If price is nearing the top or the bottom part of the range, and Open Interest is starting to decrease, it suggests that price may bounce off the wall of the range and reverse as this shows that traders are closing out of their current positions. An increase in Open Interest means that there is an increase in contracts for that particular stock or ETF, which means that there is more money flowing into the market. An increase in implied Volatility means that the market is stating that there is an increased chance that price will move further from its current location. If Open Interest is increasing and Implied Volatility is increasing, it implies that the current trend will continue. If Open Interest is decreasing and Implied Volatility is decreasing, it implies that the current trend may halt or reverse. So that is using Option Open Interest and Implied Volatility as sentiment indicators. An increase in Open Interest means that there is still an increase in contracts for that particular stock or ETF, which means that there is more money flowing into the market. In this video, we will look at using Option Open Interest along with Implied Volatility to measure market sentiment.
If Open Interest is increasing and Implied Volatility is decreasing, it implies that the current trend may level off. As price moves toward the edge of the range, if Open Interest is increasing and Implied Volatility is increasing, it implies that price may break out of the range. If you remember from my overview video, Option Open Interest is the number of outstanding option contracts or positions in the market. ETF is in an up or down trend. An increase in Open Interest means that there is an increase in contracts for that particular stock or ETF, which means that there is more money flowing into that market. If Implied Volatility is also decreasing, this helps confirm the possibility that price will bounce off the walls of the range and reverse.
ETF is in a range. However, the decrease in implied Volatility means that the market is stating that there the chance of price moving further is decreasing. Option Open Interest is one of the key sentiment indicators that traders look at to help gauge the next step for price. The decrease in Open Interest means that the number of outstanding contracts is going down from traders closing out of their positions, and the decrease in implied Volatility means that the market is stating that the chance of price moving further is decreasing. But if the open interest falls and option price does not increase at the same pace as the stock, it is an indication of profit booking and very soon the rally would be over. We shall look at some of the important terms and ratios in the options market that can benefit a trader in his short term trading.
The general perception is that understanding the math behind option pricing is too complex. This means that if the if the Put Call Ratio is high, more retail is betting on the market going down, then a professional trader would bet on the market going higher. With such high levels of trading taking in the options segment a trader who does not trade in these instruments should still know the basics of what options data are signalling. Structurally Indian markets have changed since the time derivatives were introduced on the pretext of providing a hedging instrument to retail investors and funds alike. Transfer of movement between these markets is a result of arbitragers who search and capitalise on mispricing opportunities. We shall not get in the technical definition of the option of the complex strategies and writing of options. There are two ways of calculating Put Call Ratio.
Though there are numerous strategies in options trading knowing the basics by watching the above mentioned data can be helpful in judging the probability of the market direction. This would be an indication that the rally is nearing its end. In the case of put options their prices rise if market falls and they lose value if markets are flat or rise. This facility of judging the sentiment is not possible in the cash or the futures market as bulls and bears cross each other out with each transaction. Thankfully a trader need not requires knowing the calculation behind the options. The key in trading on this method is in knowing the historical levels of the Put Call ratios, where are the extreme levels and what are the average levels between which the market gyrates. There are two ways a trader can use the ratio. However, the benefit of leverage and high volatility has increased its popularity and the instrument is mainly used by speculators rather than hedgers.
Trading after all is about dealing with probabilities and uncertainties and profiting from it. However, in options the bulls can trade separately by taking long positions by buying calls and bears can trade by buying puts. Open Interest: One of the least looked after number in an option sheet is the number of traders who have placed their bets, which is captured in the Open Interest. This method can best be explained with an example. Nearly 84 per cent of the trades on National Stock Exchange take place in options. Various combinations of these three are used by traders to form a view of where the market is headed. One should be on the look out for the extremities in the market. First is by using the traded puts and call options during the day and the second is by using the open position of calls and puts.
Consider if a stock price is moving higher it should ideally be adding open interest in call options at the same time the option price should be increasing. Knowing them will also benefit the traders who prefers being in the cash market. However, professionals use the second one, which is using the ratio as a contrarian indicator. Armed with this basic information we shall now look at certain ratios which determine the possibility of a change in direction of the stock or market. But mainly it is on account of the sharp jump in percentage returns that is possible within a short period of time on account of increased volatility. Every market indices and stocks will have different average levels and extreme levels so it would be difficult to generalise. Within derivatives, which comprises of futures and options it is the latter that has captured traders attention. Delivery cash volume accounts for less than two per cent of the total traded volume during the day. On a standalone basis Open Interest means little on its own, but along with price and volume it gives a good indication of where the market is headed.
Prices of call options rises if market goes up and falls if it stays at the same level or falls. It will suffice to know some ratios and terms and their significance that normally foretell the direction of the stock. In essence it gives an idea of number of traders who are bearish as compared to those who are bullish. Generally movement in stocks starts in the option market which is, followed by futures and then the cash market. Similarly, a bottom is expected to be formed when open interest in put option reduces though price might continue to fall. The general belief in the market is that retail investor generally buys options and institutional or professional trader generally sells options, it is better to trade on the side of the professionals.
Preference for option is on account of the lower amount of money that is involved in buying a call or a put option. Though activity is concentrated in options, few traders, especially retail traders care to understand the instrument. The ratio helps in gauging the sentiment of the market or the stock. July but against popular belief the banking index led the overall market rally. Open interest rising along with volume and price is a strong bullish indicator while open interest and volume rising with price falling is strong bearish indicator. If one looks at the options chain to gauge, the person will see a huge sale of call options and a relatively lower sale of put options. That is open interest of calls begin to fall as price rises. If OI remains flat after substantial price rise OI it indicates that market is forming a top.
But post poor results, if company gives positive guidance for quarters ahead, the stock could surge despite posting poor results and cause a loss of money to the put buyer as call writers start covering their shorts. Similarly, rising OI but falling price indicates bearish trend. An outstanding buy or sell position on a stock or index futures or options contract. So, the buyer will probably be on the wrong side. If a company is expected to perform poorly prior to results the stock will fall and open interest rises. When OI does not rise much after a sharp fall in prices it indicates formation of a bottom and trend reversal.
Rising OI accompanied by rising price is indicative of bullish trend. ET provides the lowdown. What more can happen? Sometimes the buyer might see many calls being written and so, interpret that as meaning stock will face downside pressure and buy a put. Stock market initiates with an interest in derivatives will often come across the term open interest. But actually the seller had sold or written more calls knowing downside chances are greater or any possible upside will be capped.
Why can it mislead, especially during result season? Why is it important? High volumes along with high OI indicates greater hedger and trader participation on a stock futures or options counter. When writers feel a stock will rise, they sell puts and partly finance their own purchase of calls with premia received from buyers. Therefore, it is important to take an informed decision and trade with strict stop losses in place. Higher the OI, deeper the market.
This is a very useful tool in understanding, along with price data, whether a market has topped or bottomed, among other things. But often it could mislead those wet behind the ears. Conversely, high volumes and low OI means more speculative interest in a counter. Higher call OI than put OI will probably make the person inclined to buy a call, thinking that the stock will rise post result. If the stock is consistently moving higher, and short sellers no longer believe it will decline in price, they may decide to cut their losses and close out their short positions by purchasing the stock. As with most technical indicators, this tool is not meant to be used in isolation. You should not invest based solely on short interest; however, you can use it to help assess sentiment for a particular investment. Alternatively, if the price is moving higher or lower, but is not confirmed by an increase in open interest as well, that divergence could potentially be a signal that the bullish or bearish momentum may not continue.
Of course, the amount of short interest does not dictate how a stock will perform. What is short interest? It can be considered bearish for a stock to have high or rising short interest. High open interest can also indicate the potential for volatility. Meanwhile, volume would increase when you purchased the option and when you sold the option. An investor who is short will potentially profit if the price declines. Days to cover is short interest divided by average daily volume. For options investors, a useful tool to estimate volatility is open interest, which is the total number of options contracts that have not been exercised, closed out, or expired.

Open interest is particularly important for options traders, as it can help measure the potential future liquidity for a particular contract, as well as the potential volatility in the underlying asset. Doing your fundamental research is always the first key step, but when it comes to assessing market sentiment, you might also consider adding a few indicators to your investing toolkit. While you can get a general sense of investors who are bearish on the market using short interest as applied to an index, this measure is more commonly used for individual stocks. This could be viewed by some as a bullish signal. Note that a sudden increase, or decrease, in open interest does not necessarily suggest which direction the stock might move. Knowing what these interest indicators are and how they can help you evaluate your investments may help improve your outcomes. If you were to exercise that option one week from today, the contract would then be closed and open interest would decrease. Rather, investors can use short interest to quickly compare sentiment between stocks.
Tesla had the most short interest as a percentage of outstanding shares at this point last year. Rather, it may simply indicate there could be a change in the level of volatility. As with all investing endeavors, knowledge and information are essential. To evaluate open interest, you can compare a current level of open interest to previous levels, or you might assess current open interest relative to the volume of contracts traded. Thus, you might think of open interest as a measure of active and open positions, and volume as reflecting total trading activity. Stock markets are volatile and can fluctuate significantly in response to company, industry, political, regulatory, market, or economic developments.
Here, we focus on two technical indicators: short interest for stocks and open interest for options. Short interest is the number of shares of a particular stock that have been shorted. This can be important because it attempts to measure how long it may take to close out short positions and, consequently, the potential price impact of a short squeeze. In such an environment, it is more important than ever to do your research and use all of the tools at your disposal. This differs from volume in that open interest increases when a position is initiated and it decreases when the position is closed out; whereas volume will increase in both instances. Suppose there are 10 total outstanding shares of a hypothetical stock. In sum, short interest can serve as another piece of information to assess a potential investment. The short interest chart below demonstrates how short sellers have actually increased their short bets in 2017, despite a rallying stock market. Short sellers raised wagers despite an equity rally.
