[4] To begin with, Kapsos et al. show that the Omega ratio of a portfolio is: = [() +] + The optimization problem that maximizes the Omega ratio is given by: [() +], (), =, The objective function is non-convex, so several ...

Portfolio optimization often takes place in two stages: optimizing weights of asset classes to hold, and optimizing weights of assets within the same asset class. An example of the former would be choosing the proportions placed in equities versus bonds, while an example of the latter would be choosing the proportions of the stock sub-portfolio ...
For example, if a stock has a YTD return of 8%, it means that from January 1 of the current year to the present date, the stock has appreciated by 8%. Another example: if a property has a fiscal year-end of March 31, 2009, and the YTD rental income as of June 30, 2008, is $1,000, this indicates that the property earned $1,000 in rental income ...

The model results in a strategy's exposures to asset classes or other factors, interpreted as a measure of a fund or portfolio manager's investment style .
