The standard form of the Omega ratio is a non-convex function, but it is possible to optimize a transformed version using linear programming. [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 ...
Relative strength is a ratio of a stock price performance to a market average (index) performance. [1] It is used in technical analysis . It is not to be confused with relative strength index .
A ratio of two averages over the same domain is also always computed as the ratio of two integrals or sums. Yet more specifically, for a real function on an ordered set T {\displaystyle T} (e.g. a price curve), one may consider that function's gradient g {\displaystyle g} , or some weighted variant thereof.
The index can also be charted over time and used as a kind of technical analysis indicator, to show stocks going into ulcer-forming territory (for one's chosen time-frame), or to compare volatility in different stocks. [4] As with the Sharpe Ratio, a higher value of UPI is better than a lower value (investors prefer more return for less risk).
Change in Asset Turnover ratio (1 point if it is higher in the current year compared to the previous one, 0 otherwise); Some adjustments that were done in calculation of the required financial ratios are discussed in the original paper. [2] The score is calculated based on the data from financial statement of a company.
Modigliani risk-adjusted return is defined as follows: Let be the excess return of the portfolio (i.e., above the risk-free rate) for some time period : . where is the portfolio return for time period and is the risk-free rate for time period .

The Ohlson O-Score is the result of a 9-factor linear combination of coefficient-weighted business ratios which are readily obtained or derived from the standard periodic financial disclosure statements provided by publicly traded corporations.
