Buyer risk vs seller risk

The option market has exactly two parties: the buyer (holder) and the seller (writer). Their risk profiles are completely asymmetric, what the buyer gains, the seller loses, and vice versa.

The option buyer's position

• Pays premium upfront
• Maximum loss: premium paid (known, limited, upfront)
• Maximum profit: theoretically unlimited (call) or strike − premium (put)
• Probability of profit: typically below 50% for OTM options
• Time is enemy: premium decays every day against the buyer

The option seller's position

• Collects premium upfront
• Maximum profit: premium collected (known, limited)
• Maximum loss: theoretically unlimited (call seller) or large (put seller)
• Probability of profit: typically above 50% for OTM options
• Time is friend: premium decay works for the seller

> SEBI's 2023 study: over 90% of individual equity option buyers lost money. Option sellers have statistical edge, but when they lose, they can lose catastrophically.

The leverage difference

Buyer: fully leveraged. A small premium controls a large contract.

Seller: must post margin. The margin requirement for selling is similar to futures, substantial.

The two extreme failure modes

Option buyer failure: buys 20 OTM calls. All expire worthless. Loses 100% of premium. Common.

Option seller failure: sells 1 naked call. Stock gaps up 30% overnight. Loses 10× the premium collected. Rare but catastrophic.

Buyersmall frequent losses, occasional large wins

Sellerfrequent small profits, rare catastrophic losses

Neither is inherently better. Professional option sellers always hedge, never fully naked.

Takeaway. Buyers: limited loss, unlimited profit potential, time works against you. Sellers: limited profit, unlimited risk, time works for you. Both are valid. Risk management is what separates survivors.
