What Happened?

A number of stocks fell in the afternoon session after markets continued to retreat, as investors re-evaluated the high valuations of stocks that benefited from the artificial intelligence boom. 

After a fantastic run, many of those high-flying AI and technology stocks saw investors take profits: selling shares to lock in their gains. This is often called a "market rotation." Money is moving out of the red-hot tech sector (which some worry has become too expensive) and into other parts of the market that investors may currently deem more stable or reasonably-priced. 

There's a secondary reason for the cautious mood: The long government shutdown came to an end. Though it's typically interpreted as good news, it also means a flood of delayed economic reports will be released. For weeks, investors were "flying blind" without key updates on the economy's health, like inflation data and the jobs report. In typical "sell the news" fashion, investors may also be taking profits and selling in anticipation that the new data would potentially give the Federal Reserve reasons to slow or even pause future rate cuts.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Among others, the following stocks were impacted:

Zooming In On Seagate Technology (STX)

Seagate Technology’s shares are very volatile and have had 20 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 9 days ago when the stock dropped 4% on the news that investors reassessed stretched valuations following a period of strong gains, sparking a broad sell-off. 

The tech-heavy Nasdaq fell as much as 1.6%, with the S&P 500 also declining. The pullback was exemplified by AI firm Palantir Technologies, which dropped over 7% despite reporting better-than-expected sales. This negative reaction to positive news suggests investors are concerned about extreme valuations and are engaging in "long liquidation"—selling positions to lock in profits after a significant rally. Adding serious weight to this caution, leadership at both Goldman Sachs and Morgan Stanley highlighted the possibility of a correction in the equity markets over the next couple of years. Despite the euphoria driven by AI optimism and the promise of future rate cuts, these banks viewed this cooling-off period not as a disaster, but as a necessary and healthy feature of a long-term bull market.

Seagate Technology is up 204% since the beginning of the year, but at $262.23 per share, it is still trading 10.8% below its 52-week high of $293.99 from November 2025. Investors who bought $1,000 worth of Seagate Technology’s shares 5 years ago would now be looking at an investment worth $4,793.
