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 ...
For example, the delta of an option is the value an option changes due to a $1 move in the underlying commodity or equity/stock. See Risk factor (finance) § Financial risks for the market . To calculate 'impact of prices' the formula is: Impact of prices = option delta × price move; so if the price moves $100 and the option's delta is 0.05% ...

The downside is a complete loss of the stock investment, assuming the stock goes to zero, offset by the premium received. The covered call leaves you open to a significant loss, if the stock falls.
The naked put is a neutral-to-bullish strategy and consists of selling a put option against a stock. The naked put profit/loss profile is similar to the covered call (see above) profit/loss profile. The naked put generally requires less in brokerage fees and commissions than the covered call.
By selling the option early in that situation, the trader can realise an immediate profit. Alternatively, the trader can exercise the option – for example, if there is no secondary market for the options – and then sell the stock, realising a profit. A trader would make a profit if the spot price of the shares rises by more than the premium.
Options are a short-term vehicle whose price depends on the price of the underlying stock, so the option is a derivative of the stock. If the stock moves unfavorably in the short term, it can ...
where E is the expectation operator, u is a known utility function (which applies both to consumption and to the terminal wealth, or bequest, W T), ε parameterizes the desired level of bequest, ρ is the subjective discount rate, and is a constant which expresses the investor's risk aversion: the higher the gamma, the more reluctance to own ...
