Looking for an Index fund? You may want to consider Vanguard Total Stock Market Index Investor (VTSMX Quick QuoteVTSMX - Free Report) as a possible option. While this fund is not tracked by the Zacks Mutual Fund Rank, we were able to examine other factors like performance, volatility, and cost.

History of Fund/Manager

Vanguard Group is based in Malvern, PA, and is the manager of VTSMX. Since Vanguard Total Stock Market Index Investor made its debut in April of 1992, VTSMX has garnered more than $21.63 billion in assets. The fund's current manager is a team of investment professionals.

Performance

Obviously, what investors are looking for in these funds is strong performance relative to their peers. This fund in particular has delivered a 5-year annualized total return of 14.03%, and it sits in the middle third among its category peers. If you're interested in shorter time frames, do not dismiss looking at the fund's 3 -year annualized total return of 7.84%, which places it in the middle third during this time-frame.

It is important to note that the product's returns may not reflect all its expenses. Any fees not reflected would lower the returns. Total returns do not reflect the fund's [%] sale charge. If sales charges were included, total returns would have been lower.

When looking at a fund's performance, it is also important to note the standard deviation of the returns. The lower the standard deviation, the less volatility the fund experiences. Compared to the category average of 0%, the standard deviation of VTSMX over the past three years is 17.98%. Looking at the past 5 years, the fund's standard deviation is 18.65% compared to the category average of 4%. This makes the fund more volatile than its peers over the past half-decade.

Risk Factors

Investors should note that the fund has a 5-year beta of 1.03, so it is likely going to be as volatile as the market at large. Another factor to consider is alpha, as it reflects a portfolio's performance on a risk-adjusted basis relative to a benchmark-in this case, the S&P 500. Over the past 5 years, the fund has a negative alpha of -1.09. This means that managers in this portfolio find it difficult to pick securities that generate better-than-benchmark returns.

Expenses

Costs are increasingly important for mutual fund investing, and particularly as competition heats up in this market. And all things being equal, a lower cost product will outperform its otherwise identical counterpart, so taking a closer look at these metrics is key for investors. In terms of fees, VTSMX is a no load fund. It has an expense ratio of 0.14% compared to the category average of 58%. VTSMX is actually cheaper than its peers when you consider factors like cost.

While the minimum initial investment for the product is $0, investors should also note that there is no minimum for each subsequent investment.

Fees charged by investment advisors have not been taken into considiration. Returns would be less if those were included.
