Short-term dated options are continuing to grow in popularity which many analysts are warning could have unintended consequences for market stability according to a Reuters article by Saqib Iqbal Ahmed.

The fastest growing segment is zero days to expiry (ODTE) options, where traders are looking to profit from small, intraday market moves. Most options are based on indices, popular ETFs, or single stocks. As of March 2022, the daily notional value of all ODTE trades had exceeded $1 trillion.

The contracts are popular among buyers, because small moves in the underlying instrument can result in huge moves for its derivatives. For sellers, the appeal is that the options decay in value and the trade can be closed at the end of the day. 

However, many warn that large positions in these options could set off a ‘squeeze’ in the event of an unexpected, intraday move. This would cause option sellers to take large losses and potentially force hedging which could exacerbate the move in the underlying instruments. According to JPMorgan, it would be a similar dynamic to the ‘Volmageddon’ crash of 2018 when many inverse volatility products crashed due to a large spike in the VIX.

Finsum: A new threat to market stability is the rise of ODTE options which are becoming very popular with retail and institutional traders. However, they do have the potential to exacerbate large, intraday market moves.
