Launched on 09/09/2010, the Vanguard S&P 500 ETF (VOO) is a passively managed exchange traded fund designed to provide a broad exposure to the Large Cap Blend segment of the US equity market.

The fund is sponsored by Vanguard. It has amassed assets over $572.79 billion, making it the largest ETFs attempting to match the Large Cap Blend segment of the US equity market.

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.

Blend ETFs usually hold a mix of growth and value stocks as well as stocks that exhibit both value and growth characteristics.

Since cheaper funds tend to produce better results than more expensive funds, assuming all other factors remain equal, it is important for investors to pay attention to an ETF’s expense ratio.

Annual operating expenses for this ETF are 0.03%, making it one of the least expensive products in the space.

It has a 12-month trailing dividend yield of 1.24%.

Even though ETFs offer diversified exposure that minimizes single stock risk, investors should also look at the actual holdings inside the fund. Luckily, most ETFs are very transparent products that disclose their holdings on a daily basis.

This ETF has heaviest allocation to the Information Technology sector–about 32.40% of the portfolio. Financials and Consumer Discretionary round out the top three.

Looking at individual holdings, Apple Inc (AAPL) accounts for about 7.24% of total assets, followed by Microsoft Corp (MSFT) and Nvidia Corp (NVDA).

The top 10 holdings account for about 26.01% of total assets under management.
