Finance is a super competitive "blood from a stone" business. It has a lot of optimization to squeeze perma-threatened margins.
It's draining in that zero-sum way and because it's a scale business the rewards return to scale (& owners)
As the last year showed, optimizations often revolve around liquifying excess capacity, redundancy.
It's short vol in that sense since options are sold. Time decay on slack, will cost you customers in short term.
As @moreproteinbars mentioned on Corey's pod the fear in commodities is to the upside because shortages are what destabilize markets
(Oil call skew is anti-correlated to excess days-to-cover)
Anyway...
Almost a decade ago I was hanging out with a former banking guy who moved over to semi-mature tech company.
I say sem-mature because they were past hyper-growth and now started valuing optimization. He was able to be major value-add because he was used to that thinking...
And the tech company didn't have that in their DNA.
So he found his experience to be highly complementary and he enjoyed work because he felt like an important contributor.
He took a pay cut and never was happier.
He said being gone from finance lifted a huge weight. The mindset of finance seeped into him.
I suspect tech jobs can be just as soul-sucking as finance gigs, I know better than to be pollyannish about this crap. In fact, finance can prolly be less dissonant in the raw honesty of it if you are in the trading game. It's about little more than $$ to me.
I happen to like finance as a general puzzle (prolly more than I care to admit since I enjoy writing about it insofar as anyone can actually "like" writing) but the business of it is...well let's just say I'd be happy to spend brain cycles on other sht
Anyway, just a feeling I thought to share, esp since I know many people out here understand. This biz is filled with sociopaths esp as you climb. I probably don't even realize how much of a sociopath I am (i get hints every now and then)
Idk much about other fields and maybe all of this is an artifact of competition (actually reminds me in Zero to One how the virtue of a monopoly was lauded because of the downside of crushing effect of competition. Many would point to its author as sociopath in chief, ymmv)
But anyway, at an individual level I do think that the sense that your contribution matters and that you are not interchangeable is important. So it's worth thinking about what you are good at, who needs that, and who is in short supply of it.
Done with the🚿 thought now.

None of this should be attempted at home unless you listened to @darjohn25 with Corey and thought "yea, I could do that"
it's more natural to use vol-informed ideas to structure directional option trades (if you dig thru the vol wiki there's plenty on how to think about this)
Banks and market makers get short say an 80%-60% put spread every year due to the annual Hacienda hedge. If the market drops, vol beta is strong...but what if the market trades below that 80% strike...
Now the hedgers are short an ITM puts and long an OTM put. In other words, they went from being short a PS to being long skew on risk reversal. The inventory causes the call skew to firm, and the vol beta to decline to the downside as dynamic hedgers are no longer stressed lower
The best trading/mm firms aren't just capturing spreads. They use market intel to read the table and make big bets. Obsession was finding real EV knowing they had bankroll to bet big when they found it.
It ties back to a lesson I've mentioned before and makes sense when your bankroll is large
if you make money every day you're leaving money on the table
You don't close trades unless your getting edge to do so.
Like Darrin said on @choffstein pod...if you sell a tail you must collect the whole premium otherwise the times you lose multiples mean you def have neg ev
Building sims instead of backtesting as a way to get more samples. Table stakes to get a fingertip feel especially when you don't get the apprentice experience
(btw, doing this gig w/o being an apprentice sounds impossible so huge props to Darrin)
The idea of pricing out financial products to the penny. Darrin called it "back-office" kinda stuff that retail doesn't do. Corey said he does this too.
This is exactly what you do at a mm/arb shop. Giant spreadsheets pricing fair value for financial products. Not optional work
