative. A retirement saver does not need to settle the debate, only to avoid betting 45 percent of a portfolio on one answer.
Should I move my 401(k) to gold after a stock market drop?
Most savers who add gold move a portion, not the whole account. A 401(k) to gold IRA rollover, done by direct transfer through an approved custodian, is not a taxable event. The right amount depends on your age, timeline, and other holdings; this is not financial advice.
Is gold a good hedge against a stock market crash?
Not in the first days of a forced-selling panic, when gold is sold for cash alongside everything else, as it was on October 30. Over the following months and years it has historically been one of the strongest performers: gold rose more than 150 percent in the three years after its 2008 low, and set a record five months after the March 2020 liquidation. Gold pays no dividend or interest and its value moves.
Can I hold physical gold in a retirement account?
Yes, through a gold IRA. A self-directed precious metals IRA can hold physical gold and silver coins and bars that meet purity standards, stored in your name at an insured depository. Call 1-888-263-8931 to see how a rollover works.
