Using BellCurve is quite easy. Enter a ticker, select a target price, and select a time frame and let BellCurve handle everything else.

Behind the scenes, BellCurve calculates the historical daily prices moves, summarizes potential moves using the normal and lognormal distributions, and then estimates the probability of target moves.

BellCurve exists because many public stock market investors require context to assist in their investing activity. Some investors want to time their entry or exit trades in order to place a position with a good chance of succeeding. Other investors analyze options and would like to know the potential range of stock price movements before implementing a trading strategy. In each case, context for potential price movements helps investors make intelligent decisions.
