Editor’s note: Options are derivatives that investors can use to take leveraged positions on moves in an underlying asset or to hedge existing exposure. A call option gives the holder the right to buy the asset at a predetermined price at a future date, while a put option gives the holder the right to sell. Open interest measures the total amount of options contracts still outstanding in the market and indicates the accumulated size of positioning.
The balance between calls and puts, along with changes in open interest and volume, can help distinguish medium-term position building from short-term trading responses. Rising open interest indicates the entry of new positions and can suggest increased betting on a medium-term price view. Even when calls dominate open interest, a higher or concentrated share of put trading may indicate defensive positioning against short-term pullbacks or demand to manage volatility.
