Stocks & Options Pro is the most advanced Windows Phone application for managing both stock and option investments. It currently enjoys a 4.5/5.0 star rating in Windows Phone Marketplace. For stocks, the application features a watchlist and a portfolio. The watchlist is used to monitor stocks, their prices and latest headline news. For each stock in the portfolio, a user can record various purchases, including dividend reinvestment, and see the current market value, cost basis and unrealized gain (or loss) for each transaction, as well as the long-term or short-term capital gain or loss should the stock be sold. Holdings in the stock portfolio can be visualized using one of the four views: summary, performance, pie chart or bar chart, or be displayed on the app’s Live Tile. The application’s main strength is its advanced options features and no other mobile application today offers anything comparable. Similar to stocks, the app features a watchlist to monitor the prices of calls and puts for different strikes and expirations, as well as a portfolio to manage both simple call/put or advanced (such as strangle, straddle, spreads, multi-leg, etc…) option contracts. When establishing an option position, the app provides guidance and analyzes the contract’s potential profits versus risks. This also serves to determine the optimum number of contracts. As the option contract approaches expiration, the option's time value premium dissipates. The price of the underlying stock may also move in un-anticipated directions. The app looks at all these data points and offers follow-up suggestions to extract additional return, lock in profits or reduce losses.
