@msf, I got my numbers from charting on 'StockCharts by just moving the bar 30, 90, 180 days and taking the 3/1 value. But as noted, the numbers are just a non-exact reference for comparison to a 1 year treasury. I think a better comparison than looking at just a given months yield.

The figures are old, e.g. M* reports a 1 month return (as of March 1) of 0.27%. Confirmed by RiverPark, whose page shows month return ending 2/28 as 0.27%. M* chart shows a return of 0.418% for 12/30/22 through 1/30/23.
All of this just confirms your writing that "extrapolating the data is anything but exact", and my common refrain that "what have you done for me lately" (here, the past month) distorts analyses.
Feb returns were unspectacular because rates were rising quickly, depressing the prices of holdings (even very short term ones). Thus one sees the occasional daily decline in RPHYX in Feb, but no decline in January or last December. This is why RPHYX/ RPHIX should hold its own unless there are more rapid rate increases. Outperform is more iffy.

I go back and forth on this fund versus treasuries now in the 4.7-5% range, but RPHYX has actually had a relatively good run the past 6 months.
What I see for total return over that time:
180 days +3.3% extrapolated 1 year return 6.6%
90 days +2.11% extrapolate 1 year return 8.4%
60 days +1.13% extrapolate 1 year return 6.8%
30 days +.41% extrapolate 1 year return 4.9%
Extrapolating the data is anything but exact, but I think it gives a closer idea than yield for where it's headed in comparison to other fixed income, like treasuries. Maybe I'm wrong on that. That said, this fund was the bulk of my withdrawal bucket for quite a while, but I have reduced it substantially the past couple months to buy treasuries.

I prefer to look at total return. If we're looking at payout rates, the payout rate of T-bills is 0.00% (zero coupon). At this point, 6 month T-bills come out a bit better.
Annualized total return of RPHIX extrapolating from YTD (Jan &Feb, 59 days) of 0.72% comes out to about 4.53% with daily compounding. In a modestly rising interest rate environment I expect a slightly better return - with high turnover (164%), reinvestments should fetch a bit higher yield.
Projected yield on next auction of 6 month T-bills is 4.9%. Duration is 6 months (for zero coupon bonds, duration = maturity). Even if rates rise 3/4% in the next half year and one needs to liquidate, one should be able to get at least:
4.9% - 1/2 year x 3/4% = 4.525%
So in theory at least, one will get a somewhat better return with T-bills if held to maturity and will be risking very little if one sells early (mimicking the liquidity of RPHIX).
Pretty close to a wash (aside from state income tax concerns) - one might think of RPHIX as a hold. New cash? I would go with the T-bills.

Interesting he thinks energy is expensive although most oil stocks are trading at PE etc well below the SP500 and energy still makes up a tiny % of SP500

I understand your sentiments @sma3, but I think we also have to look at:
1) TTM P/E vs forward P/E (trailing measures include some flush and warnings due to higher energy prices in ‘22)
2) Energy stocks generally always have low P/E’s, especially in relation to the overall market (S&P 500, etc.)
Not a criticism….I do the same….also, I didn’t read the annual report yet, but I imagine he is saying defensive stocks (safer during recession risks and higher volatility) and commodities (inflation trades) are “played out.”

It's not just this Hartford fund that Wellington manages.
"Hartford Funds offers a diverse line-up of mutual funds, primarily sub-advised by Wellington Management."

2001, WSJ: Behind the Scenes: Wellington Management Quietly Puts Hartford Funds Group on Map
https://www.wsj.com/articles/SB997055055405588489
From 2012, Pensions and Investments: "Wellington currently subadvises 45 of the Hartford's 77 mutual funds, including all of the equity funds. But The Hartford is in the process of moving all of its funds to Wellington, pending approval from the remaining funds' board of directors."
https://www.pionline.com/article/20120330/ONLINE/120339999/the-hartford-moves-closer-to-wellington-looks-to-pump-up-its-mutual-funds
From M*: "Wellington has long run the firm's equity funds--over half of its $116 billion in fund assets--and took the reins of Hartford Fund's fixed-income platform beginning in 2012. In 2016, Hartford Funds ... partnered with U.K.-based Schroders to expand its investment platform further."
https://www.morningstar.com/asset-management-companies/hartford-funds-BN00000J6S
A lengthy, current (Feb 23, 2023) piece (book excerpt) on Wellington's organization, history and relationship to Vanguard (and others):

The third component of Wellington’s strategy would be a group of unusually capable senior relationship managers, superior to what other competitors could offer. These professionals would “belong” to each of their clients’ senior executives and would custom tailor an optimal portfolio of specialist portfolio managers.
...
They created a diverse portfolio of investment units that could be custom-blended to suit each major client and, most particularly, Wellington’s largest client: Vanguard.

https://www.institutionalinvestor.com/article/b8xk7ncyw2d0pz/The-Inside-Story-of-How-Wellington-and-Vanguard-Became-Partners
Hartford is a relatively unheralded place to find funds managed by Wellington. If Vanguard/Wellington doesn't have a particular type of fund one is interested in, one might look for that type of fund at Hartford. These days, their A shares are widely available NTF, and their less expensive Y or I class shares are available TF with low mins. Of course, when offered in ETF form, those funds are pretty much universally available.

1. Noted that GE, Amazon and Microsoft were sold and bought (Amazon and Microsoft).
2. Treasury notes was increased to 9%. Recall it was at 6-7% in the semiannual report.
3. Asset allocation: 62% stocks, 32% bonds, and 6% cash. In the past, the fund has over 70% stocks.

Jason Zweig had an article in WSJ describing what @hank wrote above. It is about making lemonade out of lemon from treasuries.

Until last year, the Fed had kept interest rates near zero for most of the past decade-and-a-half. Investors became desperate for something, anything, that yielded more than 1%. Wall Street spewed forth high-yield debt, energy partnerships, emerging-market bonds, private credit funds, private real-estate trusts, business-development companies, floating-rate bank-loan funds—all sold on the premise that you needed to take extra risk (and pay extra fees) to get extra income.
But a 5% yield on short-term Treasurys is like kryptonite for the purveyors of that propaganda. “Why chase yield if you’re getting decent returns on a diversified, high-quality fixed-income portfolio?” says Julie Virta, a senior financial adviser at Vanguard Personal Advisor Services in Malvern, Pa.

https://wsj.com/articles/welcome-to-the-5-world-where-yield-chases-you-af3df384
At 4% treasury yield, how does that compete with stocks in general? In just 2 months, the 60/40 portfolio has rollbacked all the gain since the beginning of this year.

(Quoting from above:)
"Utilities over staples—"
I've been bird-dogging UTILITIES for quite a while. I have not been able to find one whose P/E was not too high for my liking. Or else the dividend was too low or missing altogether.
Just checked-up on FORTIS again, out of St. John's, Newfoundland. (FTS.) The P/E is still way up there, at 19.31. The div. looks attractive, though. And using the chart, I see it hit an all-time high on 31 May, 2022. Tonight, it's down from that peak by -18.27%. Maybe someone ELSE will be tempted to buy.

4.02% on the 10-year Wednesday evening. Good grief. It’s getting harder to make $$ in these markets,

Going, going, gone?
There is news that Silvergate/SI delayed filing reports with the SEC and raised going-concern issues. It seems that it had to suddenly pay back the large FHLB loan (why it got that loan in the first place was my question then; didn't seem like housing related). It is below $10 in the after-markets this evening. Some are speculating on Twitter if it would survive this weekend.

thanks so much for letting us know this report was out. I was intrigued by Giroux's discussion of both NXPI and TXN back in the Fall so did some more research and bought both. They have done well. I track his monthly holdings and there's a new stock that has popped up in his top 10 -- Intercontinental Exchange. Not familiar with that company but will read up.

In addition to the 10 yr yield, the 2yr treasury yield reached 4.8% on Tuesday (a level last seen in mid-2006). The 6 month T bill reached 5.1%. Stocks continue to fall today.
Pimco managers have been buying long treasuries as their prices dropped with increased yield.

The bonds were still in my Mom's name. We thought about changing that while she was still alive, but it would have required us all to go to bank and do the same thing and she didn't have the stamina for it at 99.
I don't remember if we could have done it by mailing in the bonds etc, but as you point out, that requires trip to PO and insurance and certification. I love my lost PO staff, but I do not trust the USPS to handle things with 100% efficiency. They lost my daughter's college tuition check. Almost got kicked out of school!

Amazingly (to me, at least), it seems that even with power of attorney one cannot change the title on a savings bond.
https://www.treasurydirect.gov/forms/sav0105.pdf
What confused me was that the way you wrote your original post, it sounded like all siblings had to be at the bank together to cash the savings bonds. However, each bond could have been cashed alone by the individual sibling named as beneficiary on that bond. Three trips and six hours instead of one trip and two hours; not really an improvement.
Your experience illustrates the variability in cashing savings bonds in banks. I recently helped (instructed) someone in cashing inherited savings bonds. This person's main bank was Capital One, which is how I learned that Capital One doesn't handle savings bonds. A backup bank initially informed this person that the money would have to be left in an account at the bank for some number of days, or perhaps it was weeks. Fortunately, when they actually cashed the inherited bonds, it was a quick and painless process, and the cash was made available either immediately or within a day (I forget).
Regarding postal services: while registered mail gets somewhat more careful handling, ISTM its main virtue is insuring valuables. Nonnegotiable instruments like checks and savings bonds have no insurance value. So I don't use registered mail for them.
https://faq.usps.com/s/article/Registered-Mail-The-Basics
I use certified mail when I want proof of delivery (e.g. for a legal notice). Even certified mail can get lost (been there, done that). Maybe certified improves your odds of completed delivery, but there's still a risk. If TD says it didn't receive the savings bonds, all the proof in the world to the contrary won't help avoid filing for replacements.

I am on Mark's side. I am still a paper addict, but think it is wise not to have to through out 14 full newspapers (NYT and WaPo) a week in addition to three or four slick magazines.
Reading online is not the same to me as on paper.
A large part of this is the way newspapers in particular have "dumbed down" the online versions. The Washington Post fortunately still has the print edition duplicated online.
A much different experience to me

The 10y T touched 4% earlier today. Just for reference, Pimco's base case range from their January outlook was 3.25-4.25.
