Ether Call Options Look Attractive Relative to Bitcoin as Volatility Spread Dwindles

Options are derivative contracts that give the holder the right, but not the obligation, to buy or sell the underlying asset at a predetermined price on or before a specific date. A call option gives the right to buy, while the put option confers the right to sell.

Buying a call/put option is akin to purchasing insurance against bullish/bearish moves. The buyer compensates the seller for offering protection by paying a premium while taking the trade.

Matrixport's suggestion involves collecting a premium by selling a bitcoin () call option and using the same to fund the purchase of an ether () call option.

The trade idea is based on the assumption that the spread between the annualized 30-day realized or historical volatility of ether and bitcoin would bounce from the current unusually low level. That, coupled with the upcoming Ethereum Shanghai upgrade, would make ether calls pricier relative to bitcoin calls.

"The volatility spread between ether and bitcoin has compressed to below 1. This has only occasionally happened and the spread has traded above 1 in 93% of the observations during the past four years," Thielen noted.

Volatility is mean-reverting and has a positive impact on options prices. In other words, periods of unusually low volatility are followed by increased price turbulence, which, in turn, boosts demand for options, making them pricier. Thus, traders tend to buy options when volatility is lower than its long-term average.

The spread between ether and bitcoin realized volatility gauges looks undervalued relative to its historical standards and could mean-revert as we head into the Shanghai upgrade, which is expected to bring price turbulence.

"The spread has averaged 1.39 over the year and offers great risk/reward potential here," Thielen noted, explaining the rationale behind purchasing ETH calls by selling BTC calls.

The Shanghai upgrade, a backward-incompatible hard fork due sometime in the coming weeks, will open withdrawals of ether staked in the Ethereum network since December 2020. The upgrade will de-risk staking and increase capital efficiency, opening doors for more investor participation and perhaps ether price gain.

"A wave of new participants who had previously been watching from the sidelines can potentially add a level of buying pressure to ETH, especially if institutional capital can be enticed," BINANCE Research said in a report last month.
