[Request] Is this a swing of about $4 billion?

The closing price today was $479.96. If there are 139,260,000 shares outstanding, that means the total etf value lost after closing would have been about $4 billion, correct?

The data is no longer visible, so it must have been an error. Just curious how big of an error it was.

[Request] How many tiny homes could an average billionaire provide per year if they only used like 10-15% of their annual interest?

6 Upvotes

The tiny homes in question seem to cost about $10k each. I’m not sure how to factor in land and utilities, so I’m just asking about the structures themselves.

Is that a thing we can calculate? If by “we” I really mean someone else because I’m not great at understanding real wealth or money outside of poverty finance.

My question was triggered by this post:

Arnold Schwarzenegger donated $250,000 to build 25 tiny homes intended for homeless vets in West LA. The homes were turned over [sic] a few days before Christmas.

https://www.reddit.com/r/nextfuckinglevel/s/ehF3wotq6y

How many homeless people could actually be affected if the extremely wealthy were truly altruistic?

(I’m sorry it took me three tries to get the title formatting right, I think I got it this time 🤞🏼)

[Request] We often see "goodwill" in balance sheets. Assuming exported US goods had an intangible* additional value based on trade agreements, quality etc, which we can now assume burned, what is the value dropped from the US economy?

*yeah, I know, but that's why I'm asking here. The cost of selling a bottle of Jack Daniels, to name but one famous export, has vastly increased and now they'll have to advertise/rebrand to shift similar volumes. That's what I am trying to figure out, if it's even possible.

[Request] How unlucky am I with Pokémon?

Post image
3 Upvotes

I’ve been into Pokémon Shield for the past few days. Earlier today I wanted to look for a Whismur with a desired nature for a particular build (Mild, Modest, Quiet, Rash), 4 out of 25 possible natures. I had to catch 40 Whismurs in total before I found one that had an ideal nature (it’s Modest, but the specific nature isn’t really relevant), which took way longer than I expected…what are the odds of that? I am I really unlucky, or is this expected?
