In other words, if we represent, the standard deviation of the portfolio by sigma, and sigma s represents the standard deviation of the return from the risky asset. इसको हमने multiply किया, purportual

got 0.075 and that is the standard deviation of the entire portfolio so agar aap 37.5 percent total investment ka risky asset mein dalte hai to portfolio ke return ki standard deviation 0.075 hogi this is what it is saying and it's easy once you have calculated the standard deviation of the portfolio the next step and the final step is to put this equivalent to relate karna hai standard deviation ko expected rate of return se aur wo hum kaise kar sakte hai uskili hum ne kaha ke we have got this particular relationship jo ke w sigma s ko sigma ke saath mein relate karaha hai humare paas jo expected rate of return ki hum ne equation derived ki thi jis ko humne rate of line ke liye formula abhi bola tha us ye wo particular cheese hai isme agar aap isko w ke liye simplify karne aur w ki jaga pe aap is particular information se w ki jo value nick legi wo kya ho ghi it will be sigma over sigma s ye aap ko calculate kar ki yaha likha hua hai so w is simply the ratio of sigma to sigma s sigma is the portfolio ka standard deviation sigma s is the standard deviation of the return from the risky asset iss ki madad se humne iss particular equation mein w ki terms ko alaida kar liya to humare paas equation aai hi wali upar wali solve kar ke mein abhi thodir pele isko solve kiya tha aap ke liye iss bhi aap dek sakte ho that iss expected rate of return iss risk free return plus w times the risk premium which iss expected rate of return from the risky asset minus the risk free asset aap w ki value humne sigma over sigma s iss mein pluck kar di to abhi kya ho gha mein abhi aap ko bola tha ke what we are going to do is in the end saap se ahem baaj jo hai wo kya hai aap ne pele allocation karne hai ke humara jo portfolio hai uska composition kya ho gha ka matla bhai w ki value decide karne hai aur expected rate of return ki values humne nikali thi pele aap jab aap ke paas purportion pata chal kya expected rate of return pata chal kya poore portfolio ka phir aapne standard deviation nakaal ne standard deviation nakaal ne ke baat aapne standard deviation ko relate karna hai expected rate of return of the portfolio portfolio ke expected rate of return ka saath sigma ko sigma of the portfolio ko relate karna aur relate karne kli humne kya kya humne w ki jaga pe sigma over sigma s ki value ko pluck kar diya aur iss ko humne simplify kar aap to huma re paas simply kya agar w ki jaga pe humne ye value put ki to aap ke paas now you can put it aap sigma ke terms mein w ko nikaal ke sigma ke terms mein aapne expected rate of return of the portfolio equation ko likh sakte hain which is now expected rate of return of the portfolio is risk free asset ka return plus risk premium divided by sigma s multiplied by portfolio ka standard deviation sigma right now once you have done this it is important to investigate it further ke jab humne ye particular relationship nikali hai to iss mein ye jo information put aap hui bhi hai sigma se pehle plus ke baat that is the risk premium which is expected return rate of return from the risky asset minus risk free asset mein se jo aap ko park dono mein return way milegi usko hum risk free risky asset ke standard deviation se agar divide kar de to huma re paas ek ratio aati hai jis ko hum bolthe hai sharp ratio so sharp ratio ko hum reward to volatility ratio bhi bolthe hai aap reward to volatility ratio ka kya matlab hai ke jo numerator mein hai padawa ye aapka reward hai reward kisis ka hai risk lene ka reward right to reward aur uske niche aap variation ko divide kare ho ke kya variability aas sakte hai iss reward mein to humne sharp ratio ko define kya as the ratio between the reward which is the risk premium divided by risk lene ka premium divided by the total volatility and that is simply the standard deviation of the portfolio excess return aapne iss particular formula ko further deliberate kya iss kyo par gaur kya to aapko baase ek aur important aim concept dekhne ko mila hai i am going to explain this with an example with the help of an example suppose hum assume kare hain ke humara jo risk free asset hai uska return rf iss given as 6% aur risk ki asset ki standard deviation is 0.2 amare paase expected rate of return from the risk ki asset minus risk free asset yani ke risk premium aapko kya mila hai that is 0.08 iss saari information ko hum incorporate kar dey agar us formula mein jo ke humne develop kya tha jo ke relate kara hai show kara relationship between expected rate of return of the portfolio ko aur portfolio ki standard deviation ki relationship ko show karne wale formula mein humne ye information pluck ki to humare paase equation aajegi that is 0.06 plus 0.08 divided by 0.2 is 0.0.4 which you know times sigma so this particular line is this particular equation is a new equation jo ke trade line trade off line ko explain karehi karehi hai aur wo batati hai ke aap extra expected return market jo offer kari hai aapko har ek extra risk ke unit ko lene se aapko kya extra return milegi is particular equation se aapko ye andada hor hai so when we look at this particular equation you can see that ek additional unit of risk ko barhane se aapki expected return kitni increase karegi that can be given by this particular relationship which you can see so we've got another equation which previously humara jo equation humne define kya tha expected rate of return ko wo humara w ke terms mein tha wo proportion ke terms mein tha if you know how much proportion of the total investment you are going to invest in the risky asset to phir aap ek aur nahi equation ko bhi develop kar sakte hai jo ke relationship between risk and expected rate of return ko explain kar sakte hai aur uske liye aap sharp ratio ko define karengi aapni values jo hai wo incorporate karengiye to you will be able to come up with an equation explaining the relationship between risk and expected return to ye aapko bataye ghi ke ek additional extra unit of risk ke upar aap agar jaa rahe hain to phir aapko usse on average kya aapki return mein is aafa honi waal so this is another important aspect which we have to consider ya jo bhi aapki expert professional asset managers hain wo is particular information ko count for karke aapko portfolios suggest kate
