Stock Market Takes a Big Hit as AI Investments Sell Off

On November 5, the United States stock market had one of its worst days in a long time. Investors who had put money into companies working on artificial intelligence, or AI, quickly started selling their shares. The sell-off wiped out about $2.5 trillion in market value and sent a key measure of investor fear to its highest level in eight months.

The selling was triggered partly by the results of the U.S. midterm elections. The Democratic Party won by a wide margin, and many investors worried that the new balance of power in Washington could slow down the building of AI infrastructure. That uncertainty caused panic among both everyday investors and large professional trading firms known as hedge funds. As a result, the Nasdaq 100 index — which tracks many big technology companies — fell 6.4% in a single day.

Wall Street has a tool called the Cboe Volatility Index, often called the VIX or the 'fear gauge.' It measures how nervous investors are about the market. On November 5, the VIX jumped nearly 12 points to reach 28.36, its highest level in eight months. That was its biggest single-day jump in more than a year and a half. When the VIX is high, it means investors are very worried about the future.

Phone lines at major banks and investment firms were flooded with calls. John Flood, a senior official at Goldman Sachs, said in a note that investors were bombarding his team with questions. Another official at a large Wall Street bank said investors were growing more and more anxious as the day went on. People were looking for answers about what had just happened and what might come next.

The day before, markets had actually gone up. Investors seemed calm and even hopeful after the election results came in. But by November 5, the mood had completely changed. Steve Sosnick, a chief strategist at Interactive Brokers, described the sudden shift by saying that one day no one felt they needed protection, and the next day everyone was panicking for it.

Hedge funds were hit especially hard. Goldman Sachs reported that large hedge funds lost a significant amount of money because they had invested heavily in big AI companies. Technology and media-focused funds were down 2.6% compared to the same time the previous year. Jim Carroll, a wealth adviser in South Carolina, summed up the day by saying, 'The steamroller showed up today.'

Everyday retail investors — regular people who invest through apps or brokerage accounts — also played a big role in the sell-off. Normally, when the market drops, retail investors tend to 'buy the dip,' meaning they buy stocks at lower prices hoping they will rise again. But on November 5, that did not happen. Viraj Patel, a strategist at Vanda Research, noted that retail investors were on track for their biggest day of selling since the Covid-19 market crash.

Adding to the pressure, special funds called leveraged ETFs were expected to sell about $47 billion worth of stocks near the end of the trading day. This was set to be the second-largest sell-off of this type ever recorded going back to 2006. Most of that selling was focused on technology and AI-related funds. These funds are built to react automatically when markets get more volatile, which can make price drops even worse.

Analysts said the big question now is whether investors will permanently change how they feel about AI investments. If people decide that AI stocks were overvalued all along — and not just reacting to short-term election news — that could cause much longer-lasting damage to the market. For now, uncertainty remains high, and many investors are waiting to see what happens next in both Washington and on Wall Street.
