Core Bond Funds – How to Choose One in 8 Simple Steps

 

core bond fundsSo you’ve read our article on core bond funds and are ready to choose one for yourself.  How do you choose the right fund from the thousands of available options?

 

Step 1: Passive vs. Active Core Bond Funds?

There are two types of core bond funds.  Those that are passively managed which are also referred to as “Index Funds”, and those that are actively managed.  The goal of a passively managed bond fund is to match the performance of an index as closely as possible.  The goal of an actively managed bond fund is to beat the performance of an index.

If you are not sure which type of fund is right for your situation, read our article on passive vs. active bond funds.

 

Step 2: Core Bond ETFs or Core Bond Bond Mutual Funds?

With the one big exception of PIMCO’s ETF (Ticker: BOND), the large majority of popular Bond ETFs are passively managed.  With this in mind if you want an actively managed fund you are most likely going to need to go the bond mutual fund route.

If you have decided that passively managed core bond funds are the best option read our article “Bond Mutual Funds vs. Bond ETFs” to decide whether a Bond ETF or Bond Index Mutual fund is best for your situation.

 

Step 3: Decide How Much Interest Rate Risk You Want to Take?

Generally, the longer the bonds that your core bond fund holds have until maturity, the higher the yield on the fund.  However, what you trade for that higher yield is greater volatility as interest rates change.  For how to decide how much interest rate risk you are willing to take, read our article on Bond Fund Interest Rate Risk.

 

Step 4: How Much Credit Risk do You Want to Take?

Credit risk is the likelihood that some of the bonds your core bond fund invests in will default.  The more credit risk a bond fund takes, the higher both its potential return and the volatility of those returns.  Our opinion at Learn Bonds is the potential for extra return with a mix of both government, corporate and other types of investment grade bonds is worth the extra credit risk over a government only bond fund.  The key with core bond funds is to make sure you do not stray too far out on the credit risk spectrum, such as funds that have high percentage of assets in high-yield or lower investment grade debt.

Step 5: Choose Your Category and Setup Your Screen

This step is best explained with an example.  Lets say I have gone through the steps above and decided on an Actively Managed Intermediate Term Bond Mutual Fund.  I have $10,000 to allocate to a core bond fund initially.

Now that I have picked my core bond fund category, I can create my mutual fund shortlist.  We recommend using Morningstar.com’s free mutual fund screener for this, which you will  find here.  While the screener provides many options, we will focus on a few key ones and leave the rest blank.  In this instance here are the settings we would use:

For a full explanation of each of the sections and why we choose the settings we choose, see our article on setting up a bond mutual fund screener.

 

Step 6: Create Your Shortlist

Below is a screenshot of the core bond funds that come back after we hit the show results button at the bottom of the above screen.

Two things jump out:

1. The screener returned 23 core bond funds which is way too many for a short list. We are looking for 3 to 5 funds.

2. Some funds show up in the list multiple times.  This is because of the different share classes offered by the fund.  If you don’t know what this is read our article on share classes.

A good criteria to use when you have too many 5 star rated funds (a good problem to have) is fund size.  If a fund is rated 5 stars by Morningstar and one of the biggest funds on the list,  that likely means that the funds has been vetted by more people than a smaller fund which is generally a good sign.

To do that click the “Total Assets ($Mil)” column heading all the way on the right side at the top.  This will sort the list from largest fund to smallest in terms of assets under management.  Once I do that the list looks as so:

I have highlighted the top 5 core bond funds with red boxes.  Inside the red boxes you will see different share classes of the same fund. You can identify that these are different share classes of the the same fund because of the name similarities,  and because they show the exact same amount for assets under management.  The assets under management is the total for all share classes of the same fund.

The share classes within each of the funds are going to have different fees and account minimums.  We selected $10,000 or less in our initial screen for the account opening minimum, so none of the funds on the list should require more than that.  We obviously want to pay the lowest amount possible in fees, so for the funds which have more than a single share class listed click on the names of each.  This will take you to the quote page where you can see the minimum.  Here are the screenshots for the Metropolitan West fund which has two share classes listed from our screen:

And…

I have highlighted in red where you can find the investment minimum, expense ratio, and ticker for the fund (each share class has its own ticker).  As you can see from the first screenshot above the share class with the $2500 minimum has an expense ratio of .83%.  In the second screenshot we can see that the share class with the $5000 minimum has an expense ratio of .63%.  Since we have $10,000 to invest we want to go with the second option with the lower fees, so I am going to write that ticker down.

Then I am going to repeat the process until I have the ticker for each share class of the funds highlighted above which will be my shortlist:

PTTDX
MWTRX
LIGRX.lw
WACIX
PBDDX

 

Step 7: Compare Performance

Click on the first fund in this list, which in this example is the PIMCO Total Return D PTTDX.  This will bring you to the quote page for the fund.  Click the “chart” tab at the top and then enter each of the symbols from the above list int the the “compare to symbol” box at the top of the chart.  Then click the x beside the two indexes which will be listed at the top along with the funds so it removes the performance for the two indexes and leaves just the five funds from the short list on the chart.  I have highlighted where to do this as well as what the chart looks like after following this step using the funds in this example:

Now that we see what the growth of a $10,000 investment made 10 years ago would look like there is one fund, the Loomis Sayles Investment Grade bond fund that really stands out from the pack.  Lets go to the quote page for this by entering its ticker into the quote box at the top of the page:

Loomis Sayles Investment Grade Bond A LW LIGRX.lw

What do I like about this core bond fund?

  • It was the top performer on my shortlist by a wide margin historically.
  • It has the highest yield of any fund on my list.
  • Its average Eff. Duration (interest rate risk) is on the low end for a Intermediate term fund.

Step 8: Choose My Core Bond Fund

Now that I have gone through all the funds on my shortlist I can choose my fund.  In this case I am going to eliminate 3 of the 5 funds right out of the gate.  The two PIMCO funds do not have enough information on credit risk in order for me to make an informed decision, so they are out.  The Metropolitan West Total Return is investing in below investment grade bonds.  I am looking for investment grade funds so they are out as well.  This still leaves me with two good funds to choose from however which are the Loomis Sayles Investment Grade Bond A LW LIGRX.lw and The Western Asset Core Bond FI WACIX.
These are two nice options to be left with as they are both top performing Intermediate Term Bond Funds.  However, the primary difference is clear: The Loomis Fund is taking more credit risk and more interest rate risk to generate its higher total return and yield.  As the core bond fund is meant to be an anchor fund for my portfolio there is an argument to be made for going with the “safer” Western Asset Fund.  However in this instance since the Loomis fund is still investing in investment grade bonds, and its interest rate risk is not that much higher than the Western asset fund. To me,  the extra risk is in my opinion worth the extra return.So, I have just used the Learn Bonds 8 Steps to choosing a core bond fund to choose my fund:The Loomis Sayles Investment Grade Bond A LW LIGRX.lwStill having problems choosing your core bond fund or have a question that wasn’t addressed?  Hit us up in the comments section.  For more information on bond mutual funds and ETFs visit the bond funds section here at Learn Bonds.
