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 5 each if not upgraded).
* 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) or upgrade to use many features. A one month initial subscription for each device is included for free.

Does not work at all

Knowing the developer's other apps I am sure this one was pretty amazing, unfortunately it does not seem to work anymore: when opening the app, the following error message appears "web connection fail"...

Great for correlations

I use this app to compare the historic price of stocks and show how correlated they are (to each other and to indexes). It has great graphics.
