SPDR Portfolio S&P 500 Growth ETF (SPYG) is an exchange-traded fund that seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of the S&P 500 Growth Index. The fund tracks an index comprising primarily large-cap growth stocks selected from the S&P 500 Index based on three growth factors, including sales growth, the ratio of earnings change to price, and momentum; eligible securities must meet liquidity and size requirements and demonstrate positive earnings in recent quarters. It holds approximately 218 equity securities, with top holdings including NVIDIA Corporation (14.34%), Microsoft Corporation (6.39%), Apple Inc. (5.66%), Broadcom Inc. (5.26%), and Meta Platforms, Inc. (5.05%), representing over 55% of assets; the portfolio emphasizes sectors such as technology services (around 30%) and electronic technology (around 29%). Launched on September 25, 2000, and issued by State Street Global Advisors, a division of State Street Corporation headquartered in Boston, Massachusetts, SPYG operates as an open-ended investment company domiciled in the United States, targeting investors seeking large-cap growth exposure primarily in North American markets. The ETF maintains a low expense ratio of 0.04%, quarterly dividend payouts (most recent ex-dividend date September 22, 2025), and has grown significantly in scale, with assets under management reaching approximately $44.14 billion as of late 2025. Recent developments include notable inflows, such as those detected in December 2025 amid market volatility, alongside annual S&P 500 style index rebalances that adjusted holdings like additions of Apple and Microsoft to growth allocations and substantial portfolio shifts in top weightings driven by strong performance in AI-related technology leaders.
