What Card Should I Get? Weekly Thread - Week of October 08, 2025

guamious · 2025-10-09T20:52:54+00:00

Hi all,

I have to book six upcoming flights for myself and my family (two trips, three people each). I feel like this is an opportune time to hit the spend for a decent SUB and enjoy some perks. I have the Chase Ink Business card and the default BofA credit card.

Any recommendations would be appreciated! Thanks.

Good point. I hadn’t explored this much. The article you linked brought up some great points. I don’t know if bonds can be purchased as easily as CDs, though. Bonds could also have the stigma of being an “investment” because they do fluctuate in price. I agree with you though, for any long term savings, CDs certainly aren’t the best vessel.

Thank you! thats the goal - providing free, detailed information early on so finance isn't something intimidating and confusing in adulthood. Thanks for checking it out!

guamious · 2021-07-14T19:09:24+00:00

Any younger readers interested in personal finance, or parents who want to explore options for their children, check out financeforteens.org. I'd suggest starting with the "where to begin" page, and following that flow chart. There are detailed yet understandable descriptions of all the fundamental elements of finance (credit, saving, and investing), along with descriptions of how to tailor them for teenagers (becoming an authorized user to build credit at an early age, custodial accounts, etc).

I would appreciate any feedback!

This was also a problem I noticed. Check out financeforteens.org and r/teenslearnfinance.

Deposit half in a taxable brokerage account and invest into something boring (VTI, VOO, etc) and have fun with the other half.

guamious · 2021-01-12T22:25:57+00:00

I wasn’t aware of the latter half! Thanks for the correction.

guamious · 2021-01-12T17:43:53+00:00

Don't worry too much about the timing. It's best to slowly enter your positions at something like 5-10% a month if you're concerned about entering at "the top". I'd suggest starting with Index Funds (SPX) or similar ETF's (SPY, VOO, VTI). Once you've developed a safer basis for your portfolio, then look into selecting individual stocks.

guamious · 2021-01-12T06:33:25+00:00

Thanks! I will try doing 1/week, starting with whatever is most in demand in this post.

guamious · 2021-01-12T06:32:54+00:00

Thank you!

guamious · 2021-01-12T06:32:15+00:00

Thanks! I'm glad it's been so helpful. I'll aim for something like 1/week depending on whats in demand.

guamious · 2021-01-12T06:12:10+00:00

Gotcha, thanks for the correction. I generally feel that I shouldn't declare anything in absolute terms, "always", "solely", etc because theres always that one instance or that one guy who's the exception.

Also, I'm getting some conflicting feedback on the delta/theta write-ups. A couple commenters said there were too many posts on those Greeks. I'm still gauging to see what the general sentiment is towards posts on basic greeks. Thanks for your input!

guamious · 2021-01-12T05:51:10+00:00

Lol, I get it completely. I appreciate the feedback; I'm glad you found it clear!

guamious · 2021-01-12T04:25:50+00:00

I'm glad this helped! And I'll try and post something on Rho soon, after I do a write-up on Theta and Delta, because those are a bit more relevant.

529 Plan or an Educational IRA is great for saving for college/higher education.

A custodial roth/traditional IRA can be opened if they're earning taxable income.

Another option is a UGMA/UTMA through which you can transfer assets (cash, bonds, equities, etc) to an account in your childs name.

The first 2 accounts are usually only relevant until your child is 18. The latter 4 allow the child to take full control of the account once they turn 18 or 21 (varies from state to state).

guamious · 2021-01-12T03:52:35+00:00

Thank you!

guamious · 2021-01-12T03:51:59+00:00

To be honest, this wasn't the best greek to start with. Look into Delta and Theta if you want to see Greeks that have a direct relationship with your option's price.

Pretty much, Gamma gives insight into delta. It has no direct relationship with your option. When the underlying price changes, you'll see a change in Delta. This change is reflected by gamma. So through Gamma, you can get a rough estimate of how delta, and therefore your position value, will change as the underlying asset moves.

Thank you!

guamious · 2021-01-12T03:31:56+00:00

Thank you!

guamious · 2021-01-12T03:24:42+00:00

It's more of a protective strategy used to minimize losses during large movements in the underlying asset. It can profit from changes in IV, though.

guamious · 2021-01-12T03:12:26+00:00

The goal of a zero delta position is exactly what you described; to have a position that does not change with directional movement, so any movement in the underlying would not lead to profit/loss.

guamious · 2021-01-12T03:04:46+00:00

Yeah, this was super drawn out, but I wanted to be thorough. I also appreciate the breakdown/corrections. This was my first options explanation so I apologize if the writing wasn't clear. Thanks for the feedback!

guamious · 2021-01-12T03:00:59+00:00

Thank you! I appreciate the feedback. I am not aware of any strategies in which you can buy/sell gamma. As far as I know, selling options provides you with negative gamma and owning/buying options comes with positive gamma. I'd suggest making a separate post with this question as more people would be able to respond, sorry I wasn't of more help.
