About Open Interest

• It is a term commonly used in Futures and Options (F&O) trading, where the number of open contracts changes on a daily basis. 
  • In simple terms, every trade has two sides: a buyer and a seller. Whenever an F&O contract is traded, it is considered open until one of the parties closes their position through offsetting. 
• Open Interest is the total number of active options and futures contracts that have not yet been settled against an asset at a given time in the trading arena. 
• It is primarily used as an indicator to identify market positions of securities that have not yet been closed for an unknown reason. 
• To summarise, it is referred to as a measure of liquidity in conjunction with market activity. 
• Like any other security traded in the market, it is subject to market changes.
• When new contracts are created or opened, it rises. A rise in the number of them indicates that there are more buyers and sellers for a specific security. 
• It decreases when positions in existing contracts are closed out by buyers (or holders) and sellers. 
• Investors might make conclusions about the day’s market activity by monitoring changes in the open interest at the end of each trading day.
• Importance of Open Interest in Stock Market:
  • Open interest plays a significant role in helping options traders understand the liquidity of an option.
  • It is a measure of market activity. It indicates if a market will trendor be range-bound, often known as choppy. 
  • An increase in open interest indicates that the number of new positions is increasing. This suggests that the market is being traded actively and is more likely to trend, while decreasing open interest indicates money flowing out of the market.
  • After a sustained price gain, a levelling off of Open Interest is usually an early indicator of the end of a bull market phase.
  • To summarise, this type of indicator can be a significant piece of information when evaluating a possible investment.

What are Futures and Options (F&O)?

• F&O are the major types of stock derivatives trading in a share market. 
• These are contracts signed by two parties for trading a stock asset at a predetermined price on a later date. 
• Such contracts try to hedge market risks involved in stock market trading by locking in the price beforehand.
• F&O are contracts which derive their price from an underlying asset (known as underlying), such as shares, stock market indices, commodities, ETFs, and more.
• Futures contracts obligate the buyer to purchase an underlying asset, while the seller must deliver it at a predetermined price and date. 
• In options contracts, the buyer has the right, but not the obligation, to buy or sell the underlying asset at a predetermined price and date, while the seller must honour the contract if the buyer chooses to exercise their option.
• F&O basics allows individuals to reduce future risk with their investment through pre-determined prices. 
• However, since a direction of price movements cannot be predicted, it can cause substantial profits or losses if a market prediction is inaccurate. 
• Typically, individuals well versed with the operations of a stock market primarily participate in such trades.
