Tech Stocks Have Lost Over $1 Trillion in Value This Year. Is It Time to Panic -- or Buy?

By Reuben Gregg Brewer – Mar 26, 2026 at 5:15PM ESTKey PointsThe technology sector has been leading the market higher for several years.Investors have a bad habit of pushing investment themes to extremes.When the last technology bubble burst, the pain lasted for years.Wall Street has a very short memory. That's both good and bad, since remembering the emotional and financial pain of deep bear markets would likely keep most people from ever investing again. But forgetting history means you are doomed to repeat it. With technology stocks losing so much value so far in 2026, a little historical review can help you decide if it's time to jump into tech stocks or not. The dot-com bubble was huge More than 25 years ago, a revolutionary technology was set to change the world: the internet. That sounds silly today, given how ubiquitous the internet is now. However, if you are old enough, you remember a time when finding information meant a trip to the library and opening a physical book. Image source: Getty Images. The internet has, indeed, lived up to the hype. The technology has changed the world. But back at the turn of the century, investors had pushed so-called dot-com stocks to amazing valuation levels. Even companies with no earnings could see their stocks soar based just on the number of clicks their websites generated. The bubble eventually burst in 2000, with the tech-heavy Nasdaq-100 losing 80% of its value before it started to turn higher again. The decline took around two years to play out. Those two facts are worth repeating. The decline lasted two years, and it reduced the value of the Nasdaq-100 index by 80%. The current tech drawdown doesn't compare The magnificent seven stocks that have basically led the market higher have pulled back sharply in 2026.

Roundhill Magnificent Seven ETF (MAGS 3.26%) is down about 10% in less than three months. Nvidia (NVDA 4.14%), the poster child for the artificial intelligence sector, is down by a similar amount. MAGS data by YCharts The dollar value of the current tech pullback is large, but the actual percentage decline is still modest by historical standards. In fact, the exchange-traded fund meant to track the so-called Magnificent Seven hasn't even entered bear-market territory, which won't happen until the decline hits 20%. If you are worried about the AI bubble bursting, this decline is nowhere near the point where you would think the bubble has finally popped. That leads to two different views of the situation. More aggressive investors might see the current pullback as a correction. That could make it a temporary opportunity to buy tech stocks again before they resume their upward climb. That view, however, requires you to believe that already high valuations can continue to rise.

The S&P 500 index is trading just 5% below its all-time highs. For reference, Nvidia's P/E is 35x, well above the market and the average for the Magnificent Seven. Only the most aggressive investors should see the current tech pullback as a time to buy technology stocks while they are "on sale." Most investors should tread with caution At the end of the day, the technology sector's pullback in 2026 isn't particularly large. It most certainly isn't enough to suggest that the AI bubble has burst. While it may not be time to panic, more conservative investors might want to consider taking some profits just in case this drawdown actually turns into a technology bear market. And if the AI bubble does actually pop, if history is any guide, the declines could be huge, and it could take years before tech stocks start to turn higher again. That said, the other lesson from the dot-com bubble is that overbuilding during the bubble helped to support the technology's widespread adoption. So there could be even bigger opportunities ahead, including well beyond technology stocks, for AI after the current exuberance fades.Read NextMar 10, 2026 •By Dave KovaleskiCould Buying the Roundhill Magnificent Seven ETF Today Set You Up for Life?Mar 26, 2026 •By Emma NewberyStock Market Today, March 26: Snap Tumbles on EU Child Safety ProbeMar 26, 2026 •By Daniel Sparks1 Software Stock I'd Actually Consider Buying Amid This Sell-OffMar 26, 2026 •By John BallardThe Best Stocks to Invest $1,000 in Right NowMar 26, 2026 •By Howard SmithStock Market Today, March 26: Super Micro Computer Falls After Shareholder Lawsuits Over Smuggling AllegationsMar 26, 2026 •By Keith NoonanSpaceX Could File to IPO as Soon as This Week.
