Two Signals That Will Determine Whether BAI’s 61% Rally Can Continue

The iShares A.I. Innovation and Tech Active ETF (NYSEARCA:BAI) just got a jarring reminder that AI momentum runs in both directions. After ripping about 36% year to date, BAI dropped nearly 6% in a single week, closing near $45 before a bounce back to about $47 on Tuesday. That kind of chop, inside a year still up roughly 61% over the trailing 12 months, is why BAI holders need a focused, name-level watchlist right now.

BAI is an actively managed thematic fund from BlackRock built around companies enabling AI: chip designers, foundries, memory makers, optical component suppliers, and hyperscale platforms. It carries an expense ratio of 0.73%, which is steep for a passive investor but consistent with active thematic products. The concentration is meaningful: the top 10 holdings account for about 44% of net assets, and eight of those 10 are semiconductor or semi-equipment names.

The Macro Factor: The 10-Year Treasury Yield

The single macro variable most likely to move BAI over the next 12 months is the long end of the Treasury curve, specifically the 10-year yield. It is hovering near 4.6%, near the top of its 12-month range and grinding back toward the spring high near 4.7%. That matters because BAI’s holdings are long-duration cash-flow assets. When the discount rate rises, terminal-value-heavy names like Nvidia, AMD, and the equipment makers get repriced first.

The pressure is coming from the long end, not the Fed. The funds rate has held at 3.75% for roughly seven months following 75 basis points of cuts, and Core PCE printed near the top of its 12-month range in May. Sticky inflation is what is keeping the long end elevated. Watch the daily FRED release for DGS10 and the monthly Core PCE print from the BEA. A break above roughly 4.75% on the 10-year would likely take another leg out of AI multiples the way the late-2022 yield spike did to growth stocks.

The Fund-Specific Factor: Hyperscaler Capex and the Memory Cycle

BAI’s portfolio is a bet that AI infrastructure spending keeps compounding. Broadcom is the top position at about 6%, followed by Nvidia at roughly 5%, SK Hynix at 5%, Taiwan Semiconductor near 5%, and Tower Semiconductor around 4%. Add Lam Research at 4%, AMD near 4%, and Micron around 3%, and the fund is essentially a levered call on hyperscaler orders and HBM memory pricing.

The signal to monitor is the quarterly capex guide from Alphabet, Microsoft, Meta, and Amazon, released alongside earnings. Eric Jhonsa put it cleanly on The AI Investor Podcast: “I’m pretty confident about 2026. I think it’s mostly in the bag at this point. The tech giants have been signaling they’ll keep growing capex next year.” Vanguard’s 2026 outlook is more cautious, warning that “U.S.-based AI scalers’ track record of growing earnings year after year will come under renewed scrutiny as they embark on unprecedented AI capital investment.” Either capex accelerates or the multiples underpinning BAI compress. There is not much middle ground.

What to Watch

Two signals, concretely: the 10-year Treasury yield holding below the 4.67% May high, and the next round of hyperscaler capex guides. If yields break out or a single mega-cap trims 2027 capex, expect BAI’s semiconductor concentration to amplify the move on the way down as easily as it did on the way up. For investors wanting AI exposure with less rate sensitivity, software-tilted peers like the iShares Expanded Tech-Software Sector ETF (NYSEARCA:IGV) offer a different profile.
