Another consideration is how frequently an investor intends to trade. Many mutual funds discourage or forbid in and out trades to the same fund within a 30-day period. There is no such time barrier with ETFs.

Howard from CA posted over 6 years ago:

Is there a screener that allows you to compare mutualfunds to ETFs?

Charles from IL posted over 6 years ago:

Howard, I have not seen one. While admittedly not a perfect a solution, you could download the spreadsheet for our mutual fund guide and our ETF guide to compare funds in similar categories. All of our guides are can be found at -Charles Rotblut

Israel from NY posted over 6 years ago:

etfs are less expensive, and some brokerags do not charge commission.

Robert from MD posted over 6 years ago:

Howard, use, select Research then mutual funds, select any Fidelity mutual and on that page you can compare any combination of four other mutual and/or ETFs.

Mark b. from NH posted over 6 years ago:

Vanguard offers the same service.

Charles, your columns and monthly messages are excellent. A great new addition. Thanks.

Ken from CA posted over 6 years ago:

ETFs allow you to check the price during the day, and to place limit orders or to trade during the day. That way you can know the price which you pay or price which you get. With mutual funds you don't know the price during the day and have to put in an order ahead of closing and get the closing price which is unknown when the order is placed.

Vanguard has several ETFs the are the same as their mutual funds, so with those you can choose either a mutual fund or ETF and get the same investment.

Anthony from NY posted over 6 years ago:

Is there a mutual fund or ETF composed solely of other ETFs so that you can obtain a portfolio of various investing strategies or allocation theories by investing in only one ETF?

Yefim from CA posted over 6 years ago:

Yes, check the UNBOX fund in the Morning Star. This is FUNDX ETF Aggressive Upgrader that consis solely of othe ETFs.

Habeeb from MI posted over 6 years ago:

What about tax implications? I have to pay significant taxes on LT distributions for Vanguard Energy Fund even though I didn't buy or sell any shares - I've been thinking of switching over my portfolio to ETFs.

Charles from IL posted over 6 years ago:

Habeeb-The tax implications depend on how the fund is managed. Both our Mutual Fund and ETF guide show how tax efficient each fund is. -Charles Rotblut, AAII

Mark, thanks for the kind words. -Charles Rotblut, AAII

Roy from CA posted over 6 years ago:

You did not mention that ETFs can trade at a discount or premium to their net asset value. How big a problem is that, particulary if they are at a discount when you want to sell?

Also, ETFs are supposed to be more tax efficient because they don't have to sell shares to meet redemptions. I do not know from real world experience how much difference that makes, particularly as compared to large funds that have cash reserves to handle redemptions.

Howard from CA posted over 6 years ago:

Thanks all for your help comparing ETFs with mutual funds.I tried Fidelity using both their ETF screen and their mutual fund screen but they don't include any data other than the NAV. Vanguard does allow you to compare ETFs and Mutual funds both theirs and other ETFs and mutual funds but the depth of their info is less than Fidelity's so I think you need to use both. Thanks again for your input.

John from VA posted over 6 years ago:

Has anyone compared the bottom line cost of trading ETF's versus individual stocks? I am looking at my first ETF buy, considering PIMCO TRXT available starting 3/1/12. Schwab charges $8.xx per stock trade. Will the fund costs be prorated and deducted from the net sale amount?


IOD from CA posted over 6 years ago:

I find Charles and Mark B.'s comments most instructive. Yes, you don't have as much strike price control with a mutual fund, but have to check to make sure you are choosing the right strike price when buying or selling an ETF, because NAV may be over or under-priced with ETFs.

In the end, I wish I had created my company's 401k plan with a company that allows ETFs within the 401k plan. Instead I went with Vanguard, which has some good mutual funds, but is not giving me the granular diversification I could get with ETFs. Vanguard has ETFs, but they can't be purchased in the 401k, only within the IRA or non-retirement brokerage accounts.

Alex from CA posted over 6 years ago:

Indigo, my employer's 401k is with Vanguard, and I had no problems placing most of the account's worth in a Vanguard's "brokerage window" where I can trade stocks and ETFs to my heart's content (on most of them, but not all, I can also choose commission-free, fractional-shares automatic dividend reinvestment). [I do also keep a few Vanguard mutual funds there, and those are where my monthly contributions and my employer's matching thereof automatically go every month].

Also, for at least some number of trades per month on the "brokerage window" (far more than I need, I don't trade very actively at all there), I pay a wonderful commission of just $2.

I imagine it's just a question of negotiating with Vanguard exactly what is going to be allowed to employees in the 401k and at what cost -- my employer is a large, financially savvy company with a well-deserved reputation for looking after employees, so I guess they had both the negotiating leverage and motivation to haggle;-).

El from IL posted over 6 years ago:

I use indexed ETF's as core holdings and switched most of my mutual fund holdings in my taxable account to ETF's a few years ago. I got tired of actively managed MF year end short term (taxed as ordinary income) and long term (taxed as capital gains) distributions, especially when they lost value in 2000. Many were surprises with little warning or planning time.

With actively managed MF's I also checked Portfolio Turnover, the % of the MF holdings sold annually. The higher that number the more likely distributions would be short term. Now with ETF's I control what price I pay, what price I sell at, when I take gains or losses and their yield from dividends. Yes, NAV comes into play but since they are core holdings I plan to keep them for a longer time period which negates much of that problem.

Like indexed MF's, currently there is a wide variety of indexed ETF's that should satisfy most of your needs.

Something I didn't see discussed was the advantage of options on ETF's. The August 2010 issue had an article entitled "The Covered Call: An Income-Generating Options Strategy"

PG from NY posted over 6 years ago:

I've started using to get another angle on my 401K and IRA holdings. I don't rely on its advice 100%, but it's a good sanity check to use for confirming the results of other screeners. It's a fairly new web site (started in Oct. I think), but they're off to a good start from what I can see so far. Very user-friendly and slick-looking. I'd love to see AAII do a review of jemstep sometime!

Richard from CT posted over 6 years ago:

I have found the only time it makes sense to buy actively managed mutual funds is when they meet the following criteria: Low load, current manager for at least five years,low turnover,fund manager a major investor in his own funds,clear & understandable investment strategy and evidence it is followed,close the fund to new investors when there are not enough opportunities to profitably follow the stated investment strategy,acheived significantly better performance than its benchmark for the last five to ten years at a atandard deviation no greater than the benchmark and heavily weight how the fund did during the most recent major decline in the stock market. If you cannot find funds meeting these criteria go buy the ETF/ETFs that mirrors the index t6hat meets your need.

Sharon from NJ posted over 6 years ago:

I'm some what of a passive investor. I use mutual funds, because they allows me to automate purchasing new shares as I put more money in my brokerage account. With ETFs, I have to purchase manually.

Jim from CT posted over 6 years ago:


If you want a "fund" of ETFs you should look at Fidelity's Portfolio Builder tool found under the Research>ETF tabs on the account page.

It allows you to enter an number of ETFs, set allocation by dollar amount or % of investment and then save the "basket" for trading. If you make a basket you can purchase the basket as a group. This might simplify dollar cost averaging into a diversified group of ETFs.

I have not used the feature yet but I am considering a test drive.

Robert from WI posted over 3 years ago:

In a taxable non qualified account ETFs may have the advantage because capital gains are not paid until the ETF is sold, unlike MFs that distribute gains continually, and have capital gains taxes that have to be paid annually. No advantage regarding dividends.

Vaidy Bala from AB posted over 2 years ago:

With many, many choices ETFs offer diversity and advantages, especially low fees compared to MF. Several academic studies have proven this fact. Within few days are also cashable. In my 11 years of ETF experience, I certainly say, it is worth it as a a private retired individual investor.

Frank Hopler from FL posted over 2 years ago:

You do not mention performance; my experience following mutual funds and ETFs in comparable categories suggests very few mutual funds actually beat their comparable index over a given period.

Harry Rich from OH posted over 2 years ago:

My experience with ETF's, which may not generalize, is that when there's a matching index fund 10K+ in the index fund will often get me a share class with an expense ratio matching that of the ETF. This means that if I buy ETF's rather than the funds I have to, on average, find enough of a trading advantage to cover the bid-ask spread on the ETF's. I suspect that my actual trading advantage is close to zero, so, even when there is a difference in expense ratio the holding period to cover the spread can easily go into years. I can see no alternative to doing the math in each case.

I have used ETF's to diversify when the corresponding fund minimum would be too large for my portfolio, and to take speculative positions on market sectors.
