    Compute Benjamin Graham's fair-value ceiling (sqrt(22.5 * EPS * book value per share)) for a US-listed ticker, and the margin of safety against its current price. Looks up EPS, book value per share, and price from SEC EDGAR + market data automatically -- just pass a ticker. You can also pass eps/bvps/price directly to compute it for a hypothetical company with no ticker.
