Cboe Ditches Caps: Unlimited Bets on S&P 500 Allowed?
Published Date: 3/31/2025
Notice
Summary
Cboe Exchange wants to remove the limits on how many options traders can hold or exercise for certain S&P 500 Equal Weight and ESG Index options. This change affects investors trading these options and could let them trade bigger positions starting soon after approval. It’s a move to boost flexibility and possibly increase market activity without changing costs directly.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Remove Limits on Certain S&P 500 Options
If the SEC approves the filing, Cboe would eliminate position and exercise limits for options on the S&P 500 Equal Weight Index (SPEQF and SPEQX) and the S&P 500 Scored & Screened (SPESG) Index. This removes the current 25,000-contract position/exercise limit and the 200,000-contract FLEX limit for those options.
May Increase Market Liquidity and Hedging Flexibility
Cboe says removing these limits could let market participants execute larger hedging and investment strategies using SPEQF, SPEQX, and SPESG options and may add depth and liquidity to trading in these options. The Exchange cites the large market capitalization of the S&P 500 (about $49.788 trillion as of January 8, 2025) and high average daily trading volume (about 2.7 billion shares for the six months preceding January 8, 2025) as part of its rationale.
FLEX Options Keep Reporting Requirements
Even after limits are removed, FLEX SPEQF, SPEQX, and SPESG options will remain subject to the same reporting requirements that apply to other FLEX options traded on Cboe. Traders who use FLEX versions of these options must comply with those reporting rules.
