Chris Lau, Kapitall: A rebound in gold prices doesn't necessarily mean it's time to start buying up gold stocks. 2013 was a horrible year for gold. As the markets rose by double digits, gold fell by an equal amount. But this year began with a rebound in gold stocks, which in turn has boosted the share price of gold mining stocks. A number of factors – including rising development and acquisition costs – had already strained balance sheets across the sector. Still, it might be time to look at gold miners again. Gold at $1200 Gold prices are at levels far below the $1600 range seen in 2013. Any rebound in gold prices this year would boost gold miners directly: However investors should not count on rising gold prices alone to justify a position. It is notoriously difficult to forecast future prices. It is also difficult for investors to know when the government will end or reduce quantitative easing at significant levels.

Goldcorp met its 2013 gold production forecast in Q4. For the quarter, it produced 767.7K oz. of gold. And for fiscal 2014, gold production is forecast to grow by up to 18%. Meanwhile production costs are expected to fall. Newmont Mining (NEM) could improve results by adding to low-cost operations this year. Investors should monitor for better free cash flow as 2014 progresses. In a similar vein, Kinross Gold (KGC) may report smaller write-downs in light of the low gold prices. Its reserves already assume a price of $1200 per oz. So do you see investing opportunities in these gold mining stocks? Use the list below to begin your analysis.
