This South African gold producer saw short interest swell almost 36 percent to about 5.10 million shares, on top of a gain of more than 14 percent in the previous period. That mid-month figure was the greatest number of shares sold short in at least a year. But the days to cover remains less than two. AngloGold Ashanti posted a sixfold improvement in first-quarter earnings and named a new CEO in May. The company currently has a market capitalization of more than $6 billion and a dividend yield near 1.3 percent. The long-term earnings per share (EPS) growth forecast is about seven percent and the return on equity is almost 16 percent. The consensus recommendation of analysts who follow the stock that were surveyed by Thomson/First Call is to buy shares. The mean price target, or where analysts expect the share price to go, represents more than 48 percent potential upside, relative to the current share price, though that target is less than the 52-week high. The share price reached a multiyear low late last week and is still down almost 48 percent since the beginning of the year. The stock has underperformed larger competitors Barrick Gold and Newmont Mining, as well as the broader markets, over the past six months.

Harmony Gold Mining has a market cap of about $1.6 billion and a dividend yield near 2.6 percent. In early May the company reported a big earnings miss. The price-to-earnings (P/E) ratio is less than the industry average but the long-term earnings per share (EPS) growth forecast is less than five percent. The operating margin is less than the industry average as well. Again, the consensus recommendation of the analysts polled is to buy shares.

The share price is down about 58 percent year-to-date, and shares are trading near a multiyear low. Over the past six months, the stock has underperformed the likes of Barrick Gold and Kinross Gold, as well as the broader markets.
