The Vanguard Intermediate-Term Corporate Bond Index Fund (Admiral Shares) (symbol VICSX) and the Vanguard Intermediate-Term Corporate Bond Index Fund ETF (symbol VCIT) are two of the largest and most popular corporate bond index funds. Some compare VICSX vs VCIT not realizing that they are just two different share classes of the same portfolio.
A quick reminder that this site does NOT provide investment recommendations.
The Short Answer
VICSX and VCIT are different share classes of the same portfolio. The decision to buy one or the other depends on investor-specific factors (some of which are listed below).
The Longer Answer
Vanguard ETFs are structured as share classes of their mutual funds. This is a patented structure that is scheduled to expire in 2023, so we may see this structure more frequently in the near future. In other words, VICSX and VCIT are not two funds pursuing an identical strategy; they are the same fund!
Historical Performance: VICSX vs VCIT
Both VICSX and VCIT were launched on November 19, 2009. Perhaps not surprisingly, performance has been identical since that time: 3.86% vs 3.88% annually. Despite changes in fees and expenses over that time period, the cumulative difference in performance over that time period is just over 40 basis points! Looking at the chart of VICSX vs VCIT below, it is obvious that they are identical.
Risks of Fixed-Income ETFs
One of the risks of fixed-income ETFs is that they trade well below their net asset value (NAV) in times of distress. This is clear if we chart VICSX vs VCIT during the first half of 2020. VCIT declined about 18% (from +5% to -13%), while VICSX “only” declined 14%. Remember, these are simply different share classes of the exact same fund! However, VCIT trades at a market price and VICSX is traded at a NAV.
This is caused by the fact that fixed-income typically trades at wide bid-ask spreads, which widen even further during market volatility. Sometimes the bids will disappear altogether. Mutual funds generally publish a NAV based on market prices (or estimated values for fixed-income), so estimating a NAV is difficult if the market freezes or bids disappear.
The consensus is that ETFs provide better “price discovery” than mutual funds, since ETFs represent actual market prices. In this example, it is widely assumed that the VCIT value was closer to value of the underlying portfolio than the VICSX NAV. Interestingly, holders of VICSX could have sold their holdings and rotated into VCIT (which is the exact same portfolio) at a substantial discount.
VCIT mostly invests in corporate bonds, which are less liquid than Treasuries. However, even funds that invest 100% in Treasuries ran into the same issue, as evidenced by looking at VBTLX vs BND.
Differences Between VICSX and VCIT
Since the two funds are actually two share classes of the same fund, I will skip the usual comparisons here. The geographic exposures, sector weights, market cap coverage so on is identical because the two funds are shares in the same portfolio. There are some resources on the internet indicating otherwise, but these are incorrect.
Factors to Consider
ETFs are free to trade at many brokers and custodians, including Vanguard. However, many brokers and custodians still charge commissions and/or transaction fees to buy/sell mutual funds. To my knowledge, Vanguard does not participate in the pay-to-play arrangements that would allow their mutual funds to trade for free on many platforms. So if an investor account is at Vanguard, it is free to trade VICSX or VCIT. However, only VCIT is free to trade in non-Vanguard accounts.
Unfortunately, Vanguard does charge a .25% fee on purchases of VICSX, no matter where the account is held. So investors should consider whether their allocation will be a one-time purchase or averaged in over time, as that may help them determined whether the mutual fund or ETF is a better choice.
There is a bid-ask spread when trading ETFs, but this spread is typically less than .01% for VCIT and individual investor trades will not generally be large enough to “move” the market. In the case of VCIT, individual investors should not have a problem trading.
Tax Efficiency & Capital Gain Distributions
ETFs are typically more tax-efficient than mutual funds, due to their ability to avoid realizing capital gains through like-kind redemptions (a process that is beyond the scope of this post). However, since Vanguard ETFs are a share class of their mutual funds, the mutual funds are able to benefit from this feature of the ETF. In other words, VCIT is able to extend its tax benefits to VICSX.
One additional consideration is that fixed-income ETFs are not quite as tax-efficient as equity ETFs. Both VICSX AND VCIT have made capital gains distributions in the past and will likely continue to do so. For instance, in 2021 both distributed an identical percentage. I noticed some posts on the internet saying that VCIT is more tax-efficient than VICSX, but this incorrect.
Tax Loss Harvesting
My personal preference is to keep a portfolio entirely mutual funds or entirely ETFs, due to the mechanics of settlement during tax loss harvesting. If an ETF has declined in value and an investor sells it, the trade and cash proceeds will not settle for two business days (T+2). That investor may want to “replace” the sold ETF immediately and attempt to buy another ETF or mutual fund simultaneously.
However, mutual funds settle on T+1 basis, so cash for the mutual purchase would be due in one business day (which is one day earlier than the cash from the ETF sale is received). This can obviously cause problems and (even though this issue can be addressed with careful planning) I find it easier to keep accounts invested in similar vehicles. In this case, if a portfolio is all mutual funds, I might lean more towards VICSX. If all ETFs, I might lean more towards VCIT.
On this topic, investors should probably avoid using these two funds as tax loss harvesting substitutes for one another since they would likely be considered “substantially identical.”
VICSX does have a stated minimum initial purchase of $3,000, so that may be a factor for some investors looking to initiate a position. The minimum purchase size for VCIT is typically one share, although fractional shares are becoming more common.
Investors can trade ETFs intraday, as well as in the pre-market and after-hours trading sessions. Investors can only buy/sell mutual funds once per day. This is not necessarily a major factor for long-term investors however.
Final Thoughts: VICSX vs VCIT
VICSX and VCIT are literally the same portfolio. However, I personally shy away from fixed-income ETFs due to their tendency to trade below NAV during episodes of extreme volatility. If two options provide the same risk and return, but one does not have periodic blowups then I’ll go with that one. Of course, there are other factors to consider (such as the above).
