About the Topic

Every investor knows that portfolio balancing is beneficial, but why exactly? We state and prove a theorem and discuss related calculations. The key idea is the weighted geometric mean.

If a currency exchange deals in many currencies, how may a single list of relative values be found? We exhibit a method and its theory using M-matrices.

These two theorems suggest two different ways to establish currencies. We will compare various properties of these and other currencies.
