AI Stocks Just Lost Trillions. Small Investors Have One Advantage Wall Street Doesn't

Thursday was the kind of day that might change people’s minds about their portfolio. The Nasdaq plunged 5.5% in its worst session in 19 months, with Nvidia down more than 9%, the semiconductor index off more than 12%, and around $3 trillion wiped off the value of S&P 500 businesses. The Nasdaq completed the day more than 10% below its Oct. 6 peak, officially in correction territory.

Then Friday arrived, and technology bounced. Nvidia gained 2.8%, AMD jumped 11%, and the Nasdaq finished 1.1% higher. That probably felt like a relief to anyone who had spent Thursday watching months of gains disappear. It did not change much. The Nasdaq still finished the week down 3.4% and recorded its fourth consecutive weekly decline.

This is usually when the individual investor starts feeling disadvantaged. Wall Street has the research departments, the trading desks, the expensive data, and people sitting in front of screens all day. Surely the professionals know what to do next. I am not sure that is the right way to think about this moment. The small investor has something many professional investors would probably pay quite a lot for right now. He does not have to do anything.

Wall Street Sometimes Has to Sell

One of the more interesting things happening underneath this selloff is what is going on inside hedge funds.

Technology-heavy long-short funds lost more than 4% on Thursday alone, according to Goldman Sachs calculations quoted by Reuters. Their returns for 2026 are presently around flat, after being as high as 24% in June. Other hedge fund techniques were also affected, as Reuters reported that several large multi-manager firms have been cutting leverage and trimming investment teams. After its worst month since March 2020, $17 billion hedge fund Walleye Capital warned investors that it was shrinking part of its equities operation.

Professional investors do not always get to make decisions purely on what they think a company will be worth three years from now. They have risk limits. They have investors who can redeem. They may have leverage. They have bosses looking at daily losses. Portfolio managers who were comfortable owning a position at 5% of a fund when volatility was low may suddenly find the same position too large when the market starts moving 5% in a day.

None of that necessarily tells you anything about what the company is worth. It can still push the share price down.

This is something individual investors often misunderstand. They see a large institution selling and assume somebody on Wall Street knows something they do not. Occasionally that is true. Other times the seller is simply solving an entirely different problem. He may need to reduce gross exposure, meet a risk limit, or sell the position everyone else owns because it is the easiest one to trade.

Reuters reported that hedge funds that had cut exposure before the midterms then chased Wednesday's rally, only to start selling some of those technology positions again after Thursday's collapse. That is not a criticism of hedge funds. This is the reality of managing money within constraints. The person managing their own retirement account does not have those same constraints. That can be an edge if they use it properly.

Doing Nothing Is a Position

After more than 35 years in markets, I know that activity and good investing are not the same thing. When markets move like this, there is enormous pressure to respond. Sell before it gets worse. Buy because it has fallen. Average down because you liked it higher. Chase Friday's rebound because perhaps Thursday was the bottom. You do not have to do any of those things.

You can wait for another earnings report. You can see whether management cuts spending. You can watch whether analysts continue reducing estimates. You can see what happens when the next piece of bad news hits the stock. Most importantly, you can wait until you understand whether the decline has changed the price or changed the business.

Take two companies that have both fallen 30%. One is generating cash, has little debt, continues to grow, and has simply seen its valuation multiple collapse. The other needs regular access to capital markets, has enormous future spending commitments, and now faces a weaker demand outlook. They have suffered the same share-price decline. They do not have anything close to the same risk.

This is particularly important in AI because the selloff has moved well beyond the easy argument that artificial intelligence is either a bubble or the greatest technology ever invented. Technology can be enormously important, and some stocks can still have been too expensive. Data center construction can continue, and some companies financing that construction can still deliver poor returns to shareholders. Nvidia can remain a remarkable business while customers work hard to reduce their dependence on Nvidia's margins.

I have written about all those issues before. What the last few weeks have done is move them from theoretical questions into the share prices. Now investors get to find out which assumptions mattered.

Let Wall Street Give You the Price

The temptation after a fall like this is to decide that everything is finally cheap. I would resist that. Forced selling can offer opportunities, but forced selling doesn’t automatically create value. I want to know what the balance sheet looks like and how much cash the business generates after capital expenditure. And have earnings stopped falling? I am also observing something a lot simpler: how the stock performs as the news gets worse.

If a company reports another disappointment and the stock barely moves, I get interested. Somebody who wanted out may already be gone. Expectations may finally have fallen far enough. If the company produces apparently good numbers and the shares still cannot hold a rally, I am much more cautious because the market may still be working through an ownership problem or expectations may still be too high. There is no reason an individual investor needs to predict the exact bottom.

In fact, trying to do that often throws away the advantage I am talking about. Wall Street may need to move quickly because capital is being pulled, risk is being cut or somebody is worried about tomorrow morning's meeting. You can buy 20% of the position you eventually want. You can hold cash. You can wait a month. You can change your mind without explaining yourself to an investment committee.

Friday's bounce-back is a nice illustration. The semiconductor index gained 4.2% after Thursday’s rout, but the Nasdaq concluded the week still in correction territory, marking its fourth straight weekly fall. I don’t know if Friday marked the start of a rebound or just the first bounce in a market that has more work to do.

What I want is a business I understand, a balance sheet that gives me time to be wrong and a price that offers enough room between what I am paying and what I think the company is worth.

That is where the individual investor can compete. Wall Street probably has better information than you. It almost certainly has faster information than you. What it does not always have is your freedom to wait. When markets become disorderly, that freedom becomes valuable. 

Your advantage over Wall Street is not knowing what happens next. It is being able to do nothing while Wall Street is being forced to do something.
