Great thoughts. The second point has been what has worried me the most.

Presuming entirely rational actors with perfect information (and the
ability to act on it), the spot price (if it is truly a market price)
should never rise above on-demand. But, switching instances is far
from frictionless so invariably you have the likelihood of creating
the third point (spot is more expensive).

I wasn't aware that the spot price had ever risen above on-demand. I
find it pretty fascinating though that it has already happened.

I can't remember the source, but Rahul has a great similar quote: "I've never regretted going on a run, but I have regretted skipping one."

This is simply awesome. Truly, truly helpful.

Thanks a ton for contributing this. I feel that you've taken it to
another level!

I'm not a tax lawyer, etc. This is something you'll want to run by
someone who is much more qualified than myself...

My understanding is that you have to file an 83b the moment you
receive the full grant. The type of vesting used on stock grants is
typically the reverse vesting of the company's right to repurchase the
stock. So, you own the stock right at the grant - and as your time
there increases, the company's right to repurchase the stock lifts.

Now, that would be something.

Andrew,

Awesome, detailed and super-helpful writeup! Thanks for sharing this
- it should absolutely help future readers.

Enjoy your trip!

Nice - it looks clean.  I'll check it out!

Ray, this is super-helpful.  Thanks for sharing!

I'm pretty sure the visa is for you, not your passport.  I would think you'll be ok.  Please let us know once you get it.

Hmm, good question.  This is unfortunately outside of my sphere of knowledge.  I'd suggest making a quick call to your accountant.
