The GF Value represents the intrinsic value of a stock, determined using GuruFocus' proprietary methodology. The GF Value Line on our stock Summary page provides an estimate of the stock’s fair-trading value.
To calculate this value, GuruFocus follows these steps:
We analyze historical correlations between the stock price and key business performance metrics, such as revenue, earnings, cash flow, and book value.
We identify the metrics that have the strongest historical correlation with the stock price and determine the historical multiples at which the stock has traded relative to these metrics.
Using these historical multiples as a reference, we estimate the stock's fair value while accounting for future business growth. Adjustments may be made based on the company’s past returns and growth trends.
GuruFocus believes that the GF Value Line represents the fair value at which a stock should trade. Stock prices typically fluctuate around this line. If a stock’s price is significantly above the GF Value Line, it is considered overvalued, and its future returns are likely to be lower. Conversely, if the stock price is significantly below the GF Value Line, its future returns are likely to be higher.
