📊 About Fair Value:
The Fair Value shown for each company is calculated using a Levered Discounted Cash Flow (DCF) model. This method estimates the intrinsic value of a stock by projecting future cash flows and discounting them back to present value, accounting for the company's debt structure. A positive percentage difference indicates the stock may be undervalued relative to this model, while a negative percentage suggests it may be overvalued. Fair value calculations are estimates and should be considered alongside other factors.
