Buying vs Selling Options
Buying vs Selling Options
Every options trade has two sides: a buyer and a seller. Understanding which side of the trade you are on is critical because buyers and sellers have fundamentally different risk profiles, profit potentials, and probability of success. As a wheel strategy trader, you will almost always be the seller.
The Buyer's Perspective
Option buyers pay premium upfront for the right to exercise. Their maximum loss is limited to the premium paid, but they need the stock to move significantly in their favor before expiration to profit. Time works against buyers -- every day that passes, the option loses a little value (time decay). Statistically, a large percentage of options expire worthless, which means buyers lose money more often than they win.
The Seller's Perspective
Option sellers (also called writers) collect premium upfront and take on the obligation to fulfill the contract if the buyer exercises. Time decay works in the seller's favor -- premium erodes every day regardless of stock movement. Sellers can profit even when the stock moves slightly against them, as long as it does not breach the strike price by expiration. The tradeoff is that sellers face larger potential losses if the stock moves dramatically.
- +Pay premium upfront
- +Limited loss (premium paid)
- +Need large stock move to profit
- +Time decay hurts your position
- +Lower probability of profit
- –Collect premium upfront
- –Profit is limited to premium received
- –Profit when stock stays flat or moves in your favor
- –Time decay helps your position
- –Higher probability of profit
- Sellers have a statistical edge because time decay erodes option value every day.
- Sellers can profit in three scenarios: stock goes up, stock stays flat, or stock drops only slightly.
- Buyers need the stock to move enough to overcome the premium paid (breakeven = strike +/- premium).
- The wheel strategy uses selling exclusively, turning time decay into a consistent income stream.
- •Option sellers collect premium and benefit from time decay; buyers pay premium and fight against it.
- •Sellers profit more often but accept larger potential losses on individual trades.
- •The wheel strategy is a premium-selling strategy -- you are always the seller.
- •Only sell puts on stocks you are willing to own at the strike price.
