NEW YORK (TheStreet) --Shares of Gold Fields (GFI) are gaining by 5.48% to $3.85 on Tuesday afternoon, as the spike in the price of gold drives some mining and related stocks into the green today.

The price of the precious metal jumped following comments from Fed chairwoman Janet Yellen, who noted that the central bank is going to take a more cautious approach when it comes to interest rate hikes.

Gold for June delivery is up by 1.54% to $1,240.80 per ounce on the COMEX this afternoon.

Speaking at The Economic Club of New York, Yellen said that the Fed is going to rely on bond purchases if the economy falls, MarketWatch reports.

Gold Fields is a Johannesburg, South Africa-based gold producer that has eight operating mines in Australia, Ghana, Peru and South Africa.

Separately, TheStreet Ratings has set a "sell" rating and a score of D on Gold Fields stock. This is driven by multiple weaknesses, which TheStreet Ratings believes should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks it covers. The company's weaknesses can be seen in multiple areas, such as its deteriorating net income, disappointing return on equity, generally disappointing historical performance in the stock itself and feeble growth in its earnings per share.

TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author.
