The investment landscape surrounding artificial intelligence (AI) is currently experiencing a significant shift. Investors are no longer fixated on hastily acquiring stocks from chip - making behemoths. Instead, they are redirecting their focus towards stocks of "shovel sellers" within the technical infrastructure realm. This change indicates that the beneficiaries of AI - related trading have broadened, now encompassing a wider array of links along the industrial chain.

In 2025, data storage companies have emerged as the dominant force on the S&P 500 gainers' list. Firms like Western Digital (which owns SanDisk) have particularly stood out, while NVIDIA's stock performance has shown signs of weakening. Although the consensus on Wall Street remains that AI will continue to be the overarching investment theme, concerns regarding potential oversupply in the market have started to surface.

As we look ahead to 2026, the data storage sector is anticipated to maintain its popularity. However, some of this year's top - performing companies may encounter difficulties as their boom periods draw to a close. On the other hand, companies such as Pure Storage Inc. are viewed as having significant upside potential.

In the meantime, construction and power stocks are emerging as new investment hotspots. Companies like Quanta Services Inc. have been receiving widespread attention from investors. Additionally, the cooling system and software sectors are also areas that investors should keep a close eye on. Cooling system - related companies like Vertiv Holdings Co. and software firms like Snowflake Inc. have both been drawing considerable market attention.

Finally, a word of caution: the investment market is inherently risky, and investors should always proceed with due diligence and caution.
