PBCay One RSC Ltd

PBCay One RSC Ltd's Q1 2026 13F is a $1.34B, 18-position portfolio that more than doubled AUM from $567.2M in Q4 2025 to $1.34B in Q1 2026 (+$777.4M, +137%) via eight simultaneous new opens and dramatic increases in core holdings. SPDR S&P 500 ETF (SPY, $410M, 30.5%, NEW) became the portfolio's largest position overnight at full institutional size -- the defining structural move. The technology core expanded dramatically: Taiwan Semi (+13,094% shares, +$80.7M), Alphabet (+922% shares, +$59.1M), NVIDIA (+65.7% shares, +$35.2M), MercadoLibre (+136.9% shares, +$34.0M), Amazon (+28.0% shares, +$13.2M), Microsoft (+10.1% shares), and S&P Global (+18.6% shares). Sherwin-Williams was the only major decrease (-26.4%, -$25.1M) and TransUnion was the sole liquidation (SOLD). Eight new positions (SPY, FXI, Meta, Danaher, Eli Lilly, Thermo Fisher, UnitedHealth, GE Vernova) transformed the portfolio from a concentrated 11-position tech-and-consumer book into a broadly diversified 18-position quality-plus-AI allocation. The iShares Bitcoin Trust position was reduced (-20.6%) as crypto volatility persisted. The sector breakdown now spans ETF (35.4%), Technology (27.0%), Healthcare (9.8%), Communication Services (8.9%), Consumer Cyclical (12.3%), Unknown (5.6%), and Financial Services (1.0%). The 76.50 whaleScore on $1.34B reflects AUM. The portfolio's post-Q1 identity is a core-satellite structure with SPY as the 30.5% beta core and AI-and-quality names (NVDA, TSM, MSFT, AMZN, GOOGL, META, DHR, LLY, TMO) as high-conviction satellites -- a genuine diversification from the prior concentrated mandate.
