How To Read Open Interest, Put Call Ratio, And Volatility

In: Stock Market

1 Apr 2008

Open Interest is an important indicator that can help one in ascertaining the flow of funds.

  1. If the open interest rises with rise in price it is a bullish indication.
  2. If open interest rises and prices fall it is a bearish indication.
  3. If open interest falls and prices rise it is a sign of short covering by bears.
  4. If open interest falls and prices also fall it is a sign of profit booking by bulls or liquidation of positions.

Put Call Ratio is an important indicator that can help one in gauging the future direction of the market.

  1. If the Put call ratio rises then there is hope of higher prices in the near future.
  2. If the Put call ratio falls it is a sign of weakness in the market.
  3. Generally put call ratio is read along with volatility.
  4. PCR can be calculated for Open Interest/positions or no of puts and calls traded.
  5. Historically – 1.06 -2.00 is bullish. Above 2 and below 1.06 one may expect a sharp fall.

There are two types of Volatility – historic volatility and implied volatility. Historic volatility is based on historic prices of the futures and implied volatility is based on the volatility calculated from options i.e. volatility implied by premiums in options.

  1. If volatility rises and PCR falls, it has bearish implications.
  2. If volatility falls and PCR rises, it has bullish implications.

i want to now about open interest and pricing relationship and how do i come to a point of decision to purchase or sell a stock. also i want to know the relationship betweel future and option. for example one told me that when large no. of put option is there in a stock the price should go up because of hedging. that means in the future markets the stock must be purchased. is it so? pl. show me the light if u can.

Hey angsuman,

But I am not that good in F&O. I suggest you to ask your broker. That question can be answered only by someone who are active in F&O.

Hi Mahesh,

I am little confused between open interest based ratio and trade volume. If we consider the trade volume to conclude on the market sentiment, then we are considering a contract, where there is a trader taking an opposite position which nullifies the effect. As for open interest, when there is nobody to close down the position, wont that confirm the fact that the market sentiments are shared by most people equally?

Kindly mail me the ppt too..
Thanks in advance!

Where can I get weekly historical spx index data as well as weekly spx options open interest and volume going all the way back to their start in the nineties? To make this task harder I want to find a source much cheaper than the CBOE!
