In March Series OI, the 7500 strike price is indicating we may see an upside which no one is expecting - just an educated guess - no indicator in market as of now - most probable scenario is hitting 7300 level and revert back - and market closing below 7200 in series
But then we can very well show chart from 2003 or 1990. Since 2008 GDP has grown ... It can fall, but over long term Sensex growth is approx GDP + inflation.
And not every fall will be = 2008 size . 10 20 30 % falls happened in previous bull runs too ...
