Can anyone show me how to answer this please?

A stock has beta of 2.0 and stock specific daily volatility of 0.04. Suppose that yesterday’s closing price was 95 and today the market goes up by 3%. What’s the probability of today’s closing price being at least 98?

  • $\begingroup$ If it is not homework, perhaps you want to share some more information, else why not just go with this? 1-pnorm((<end>-<start>)/100,mean=E(r_stock),sd=(<beta>*<vola>)) $\endgroup$
