The State Street SPDR Portfolio S&P 500 ETF (SPYM) was launched on November 8, 2005, and is a passively managed exchange traded fund designed to offer broad exposure to the Large Cap Blend segment of the US equity market.
The fund is sponsored by State Street Investment Management. It has amassed assets over $149.17 billion, making it one of the largest ETFs attempting to match the Large Cap Blend segment of the US equity market.
Why Large Cap Blend
Large cap companies typically have a market capitalization above $10 billion. They tend to be stable companies with predictable cash flows and are usually less volatile than mid and small cap companies.
Typically holding a combination of both growth and value stocks, blend ETFs also demonstrate qualities seen in value and growth investments.
Costs
When considering an ETF's total return, expense ratios are an important factor, and cheaper funds can significantly outperform their more expensive counterparts in the long term if all other factors remain equal.
Annual operating expenses for this ETF are 0.02%, making it one of the least expensive products in the space.
It has a 12-month trailing dividend yield of 0.99%.
Sector Exposure and Top Holdings
ETFs offer a diversified exposure and thus minimize single stock risk but it is still important to delve into a fund's holdings before investing. Most ETFs are very transparent products and many disclose their holdings on a daily basis.
This ETF has heaviest allocation to the Information Technology sector -- about 39.5% of the portfolio. Financials and Telecom round out the top three.
Looking at individual holdings, Nvidia Corp (NVDA) accounts for about 7.61% of total assets, followed by Apple Inc (AAPL) and Microsoft Corp (MSFT).
The top 10 holdings account for about 36.69% of total assets under management.
Performance and Risk
SPYM seeks to match the performance of the S&P 500 INDEX before fees and expenses. The S&P 500 Index is designed to measure the performance of the large-capitalization segment of the U.S. equity market.

The ETF has a beta of 1.00 and standard deviation of 107.89% for the trailing three-year period. With about 508 holdings, it effectively diversifies company-specific risk.
