Quick overview
- July began with a decline in stock market indices, particularly the Nasdaq, which fell by 0.6% due to underperforming chip stocks.
- AI-related stocks Sandisk and Micron experienced significant losses of 8% and 6%, respectively, amid investor concerns about future performance.
- Despite a strong first half of 2026 for semiconductor stocks, analysts warn that the rapid growth may not be sustainable, leading to increased scrutiny from shareholders.
- The current market remains bullish, driven by AI, but investors are advised to monitor economic indicators closely as growth may slow in July.
July started off poorly for the stock markets indices, particularly Nasdaq with a loss of 0.6% as chips stocks faltered at the beginning of the second half of 2026.
AI-related stocks Sandisk (SNDK) and Micron (MU) fell sharply on Wednesday, losing 8% and 6%, respectively. These stocks climbed quickly late last month but are suffering extra scrutiny from investors as shareholders start to worry about what the second half of the year might look like for this sector.
The Nasdaq Composite lost 0.6% as trading began on Wednesday, and the S&P 500 fell 0.4%, and the Dow Jones Industrial Average lost 0.3%. Many of the major losses in the market for the morning came from stocks linked to artificial intelligence, including Broadcom (down 2%) and Nvidia (down 3%).
Investors Fear that Chips Stocks May Underperform
Semiconductor and chips stocks did so well in the first half of 2026 that there is a risk they may fall off in the second half. Sandisk gained more than 850% in the first six months of the year, and Micron grew by 277%, and for many analysts, it simply does not seem like that kind of sustained growth is going to last much longer.
The rapid growth of many chip stocks caught investors by surprise, and Sandisk, with its storage products that benefit from AI market growth, was one of the surprise success stories this year so far. However, shareholders are scrutinizing these stocks closely, and many expect them to drop sharply at any time. The concern is that the market is in a bubble and could burst unexpectedly, so it is reasonable for traders to take their profits and run before that happens.
That is what we saw on Wednesday morning, as chip stocks grew quickly in recent days and then lost some of their investors who had made a tidy profit. Now, investors should pay close attention to earnings reports and economic readings that indicate where the market and economy are heading. If indicators still point toward a growing economy, then many of those investors may jump back in and invest in these rapidly rising chip stocks and related assets.
The current market is AI driven and is very bullish, according to industry experts. That may not be sustainable over the long run, but for now, these stocks are still very elevated. The latest U.S. jobs report showed unexpected growth, and added jobs increased to a two-year high. This is promising for the economy, but investors should not expect a similar occurrence next month. With 9,000 added jobs for June, the market is healthy, but the level of growth may pare back slightly for July as the market levels out.
