How Options Dealer Hedging Can Amplify or Dampen Price Moves

Article Quant Q&A · Author: Jorisdrees

Summary

The document addresses whether market makers’ dynamic hedging pushes an underlying asset toward options “max pain.” Its answer distinguishes the effect of dealers’ net option positions. Dealers who are long options tend to sell as the market rises and buy as it falls, trades that can counter price moves. Dealers who are short options tend to buy into rises and sell into declines, which can intensify moves.

A second response qualifies the price impact: hedging trades do not necessarily move the underlying directly, since dealers may hedge through futures. The discussion gives a qualitative mechanism, not empirical evidence that prices converge toward max pain. Its effects depend on dealers’ aggregate positioning and hedging instruments, and the document does not quantify their market impact or explain max pain as a predictive strategy.

Key ideas

  • Long option positions tend to produce hedging trades that counter underlying price moves.
  • Short option positions tend to produce hedging trades that reinforce underlying price moves.
  • Dealer hedge direction depends on whether dealers are net long or short options.
  • Hedging through futures may not create the same direct pressure on spot prices.
  • The explanation does not show that market prices are driven toward max pain.

# Option Prices Affecting Underlying value Through market makers max pain












In function of the quarantine I started to dig a little deeper into the "Max Pain" principle and how market makers who write the options have to hedge the risk.

What I understood so far: Options are written by the market makers which in turn have to cover their naked option writing with the underlying value. They do this by remaining dynamic hedging to remain neutral. This causes the underlying value to be bought and sold.

This is the part where I get a little confused: If the underlying value rises then the value of a long call option will increase which causes the market makers to hedge more.

Is this done by buying more of the underlying value and therefore creating a diminish returns effect?

I also do not really understand why This rebalancing provides a force driving the stock to toward max pain.

If anybody could help me or point me into the right direction I would be really appreciative!

thanks in advance!

If market makers are long options (either puts or calls) , the rebalancing trades that they do tend to limit the market movement, since they are selling when markets rise and buying when markets fall. If market makers are short options (either puts or calls ), then the rebalancing trades that they do tend to exacerbate market movements , since they are buying when markets rise and selling when markets fall.

Effectively, your example describes a market where your market makers are not ‚atomistic‘ anymore with respect to their influence on (underlying) prices. On the other hand, MM not only employ the spot market for hedging, but also the futures market, where an increase in a ‚position‘ does not, by itself, imply an upwards pressure on the spot markets.
