What gives? What am I not seeing? I would have done better just leaving my money in a money market account earning interest...analyzing on interest question only obviously share price is declining.
I’m not sure exactly what you are missing, but thought I’d point out a few things that I didn’t see mentioned. First a disclaimer – I’m not yet an advocate for buying bonds (fund or individual). They may make sense for some, but not in my situation. 2ndly, the numbers I’ll use for vfsux I gathered today 10/7 from Vanguard: distribution yield as of 9/30/22: 2.22%; yield to maturity: 4.5%; SEC yield: 4.63% (yes, it is different than ytm); average duration: 2.7 years. (on 12/31/2021 distribution yield was shown as 1.62%).
Probably the key to understanding this is understanding that the environment now is (1) rapidly rising rates & 2) high volatility. That is very different than recent past. Look closer at the metrics mentioned in that light. None of the metrics have predictive power for next month/year distribution. In a low volatility situation, they would do a better job of coming close (if you’ve used them in the past perhaps). They really can’t be used to compare different investments except for one case. SEC yield was devised due to problems using distribution yield. The SEC yield can be used to compare 2 funds at a point in time. SEC yield captured today won’t help explain performance from earlier in the year. The difference in distribution & SEC yield does give a hint for future direction. But it can’t predict future market changes.
As you likely know, when rates rise, price comes down. What you may not stop to realize is that the price change is reflected immediately. For a given bond, the coupon won’t change. But as a fund trades bonds, the different coupon may not pay out ‘immediately’. Your results may vary a good bit whether you reinvest distributions as a result.
Different points on the yield curve change at different rates. For example, look at this year & see year to date change in 3 month, 2 year, 10 year treasuries & I doubt it will be the same level of change. So yeah, in hindsight there may be investments that would have done better. Question is: is vfsux right for you going forward? I can’t answer that!
