Stock Position

About this app

Stock Position downloads and analyzes market price data of a portfolio of stock assets (NYSE or NASDAQ). It lists the current market price of the individual assets and the portfolio, graphs the price (over the past 10 years) of individual assets and the portfolio, compares the price (over time) to any listed market factor, correlates the rate of return to determine the beta value for the individual assets and the portfolio, and displays the standard deviation and CAPM expected return of the individual assets and the portfolio. * 8 portfolios of 40 assets each (or 1 portfolio of 5 assets if no subscription). * quick display of asset and portfolio current values and gain/loss (many values are real time) * use asset proxies (surrogates) to track intra-day asset values * weekly beta calculated from any start/end dates IMPORTANT NOTE: Although initially free, Stock Position requires an In App Purchase subscription (non-renewing) to use many features. A one month initial subscription for each device is included for free.

Bug fixes

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
