@Sven, @Observant1, Sara DEVEREUX has a feature in the current Barron's. From my Summary, Part 2 (some excerpts also posted earlier by @Observant1),
Sara DEVEREUX, Vanguard Fixed-Income Head. She joined Vanguard in 2019 from Goldman Sachs/GS. After a terrible 2022, BONDS are doing better in 2023; she wears a button, “Bonds Are Back”. She thinks that the US will have a shallow recession in 2023. Inflation fell from its peak but is still high; the core PCE may be +3.3% by 2023YE, +2.xx% by 2024YE. Many supply-related issues have been resolved, but the demand has to cool to tame wages and inflation. The labor market remains strong, but it is a lagging indicator. Due to many factors now, the unemployment rate may peak at 5% in the next recession. The FED may pause in June to assess the impact of its rapid tightening so far, but rates may go up later, and may remain higher for longer. The times now are opportunities for active bond investors (remember, she is at Vanguard!). She likes portfolios of high-quality bonds of short/intermediate duration with some HY and EM (consider those as equity equivalent); munis are also attractive. HY spreads are tight, but their absolute yields are OK. She is avoiding FR/BL as those are of lower quality. Vanguard funds mentioned are VCOBX (core), VCPAX (core plus), VGIT (Treasuries – intermediate), VMSIX (multisector), VTES (short-term muni).

In this week’s Barron’s ”Up & Down Wall Street” Randall Forsyth cites 2 veteran bond traders, 89 year old Dan Fuss & Louise Yamada -
“Spoiler alert: These veterans are both cautious now, with a strong preference for short-term Treasury bills.”
Forsyth’s tune changes week-to-week, so don’t take this too seriously. But the overall tone this week, anyway, is that we’re into the early stages year of what will me a decades long rise in rates. (bear market for bonds). That supposedly explains the caution of the two veterans. It is also noted that l”Over two-plus centuries, U.S. longterm rates have oscillated around an average of 5% …”

@Hank,
I read the Barron's article you referenced.
Mr. Forsyth stated: "we thought it instructive to touch base with two market veterans who were present
at the birth of the previous long-term cycle to get their thoughts on where we might be headed."
I immediately thought of Dan Fuss before reading the next paragraph.
Anyway, Fuss and Yamada are both cautious as you have mentioned.
They are concerned about the government's finances
and suggest positioning for higher yields in the future.
Both market veterans currently prefer shorter-term Treasuries.

Hank, if you think that my system is too funny, I welcome you to dive a bit into it(link). Several did and doing very well. The whole idea is to find great risk/reward funds, small AUM is a plus, an uptrend is a must + owning only 2-3 funds.
