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 ...
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.
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 .
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.
If the stock does not currently pay a dividend, like many growth stocks, more general versions of the discounted dividend model must be used to value the stock. One common technique is to assume that the Modigliani–Miller hypothesis of dividend irrelevance is true, and therefore replace the stock's dividend D with E earnings per share ...

These equations show that the stock return is influenced by the market (beta), has a firm specific expected value (alpha) and firm-specific unexpected component (residual). Each stock's performance is in relation to the performance of a market index (such as the All Ordinaries). Security analysts often use the SIM for such functions as ...
A valuation multiple [1] is simply an expression of market value of an asset relative to a key statistic that is assumed to relate to that value. To be useful, that statistic – whether earnings, cash flow or some other measure – must bear a logical relationship to the market value observed; to be seen, in fact, as the driver of that market value.
