Interested in stock ideas but worried about their risk? For ideas on how to find low-risk stocks, we ran a screen you might be interested in.

We screened large-cap companies, with market caps above $10 billion, for those with low volatility, screening for those that have traded within 2% ranges every day over the last month.

We then screened for those trading at significant discounts to their Graham Number, potentially indicating that they are undervalued.

This number was created by the "godfather of value investing" Benjamin Graham, and calculates a stock's maximum fair value based off of its EPS and book value per share (BVPS). Stocks trading below their Graham Number may be undervalued.

Graham Number = SQRT(22.5 x TTM EPS x MRQ BVPS)
