The Uzbek company Quartz has turned around its finances over the first nine months of the year. After posting a loss in the comparable period previously, the firm is now reporting a profit. Revenue climbed 35 percent compared with the same stretch a year earlier. Growth of that pace suggests either stronger demand for its products or firmer pricing in the market. Results like these matter beyond the company itself, since industrial earnings give local investors a read on the health of the wider economy. A swing back into profit also gives management more room to invest as the final quarter approaches. The next set of numbers will show whether the improvement holds.
