Market Update

Over the past year, investors have been forced to repeatedly answer the same question: what is the market’s biggest risk? The answer has changed several times, and each shift has reshaped market leadership.

Late in 2025 and early 2026, artificial intelligence became the market’s primary uncertainty. Investors questioned whether AI would erode software pricing power and weaken competitive moats as AI made it easier to replicate once-differentiated products.

By the spring, technology took a back seat to geopolitics. The U.S. conflict with Iran briefly became the market’s dominant narrative, raising concerns about oil prices, inflation, and global growth. But as energy markets remained orderly and fears of a prolonged supply disruption faded, investors quickly turned their focus back to fundamentals.
