Consider the following data for the stock returns of companies R and K:

Stock	Beta	Standard deviation	Correlation with the market
R	0.80	25%	0.64
K	1.20	40%	0.60

The expected return on the market portfolio is 8% and the risk free rate is 2%. Assume both stocks are priced correctly according to the CAPM.

Among all the possible portfolios with expected return of 14% (which can include stocks R and K, the market portfolio, and the risk-free asset), find the portfolio that has the lowest standard deviation. Report the standard deviation of this portfolio in decimal form, rounded to 4 decimal places.
