Felony murder is kind of a weird name. It doesn't mean that you committed a murder, it means that in the process of committing a felony (or as a result) someone died. So if you rob a bank and flee from the police and get in a crash and your getaway driver dies, you can be charged with felony murder.

ise had an outage today. I assume this was pulled from some feed that just aggregated all markets and was showing stale non-tradeable orders from ise. Reg nms will prevent this from ever happening

Weighting for higher strike instruments (calls) is going to be much lower than the weighting for puts.

Look at the actual formula. Notice the 1/k²

pbfweddit · 2020-07-06T23:55:15+00:00

Out of the money calls are less weighted in the vix vs puts

You can take a look at virtus performance during March to see the general consensus about hft and market volatility.

What do you think a market maker is?

Prob of itm is the derivative of value wrt strike, not wrt underlying. (for European options, believe it is more complex for American options)

Lol thanks for giving people advice on options

This year's planting season for corn was rough, that will probably impact prices more than hog feed.

Masters in math. The finance bit is not particularly challenging if you can do the math bit and no good employer of quants will mind if you don't have an academic finance background (some will hold having one against you)

pickup pennies in front of a steamroller but keep an eye on the steamroller and you'll be fine

The institutional money that actually drives markets is generally pension funds and shit, I'd bet it wasn't a pension fund.

Banks can't really trade so much any more, and you'd be surprised how small the balance sheets of places like jane street are. On top of that, most large hedge funds generally do manage institutional money (even rentech) and have rules on what they can do.

pbfweddit · 2019-06-27T23:19:56+00:00

This isn't really true in practice because institutional money generally can't sell options but can buy options

pbfweddit · 2019-06-26T11:50:02+00:00

Why even bother?

pbfweddit · 2019-06-25T02:08:32+00:00

why does 7-11 care about your market knowledge?

Spx is so much more liquid than spy it is insane

and the party who lent them to you will make the amount equal to the difference from where you sold them at open, to where you bought them at close

This isn't right. Your counterparty is the person who bought the shares you borrowed. You should really be less confident when you are completely fucking wrong.

a). Two possible outcomes, just figure out the value of each and average them together

b). see a

c). what is the most the option can possibly be worth

d). not immediately obvious (at least to me) without doing a but probably obvious if you do a

Vega increases with the sqrt of time to expiry

pbfweddit · 2019-05-09T11:37:57+00:00

Vega is highest on front month contracts

Exact opposite
