WebThe result is also referred to as the tangency portfolio, as it is the portfolio for which the capital market line is tangent to the efficient frontier. This is a convex optimization problem after making a certain variable substitution. See Cornuejols and Tutuncu (2006) for more. WebMay 26, 2011 · The vector of optimal weights w is easily calculated from the vector of auxiliary variables z. For example, w* for the minimum-variance portfolio is w* = z i * /sum ( z i * ), and z* =V −11. Optimal weights for the tangent portfolio in the rp−p std plane are obtained by using returns in the calculation of z*, that is z* =V −1r. can you text on a fitbit
