19:18:40 mircea_popescu: "how one never enters naked options positions, while simultaneously never hedging options positions"
19:18:57 mircea_popescu: aka, "how does one not steal clothes while also not returning them"
19:19:15 mircea_popescu: forum muppets never heard of this mystical concept of, you know... like having money ?
Split sides eagerly await your doubtlessly clever and well-grounded retort.
Despite my better judgement warning me it is an utter waste of my time to respond to such ongoing flailings and desperate attempts to lower the tone of the conversation, on this occasion I will accept the invitation to explain the inherent idiocy of claiming to provide
competent options market making services while never hedging options positions
and never entering naked positions.
By definition, an options market maker is a
guaranteed buyer, and a guaranteed seller. The market maker does not get to decide, in advance, whether they're going to be buying or selling, and the market maker does not get to use a crystal ball to tell them, in advance, what demands are going to be made either to buy or sell options or to deliver or to take delivery of the underlying.
As a result, any competent market maker -- who, being
competent and all, is not going to introduce inordinate levels of counterparty risk -- continually adjusts positions both in cash and in the underlying entity which are sufficient to cover their obligations created by ongoing sales and purchases of options. That's in addition to ongoing adjustments to bids and asks across option chains so as to accommodate changes in the price of the underlying and fluctuations in demand for the options. In my original example, when they're short a call, they might ensure that short position is balanced by a long in the underlying -- and, notably,
maintaining that long position, whose price moves inversely relative to the short position, is the very definition of hedging. To the extent the position is covered, it is hedged -- by definition. Someone who claims otherwise either does not understand the meaning of the words, or they hope that you don't.
(I'm simplifying quite a bit here. More generally speaking, options market makers keep a lid on directional risk, or delta risk, via a range of strategies, including using futures. They also keep a lid on risks associated with the other Greeks -- gamma, vega, and theta -- but we're dealing here with someone who claims to provide competent market making while ignoring the obvious delta.)
The types of adjustments I've just outlined explain why, generally speaking, competent market makers tend
not to lose large amounts of money: a competent market maker is not merely gambling with a pot of underlying capital by buying and selling options willy-nilly, hoping to make a killing on the bid/ask spread. On the contrary: their entire operation is designed and delta hedged so as to
avoid wild swings in the net value of their position and to provide a service which is both extremely reliable for market participants -- by virtue of continually ensuring their ability to deliver on their obligations -- and highly profitable to themselves.
Merely "having money" and providing a bit of options market making without a grasp of the basic mechanics of risk management in the activity does not make one a competent market maker; it makes one a gambler.
Merely "having money" and occasionally losing large sums while options market making does not make one a competent market maker; it makes one a source of counterparty risk.
The bottom line is that out in the real world of finance, a supposed market maker who not only failed to grasp the concept of delta-neutral hedging but actively promoted their lack of hedging activity as some sort of good thing would be laughed out of the room -- or more likely just ignored. Only here, where Bitcoin finance remains in its infancy, can someone swagger in without a clue about even basic delta hedging, point to a big bag of money, and attempt to browbeat and intimidate folks into thinking that that somehow implies they know what they're doing and can be relied upon as a safe counterparty.
