IMHO, this is the best "cash" option available today if your holding period is at least one year.
However, you can only purchase $10K of I-Bonds per year (additional $5K possible using tax refund).

The $10k limit is per individual/account. Spouses can buy an additional $10k. If you have a business (LLC, partnership, self-employment), you can set up an entity account that can purchase another $10K.

Taxes apply when redeemed
Just one tax - federal. Savings bonds, like Treasuries, are exempt from state and local taxes. Making their rates look even better.

If it’s more beneficial, you can pay taxes annually as the interest accrues.

Standpoint always has 50% invested in equity ETFs but they can use futures contracts to change that exposure. In summer, when we spoke, that were at 65% net exposure. The futures sleeve has position triggers at 3/6/9 months, I believe. A three month equity downtrend triggers some short, six months triggers more ... that sort of thing. Nominally they could go down to zero but that's not the intend.

I believe the reason REMIX/BLNDX did well during the downturn is it shorted oil, which collapsed in 2020. I also believe it always has at least 50% exposure to stocks. Not positive about this, but if that's true, it should produce decent returns during bull markets, yet be less defensive normally than futures funds that aren't perpetually long stocks in bear markets.

Came across this elsewhere. Thought I’d pass it along.
Story on I Bonds
READ the conditions. The rate is guaranteed only for the first 6 months before it resets. Must keep for 1 year. 3 months penalty if redeemed in under 5 years. Taxes apply when redeemed.

By the way, three of the funds in registration are metaversary. One is literally the Metaverse ETF. One is the Clockwise ETF which urges us to embrace “5G enabled opportunistic investing,” which “focuses on the meaning of time.” The Green Alpha ETF invests in companies solving "major systemic risks including, but not limited to climate change, resource degradation and scarcity, and widening inequality and the resulting erosion of social cohesion." The Erosion of Social Cohesion Fund. Has a ring to it.

reserving the right to reject orders exceeding ...
You were given imprecise information. Fidelity, like most fund sponsors, puts in boilerplate allowing them to reject any purchase, including a purchase via an exchange if they feel it would disrupt the fund. But not sell orders. If they did, the funds would no longer be classified as OEFs.

An open-end fund is required by law to redeem its securities on demand

https://www.sec.gov/rules/proposed/2015/33-9922.pdf
Based on the purchase dollar limit you were given for FCNTX, and the limit that I actually hit on a very new and very small Fidelity fund, it looks like Fidelity sets its fund limits at 0.1% of AUM. (M* shows FCNTX as having $139.5B, or roughly 1,000x the purchase limit.)
Regarding redemption in-kind, Fidelity (or any fund company) would distribute securities owned by the fund. Obviously if the fund were to sell some securities just to purchase other ones to hand you, it might as well hand you the cash since that would be no more disruptive.
...
According to the latest semiannual statement, Fidelity Contra redeemed 293,065 FCNKX shares in kind, worth $5,071.454. It does happen.

'Imprecise', well, sort of. It does appear to be an online issue and an editing problem, said the editor. (No one has said anything at any point about purchases.)
Today's trade-block message says
(009073) The order you have entered exceeds the dollar amount that may be traded in the mutual fund as specified in the prospectus. Please review your order or call a Fidelity representative at 1-800-544-6666.
So I used chat to talk w a rep who researched and then reported
Purchases, exchanges, or redemption cannot exceed $500,000 per day. Anything over that requires a call in request which will even need approval from someone higher up than me.
to which I said 'So the text does not exactly mean what it says; I suggest a change to yada-yada "greater than $500k cannot be accomplished online but require human approval ..." and he said he would so note that and escalate it. We'll see. I cited the SEC footnote.
Plus I sent email just to get something more official in writing.

To buy a house costs more, but to rent an apartment in a big covid-wracked city costs less than before the pandemic in many cases:

Our state (MI) sets spirit prices for some weird reason. Retailers can charge more if want - but rarely do. Overall, Scotch hasn’t moved much over past several years. One of the better values is Dewars 12-Year at $30 - a noticeable cut above their popular White Label. JW Black, a favorite of mine, runs $40 - occasionally $2 less. Aberfeldy (single malt) at $40 is the best buy going IMHO.
Services seem to be where the prices have risen the most. Noticed big jump picking up a few shirts I had laundered recently. As I remarked on another thread, there’s a 2-3 week wait in our area for car / truck repair. A $335 bill for replacing a front wheel bearing on my pickup nearly knocked me over. But when I checked online, the price was right in the ballpark.

Thanks for mentioning; I hadn't looked in a while. How about NEAIX? You'd have to be convinced about tech, though!

NEAIX is more growthy and multi-cap (it’s about evenly split between large, mid, and small caps) than I’m looking for. Has a higher max drawdown and lower upside/downside ratio.

MSSMX and NESGX are the two Fido NTF SCG funds that always end up being my final two funds to select from after screening that cat.
NESGX is more expensive, less volatile and similar TRs over standard interim periods, and a very worthy candidate in this cat.

The institutional class, NESIX, has a lower ER than MSSMX and Schwab only requires a minimum investment of $2500/$1000 with a TF. (Fido, unfortunately, has a $100K minimum.)

Nobody needs to know all the stuff they want to know. Whenever I'm required to give an email address on a web-form in order to proceed--- that's why I have a spam email address with false EVERYTHING in it. False name, gender, address, planet. I like to have some fun with it, often. Address? Same as Elwood Blues: 1060 W. Addison.

Thanks, David, for pointing out REMIX / BLNDX in the NOVEMBER Commentary. I used to have it on my watchlist, but apparently it had fallen off. Held up real nice in March 2020 (MAX DD of -9.3%).
Managed futures (50% of the fund) are usually a bit of a black hole in my mind, but at least "The positions can be in stocks and fixed income, as well as currencies and commodities."
If REMIX can provide annual returns somewhat similar to FMSDX, but with better downside protection, then it could be a find.

For example PRPFX which appears to have closed up .68% at $50.59. M* last check had it at Friday’s lower close. Just a heads-up.

I've looked into this fund as a domestic micro-cap growth fund as I don't need another small-cap growth fund.
http://portfolios.morningstar.com/fund/summary?t=NESGX&region=usa&culture=en-US
M* has given it five stars. It has been a top quarterly performer in the WSJ at least on one occasion that I can remember (one was the April 5, 2020 edition, "Hanging In: Stock Funds’ No. 1 Manager Gained 12.8%." There may have been a couple of other occasions, but I can neither find nor remember.
If you don't have a small cap growth fund, this may be a good option as it has been a good performer for the last several years.

Last year the SEC temporarily suspended trading of Zoom Technologies (ZOOM) partly because investors were confusing it with Zoom Video (ZM). Zoom Technologies also had not publicly disclosed any financial information since 2015.

From Saturday’s WSJ - Meta Who? :)
“A Canadian company’s stock surged recently. Investors apparently confused it for the rebranded Facebook. Shares of Meta Materials Inc., a material-science company with the ticker symbol MMAT, rose 8% over the past two days. While Meta Materials appears to have little relation to Facebook Inc., it soon will have a similar corporate name.”

Wonder what others’ thoughts are on this fund which is classified by Lipper as Small-Cap Core and is a Great Owl over 3/5/10 years?
It has a five-year upside capture ratio of 112.86, downside capture ratio of 63.68, and max drawdown of 16.24%.
Max drawdown over its lifetime (since May 2002) is 35.75%.
The investor class NESGX is a bit pricey with an ER of 1.89 plus 12b-1 of .25 but its institutional class with ER of 1.22 is available at Schwab with a minimum of $2,500/$1,000 (IRA) and the usual TF.

This topic came up in a different thread. There seems to be a lot of confusion and controversy over these businesses. Solid information is very hard to come by. (I’ve searched for hours.) Apparently, when you access your account at a bank, mutual fund company, brokerage, etc. it’s likely that the actual functionality of that site is being provided by some third party under contract with the firm. Yodlee is one of the largest and a subject of much scrutiny.
One Story
Brief excerpt from above:
Charles Schwab & Co. and Fidelity Investments have finally taken action against "screen scrapers" largely by piping them better data that obviates the need to siphon it intrusively. For the first time, the San Francisco and Boston RIA custodians and retail brokerage giants will openly share data with aggregators -- and competitors like Envestnet-owned Yodlee--as well as each other.
In a nutshell - even if “anonymous” our data is valuable to others like marketers and investment houses who want to know things about how we invest, how much our holdings are worth and whether we’re buying bonds, stocks - or maybe opening a short position. A group of Democratic lawmakers called on the FTC in 2020 to investigate Yodlee for allegedly selling confidential investor information. The FTC took up the case, but I can’t find whether or not anything was ever resolved. I’ve read that a former Trump attorney is suing Yoldee - so they must have antagonized both sides of the political spectrum. FTC Case

Have you heard about the "commodities super cycle" we may be living in right now? .....The topic sentence from this Institutional Investor article sums it up quite nicely, “Commodity super cycles are decade-long periods in which commodities trade above their long-term price trend.”
....in the short run the green movement could well be an inflationary force
I would argue that COVID and nationalism, (and I should add dysfunction in social media and tech itself, i.e. hacking for instance), are inflationary and serve as mitigating forces against rational technology’s deflationary sway. Does nature and irrational human behavior always win out over the better aspects of technology and rational human behavior? Not always, but the wild side, the animal spirits, are ever-present and always set to rise.
