What Happened?
A number of stocks fell in the afternoon session after rising geopolitical tensions from the Iran war, threatened to disrupt critical supply chains.
The conflict raised alarms beyond oil prices, with a significant risk looming over the supply of essential gases, such as helium, which are vital for semiconductor manufacturing. Major chip fabricators, including Taiwan Semiconductor Manufacturing Company, Samsung Electronics, and SK hynix, were projected to face significant production challenges in the event of a supply constraint.
Such disruptions would create cascading effects across the tech industry, impacting the production of everything from Apple's iPhones to Nvidia's advanced AI servers. The uncertainty has contributed to a broader market downturn, pushing the Nasdaq into a correction.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Western Digital (WDC)
Western Digital’s shares are extremely volatile and have had 47 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 4 days ago when the stock dropped 7.2% on the news that investors reacted to news of Google's new TurboQuant algorithm, a tool that threatens to significantly reduce memory requirements for artificial intelligence models.
The market's interpretation is that this increased efficiency could lead to a structural decrease in demand for memory chips, sparking a sector-wide sell-off. Sandisk saw its stock fall by as much as 8%. The concerns generated by Google's announcement overshadowed recent strong earnings from memory-makers. Adding to the sector's headwinds are reports that competitor SK Hynix is considering a potential $14 billion U.S. listing, which would increase competitive supply pressure in the market.
Western Digital is up 33.8% since the beginning of the year, but at $251.10 per share, it is still trading 20.8% below its 52-week high of $316.93 from March 2026. Investors who bought $1,000 worth of Western Digital’s shares 5 years ago would now be looking at an investment worth $3,836.
