On the aggressive side, Signet Jewelers (SIG) is a stock that can yield a good return at the cost of a higher risk, explains Azmath Rahiman, editor of Cabot Benjamin Graham Value Investor.

The company owns Kay Jewelers, Jared and Zales. The stock was already trading at a discount when the last quarterly results were released. Further, the stock had a 30% drop on the day the quarterly results were announced.

Signet has a variety of headwinds that have led to large-scale negative publicity, and ultimately, its depressed market valuation -- technical hiccups faced while outsourcing its in-house credit portfolio, an investigation on its credit practices by the Consumer Finance Protection Bureau and decreasing same-store sales.

Under the new leadership of Virginia Drosos, who is strategically focusing on long-term stability and growth, the company may continue to maintain its market leadership.

On stability, Signet is outsourcing its $1 billion prime credit portfolio, and on growth, and the company is focusing on its omnichannel (online) sales, including the acquisition of R2Net, which owns online diamond retailer JamesAllen.

Signet is the largest player in the diamond retail industry, and a strategic online push will deliver a robust result. In case of such a turnaround, the company has a significant upside potential.
