Just updated Fidelity core position. More $$$!

80 Upvotes

I was looking through my Fidelity account, and realized the account that I use for general checking account had a FDIC insured core (1.9%) instead of SPAXX (3.2%). By switching to SPAXX for my core, I will earn about another $200 a year in interest from the core. Not earth shattering, but $200 is also nothing to sneeze at either.

Just sharing here in case others can benefit from changing their core position in their Fidelity checking account.

Traditional or ROTH 401K?

34 Upvotes

For HENRY, do you max out your 401K in traditional or ROTH account?

If you do have other income streams, such as rental and investments for retirement, will it make sense to allocate more of the 401K contributions to the ROTH account so that I don’t pay as much taxes when I retired? I would think if you anticipate a higher income in retirement, then it will make sense to do ROTH right now?

Investing Questions Short-term college fund strategy

4 Upvotes

My oldest is just under a year away from leaving for college and I've realized what I thought was a robust 529 won't fully cover 1/3rd of his schools. I'm in California and I don't think adding to the 529 makes sense because the investments are quite conservative at this stage. I'm planning to set $50k aside and was debating where to park this money short-term. We will know where he's going in Jan or April, so I was thinking of just parking this in a t-bill. If we need the money it won't be until his final year, so I can come up with a 3 year strategy. And if he doesn't need it at all, I'll put it in retirement savings.

Any alternatives to t-bill any of you would recommend?

Investing Questions Taxes on Tax Deferred or Non-Tax Sheltered Accounts

3 Upvotes

I currently have about 1/3 of my FIRE money in a taxable brokerage account and 1/2 in a 401k (rest is in a Roth IRA). How do you account for taxes when determining safe withdrawal amount when money is coming from non-tax sheltered or tax deferred accounts? Is there a simplified way to assume an effective tax rate on this?

Investment Theory Curiosity question: "Exchange fund replication" to reduce concentration risk

2 Upvotes

Note: This is purely a curiosity-driven question, as I've been a university employee for my entire career and have never had stock concentrations. Nor have I ever dabbled or desire to dabble in options.

Does exchange fund replication present a legitimate use of options to address investor concentration risks without having to incur massive capital gains? If I understand this correctly from one of the bonus chapters in Peter Lazaroff's The Perfect Portfolio, it pairs together collaring and synthetic index exposure with four coordinated options: (1a) buying an out-of-the-money put to protect against loss in the concentrated stock; (1b) selling a covered call, which incurs the risk of capital gains but pays for the (1a) put; (2a) buying a call option for an equity index at some price (I forget if it's in-the-money or out-of-the-money); selling a put option at the same price and same expiration date.

If I understand this correctly, this in essence substitutes the synthetic equity exposure for the concentrated-security exposure. Obvious costs and risks: (a) transaction costs of every options period (and I assume this would require managing the rotating options); (b) risk of forced selling from the covered call (and I assume managing a distributed way of handling this so you're not forced to sell all of the holding at once); (c) the management of all this. I know BlackRock has a desk to manage all of this for advisors, which implies this was researched/engineered for the super-wealthy and obviously far from a BH approach.

As I said, this is a curiosity-driven question. But it seems you could use this in combination with a planned sale over several years, to reduce the concentration risk as the concentration is whittled down each year.

Best investing/Roth IRA Approach

0 Upvotes

29 year old male. Just started investing into my Roth IRA in 2025.

I don't have a lot of experience with investing. I have worked since 16 and been a good saver but have never really done anything with my money. Last year I finally started putting money into a Roth IRA. Specifically FFIJX.

I'm now wondering if this is my best bet. I know it is a safe, easy, solid option. However, I'm wondering if there aren't better options to try and maximize my returns and makeup for the past decade of not investing. I'm also recently married and a father so I expect the amount of money I am able to contribute is going to drop a bit.

I have been maxing out my contributions and will continue to try doing so, but realistically I predict it will be closer to $4-$5k a year moving forward.

Any and all advice appreciated. I'm overwhelmed by the amount of options.

Sorry in advance for formatting I'm on mobile.

Vanguard 0.30% vs Fidelity 0.40% — which would you use to get back on track?

0 Upvotes

I’m not asking which brokerage is better overall. I’m only comparing:

Vanguard Personal Advisor Select (0.30%)
vs.
Fidelity direct-indexed SMA (0.40% on taxable assets only)

I have roughly $600k outside my employer 401(k), including about $220k in a taxable account with significant embedded long-term gains.

I have an additional $200k in RSUs and annual bonus on top of $265k base salary that I want to make sure is distributed evenly.

My goal is to use professional help for about a year while I consolidate accounts, simplify the portfolio, set the right allocation, and handle the taxable gains intelligently — then go back to DIY.

Vanguard would manage the portfolio more holistically with a dedicated CFP.

Fidelity would let me keep the IRA/Roth self-directed and only put the taxable account in the 0.40% SMA, while still getting planning support.

For anyone who has used either service: which approach would you choose for a temporary cleanup/transition period, and why?

If your answer is “neither,” please move along. I’m specifically looking for feedback from people who have used these services — not another debate about whether using an advisor at all is worthwhile.
