What is this fund?
SMID CAP FUND is Fidelity's way of saying SMALL to MID CAP FUND.  Small to Medium is self explanatory.  Cap is capitalization, and it basically means how much the sum of all the existing shares of the company are worth.  Fidelity names the funds inside their 401k plans according to who provides the fund.  They also provide management resources for funds chosen by your employer. There should be more available about the fund you're interested in on your Fidelity 401(k) site.
"You seem to be assuming that ETFs must all work like the more traditional closed-end funds, where the market price per share tends—based on supply and demand—to significantly deviate from the underlying net asset value per share. The assumption is simplistic. What are traditionally referred to as closed-end funds (CEFs), where unit creation and redemption are very tightly controlled, have been around for a long time, and yes, they do often trade at a premium or discount to NAV because the quantity is inflexible. Yet, what is generally meant when the label ""ETF"" is used (despite CEFs also being both ""exchange-traded"" and ""funds"") are those securities which are not just exchange-traded, and funds, but also typically have two specific characteristics: (a) that they are based on some published index, and (b) that a mechanism exists for shares to be created or redeemed by large market participants. These characteristics facilitate efficient pricing through arbitrage. Essentially, when large market participants notice the price of an ETF diverging from the value of the shares held by the fund, new units of the ETF can get created or redeemed in bulk. The divergence quickly narrows as these participants buy or sell ETF units to capture the difference. So, the persistent premium (sometimes dear) or discount (sometimes deep) one can easily witness in the CEF universe tend not to occur with the typical ETF. Much of the time, prices for ETFs will tend to be very close to their net asset value. However, it isn't always the case, so proceed with some caution anyway. Both CEF and ETF providers generally publish information about their funds online. You will want to find out what is the underlying Net Asset Value (NAV) per share, and then you can determine if the market price trades at a premium or a discount to NAV. Assuming little difference in an ETF's price vs. its NAV, the more interesting question to ask about an ETF then becomes whether the NAV itself is a bargain, or not. That means you'll need to be more concerned with what stocks are in the index the fund tracks, and whether those stocks are a bargain, or not, at their current prices. i.e. The ETF is a basket, so look at each thing in the basket. Of course, most people buy ETFs because they don't want to do this kind of analysis and are happy with market average returns. Even so, sector-based ETFs are often used by traders to buy (or sell) entire sectors that may be undervalued (or overvalued)." "First, consider what causes taxes to apply to a mutual fund, index or actively managed.  Dividends and capital gains are generally what will be distributed to shareholders given the nature of a mutual fund since the fund itself doesn't pay taxes.  For funds held in IRAs or other tax-advantaged accounts, this isn't a concern and thus people may not have this concern for those situations which can account for a lot of investing situations as people may have 401(k)s and IRAs that hold their investments rather than taxable accounts. Second, there can be tax-managed funds so there can be cases where a fund is managed with taxes in mind that is worth noting here as what is referenced is a ""Dummies"" link that is making a generalization.  For taxable accounts, it may make more sense to have a tax-managed fund rather than an index fund though I'd also argue to be careful of asset allocation as to maintain a purity of style can require selling of stocks that grow too big and thus trigger capital gains,e.g. small-cap and mid-cap funds that can't hold onto the winners as they would become mid-cap and large-cap instead of representing the proper asset class. A FUND THAT PLAYED IT SAFE--AND WAS SORRY would be a Businessweek story from 1998 of an actively managed fund that went mostly to cash and missed the rise of the stock market at that time if you want a specific example of what an actively managed fund can do that an index fund often cannot do.  The index fund is to track the index and stay nearly all invested all the time." "A mutual fund's return or yield has nothing to do with what you receive from the mutual fund. The annual percentage return is simply the percentage increase (or decrease!) of the value of one share of the mutual fund from January 1 till December 31. The cash value of any distributions (dividend income, short-term capital gains,  long-term capital gains) might be reported separately or might be included in the annual return.  What you receive from the mutual fund is the distributions which you have the option of taking in cash (and spending on whatever you like, or investing elsewhere) or of re-investing into the fund without ever actually touching the money. Regardless of whether you take a distribution as cash or re-invest it in the mutual fund, that amount is taxable income in most jurisdictions. In the US, long-term capital gains are taxed at different (lower) rates than ordinary income, and I believe that long-term capital gains from mutual funds are not taxed at all in India. You are not taxed on the increase in the value of your investment caused by an increase in the share price over the year nor do you get deduct the ""loss"" if the share price declined over the year. It is only when you sell the mutual fund shares (back to the mutual fund company) that you have to pay taxes on the capital gains (if you sold for a higher price) or deduct the capital loss (if you sold for a lower price) than the purchase price of the shares. Be aware that different shares in the sale might have different purchase prices because they were bought at different times, and thus have different gains and losses.  So, how do you calculate your personal return from the mutual fund investment? If you have a money management program or a spreadsheet program, it can calculate your return for you. If you have online access to your mutual fund account on its website, it will most likely have a tool called something like ""Personal rate of return"" and this will provide you with the same calculations without your having to type in all the data by hand. Finally, If you want to do it personally by hand, I am sure that someone will soon post an answer writing out the gory details." Toward the philosophical side of your question, it seems to me that what is most important is knowing how well your fund is performing versus it's benchmark. This is an actionable piece of information that can help you get out of an under-performing fund, although if you're already using Vanguard it's likely a low cost and broadly diversified fund. Ultimately, what you want to avoid over the long term is under-performing the market due to high fees, market timing, poor fund selection etc., and selecting a fund that closely tracks the market seems to be the best way to achieve this, assuming that you intend to be a passive investor. I don't see a clear benefit to calculating a personal rate of return. If the fund is performing well versus its benchmark, you are likely to stay with it, and if it is performing poorly, you  are likely to pull out. At the end of the day, the complicated accounting won't actually change the amount you've got in your account, so I'd recommend picking a good fund, checking up on it once in a great while, and putting your time to better purpose. "You have many alternatives to the funds you mentioned. It is actually very unusual for ETFs to have such high denominations. Possible alternative: iShares IVV What would you recommend I do with $1000? A diversified index fund is a great equity investment for the long run but might be considered ""boring"" by newcomers who think of equity markets as something more exciting. Maybe add a share or two, small ones, just to show the differences to the fund. This wouldn't be called wise investing but it certainly would have an educational effect. Except if this money is all you saved for your daughter, then don't gamble any of it." "Lindsell Train Investment Trust could be different than the ""Lindsell Train Limited"", the company that runs the fund and thus you are mixing apples and oranges here since the bank isn't a listed stock." It is very likely that the fund paid out a dividend in the form of reinvested shares.  This happens with many funds, especially as we come to the end of the year. Here's a simplified example of how it works.  Assume you invested $1000 and bought 100 units at $10/unit.  Ignoring the daily price fluctuations, if the fund paid out a 20% dividend, you would get $200 and the unit price would drop to $8/unit.  Assuming you chose to reinvest your dividends, you would automatically purchase another $200 worth of units at the new price (so 25 more units).  You would now have 125 units @ $8/unit = $1000 invested. In your example, notice that you now have more shares than you originally purchased, but that the price dropped significantly.  Your market value is above what you originally invested, so there was probably also a bit of a price increase for the day.  You should see the dividend transaction listed somewhere in your account. Just to confirm, I did a quick search on ICENX and found that they did indeed pay a dividend yesterday. No, some of Vanguard's funds are index funds like their Total Stock Market Index and 500 Index. In contrast, there are funds like Vanguard PRIMECAP and Vanguard Wellington that are actively managed. There are index funds in both open-end and exchange-traded formats. VTI is the ticker for Vanguard's Total Stock Market ETF while VTSMX is an open-end mutual fund format. VOO would be the S & P 500 ETF ticker while VFINX is one of the open-end mutual fund tickers, where VIIIX has a really low expense ratio but a pretty stiff minimum to my mind. As a general note, open-end mutual funds will generally have a 5 letter ticker ending in X while an ETF will generally be shorter at 3 or 4 letters in length.
