JNK Vs. SJNK: Is Shorter Better?

| About: SPDR Bloomberg (JNK)


Does a lower risk/lower yield bond fund beat a higher risk/higher yield one?

I'm going to compare the SPDR Barclays High Yield Bond ETF and the SPDR Barclays Short Term High Yield Bond ETF.

I'll take a look at several risk measures as well as examine the portfolio compositions to determine which has a better risk/reward profile.

I often like to take a fund or ETF and set it next to a counterpart to see which one wins when examining their risk/reward profiles. Sometimes, two funds deliver similar returns or offer similar dividend yields or operate within the same sector or strategy but deliver their results in very different ways.

Today, I wanted to take a look at the SPDR Barclays High Yield Bond ETF (NYSEARCA:JNK) and its shorter-term counterpart, the SPDR Barclays Short Term High Yield Bond ETF (NYSEARCA:SJNK). Specifically, I wanted to pay special attention to the yields offered by the funds and the risks taken in order to achieve them. The High Yield Bond ETF should be paying the higher yield but is the additional risk taken to get that yield really worth it?


According to the ETF Database, the High Yield Bond ETF is the second largest in the space behind only the iShares iBoxx $ High Yield Corporate Bond ETF (NYSEARCA:HYG). The Short Term High Yield Bond ETF is the fourth largest.

The main thing to note in this graphic is the expense ratio. Both are identical at 0.40%, a pretty reasonable level for this type of product. The High Yield Bond ETF trades about 10 times as many shares daily as the Short Term High Yield Bond ETF, which is to be expected given their relative sizes, but liquidity is an issue for neither of these funds.

Dividend Yield

The High Yield Bond ETF has pretty consistently yielded around 70 basis points higher than the Short Term High Yield Bond ETF over the past two to three years.

The difference in yields currently is consistent with this historical spread and can reasonably be expected to continue going forward.

Portfolio Composition

While there is little overlap between the specific fixed income issues held within the funds, the fund's managers do like to target the same issuers for both funds. Bonds from Sprint (NYSE:S), Numericable Group (OTCPK:NUMCF), Reynolds (NYSE:RAI) and HCA Holdings (NYSE:HCA) appear in both portfolios.

Asset Allocation

The primary difference in the allocations of the two funds is the level of cash.

While overall portfolio risk won't be greatly impacted by the presence of cash in the portfolio, the risk level of the Short Term High Yield Bond ETF will be lower due in part to the fund's 8% cash position compared to the less than 1% allocation of the High Yield Bond ETF.

Coupon & Maturity

It might be slightly surprising to see that the Short Term High Yield Bond ETF has a greater percentage of its assets invested in securities with coupons of 6% or greater (56.3% vs. 47.5%), the fund's focus on much shorter maturities tempers the portfolio's overall risk significantly.

The fund's average maturity of 3.2 years is less than half that of the High Yield Bond ETF's 6.5 years. This contributes to a modified adjusted portfolio duration that is 45% lower than the High Yield Bond ETF (2.36 years vs. 4.33 years). The difference in credit quality of the two portfolios is substantially similar.


The two funds have performed about as would be expected since the Short Term High Yield Bond ETF's inception on March 14, 2012.

The High Yield Bond ETF has performed better overall during the four-year time frame. It outperformed during much of 2014, underperformed during the second half of 2015 as junk bond spreads started rising rapidly and subsequently outperformed again in 2016 during the market rebound.

Portfolio Risk Measures

Using two commonly used risk measures, we can examine both the beta and standard deviation of returns to determine how risky the two funds are relative to each other.

The beta measure during its infancy can be discounted a bit and where it stands right now is probably more of an accurate measure. Currently, the portfolio risk of the Short Term High Yield Bond ETF as measured by the beta is 44% lower than the High Yield Bond ETF.

Standard deviation tells a similar story. Risk levels in the junk bond market have been rising using the past three years of data. As it stands right now, the Short Term High Yield Bond ETF standard deviation is roughly 25% lower than its counterpart.

As would be expected, risk levels of the Short Term High Yield Bond ETF are lower using every measure. Modified adjusted duration is 45% lower. Beta is 44% lower. 3-year standard deviation of returns is 25% lower. While none of these is a perfect measure in and of itself, it shows that one fund is clearly less risky than the other.

Comparing the dividend yields of the two funds (5.62% vs. 6.32%), I'm looking at roughly a 12% dividend premium with the High Yield Bond ETF.

Would I give up roughly 12% in dividend income in exchange for 35%-ish less risk? I think so. I'd choose the Short Term High Yield Bond ETF in this comparison.
