Stock Pickers Digest, in its July, 2015, issue, refreshes its buy of Chemtrade Logistics Income Fund, recently $19.98. Stock Pickers said buy eight times from December, 2010, to April, 2015, at prices ranging from $14.04 to $21.38. Assuming an investment of $1,000 for each of the eight buys, the $8,000 position would now be worth $10,729. Chemtrade provides removal services for oil refineries and base metal processors, whose operations produce sulphur, acid and other byproducts. Chemtrade converts these substances into useful chemicals, such as sulphuric acid. In the three months ended March 31, 2015, the fund's revenue rose to $326-million from $266.1-million a year earlier, thanks to the contribution by General Chemical, which Chemtrade acquired at the end of January, 2014. Chemtrade's cash flow rose to $41.7-million in the first quarter of 2015 from $14.3-million a year earlier. The fund's long-term debt stands at $910.9-million, a high 64 per cent of its $1.4-billion market cap. Still, its steady cash flow will let Chemtrade pay down that debt, and its 10-cent monthly distribution is a high 6-per-cent annual yield. The stock remains a buy.
