[Editor's note] Options are derivatives used to take leveraged exposure to an underlying asset or hedge existing positions. Calls give holders the right to buy at a specified strike price, while puts give holders the right to sell, subject to the contract's terms. Open interest measures outstanding contracts and indicates the size of accumulated positions.

Comparing call and put shares across open interest and trading volume helps distinguish accumulated positioning from recent trading activity. Rising open interest indicates an increase in outstanding contracts, but does not by itself establish a directional outlook. Call and put activity can reflect both speculative positions and hedging demand.
