Options markets: How low have implied transaction costs?

The primary development within the choices markets over the previous 20 years has been declining buying and selling commissions. At first, many brokerage teams had been charging $10 for a commerce. That dropped to $5 a commerce in 2010, and right now Robinhood and different platforms provide commission-free choices buying and selling.

However whereas the express prices of choices buying and selling have fallen to close zero, what in regards to the implicit transaction prices? We explored this query by inspecting how the typical bid-ask unfold in choices markets adjustments over time.

We chosen 20 corporations which have traded within the choices markets since 2000, amongst them corporations resembling J&J, Amazon, Goldman Sachs, AT&T, and P&G, then tracked every firm over time and in contrast the typical bid-ask unfold, on a proportion foundation. , shifted between 2000 and 2020.

To manage for different elements resembling open curiosity, quantity, and notional charge, we ran an identical process that averaged the bid-ask spreads for the 4 sorts of choices—in-the-money calls, put places, and out-of-the-money calls and places—for the 20 corporations concerned and included solely the outcomes of these choices for which the variance was least About 10% in open curiosity/quantity/nominal charge.

We discovered that the bid-ask spreads decreased on each places and places. However the transaction prices of in-the-money choices — these during which the strike value is decrease than the inventory market value — have fallen greater than their out-of-the-money counterparts.

This exhibits how market makers nonetheless cost possibility consumers hefty charges. Particularly, market makers proceed to obtain giant implied charges from buyers, particularly those that wager on tail threat occasions, that’s, those that purchase out-of-the-money choices.
