This analysis unpacks the catalysts behind these trends and evaluates their implications for 2026.

The Tradr 2X Long ALAB Daily ETF (LABX) has , outperforming broader markets. This performance is tied to its 200% daily leveraged exposure to Astera Labs Inc. (ALAB), a small-cap semiconductor firm specializing in connectivity solutions for cloud and AI infrastructure according to its key statistics. , driven by demand for its NVLink-compatible products, while analysts like Stifel have dismissed concerns about its ecosystem positioning.

LABX's structure-using swap agreements to amplify returns-amplifies both gains and risks. While its October 1, 2025, price was $26.95, the ETF , 2025, suggesting volatility. However, the 17% rise likely reflects a shorter-term rebound in November-December, as the fund's price . This volatility underscores the appeal of leveraged ETFs for traders capitalizing on AI-driven semiconductor cycles.

3. Small-Cap Momentum: URTY and TQQQ Capitalize on AI and Fed Easing

Small-cap ETFs like the ProShares UltraPro Russell 2000 (URTY) and TQQQ have gained traction as Fed rate cuts and AI-driven earnings revisions boost cyclical sectors.

The Fed's projected 25-basis-point rate cut in late 2025 has further supported small-cap valuations, as lower borrowing costs reduce discount rates for high-growth companies. This dynamic is particularly relevant for ALAB and other small-cap AI enablers, which LABX and URTY amplify.
