10 Year. Morningstar rated the Global Technology Fund among 196, 196, 186 and 144 Technology funds for the overall rating and the 3-, 5-, and 10-year periods (as applicable) ending 02/28/2017, respectively.
Geometrically an eigenvector, corresponding to a real nonzero eigenvalue, points in a direction that is stretched by the transformation and the eigenvalue is the factor by which it is stretched. If the eigenvalue is negative, the direction is reversed.
Theorem SMEE Similar Matrices have Equal Eigenvalues. Suppose $A$ and $B$ are similar matrices. Then the characteristic polynomials of $A$ and $B$ are equal, that is, $\charpoly{A}{x}=\charpoly{B}{x}$. Proof. So similar matrices not only have the same set of eigenvalues, the algebraic multiplicities of these eigenvalues will also be the same.
