Editor’s note: Options are derivatives used to take leveraged positions on an underlying asset’s price or hedge existing exposure. A call gives the holder the right to buy at a predetermined price, while a put gives the right to sell. Open interest measures the total number of outstanding contracts.

Call and put shares, together with changes in open interest and volume, can help distinguish medium-term positioning from short-term trading. Rising open interest indicates new positions entering the market, while differing open-interest and volume skews may reflect simultaneous directional and hedging demand.
