I just thought of a way to think of pricing for high-growth stocks. (Or any stock, really.) We could attach a plus-or-minus figure to the current or predicted price, to give a margin of error. That range could be the differences between the current price and the high and low during a time period, or could be based on some other calculation. The range could be interpreted as risk and/or volatility and/or uncertainty.

The range could be expressed in absolute figures or as percentages. For instance, you could give a share price as 103 +/- 18%. The plus and minus percentages don’t have to be equal.
