The Successful Investor, in the February, 2020, issue, says buy ShawCor Ltd., recently $12. The Investor previously said buy 35 times from September, 1995, to August, 2019, at prices ranging from $10 to $59 (the stock split 3 for 1 in May, 1998). Assuming a $1,000 investment for each of the 35 buys, the $35,000 position is now worth $24,132. ShawCor makes sealants and coatings that prevent rust on oil and gas pipelines. It also makes industrial products such as electrical wire. As well, about a year ago, it bought ZCL Composites Inc., which makes underground storage tanks for fuel and waste water. Given that weak oil and gas prices are hindering demand for ShawCor's pipeline-coating services, the Investor applauds the company's efforts to expand beyond the energy industry. It is optimistic that ShawCor will be able to maintain its 15-cent quarterly dividend despite the high yield of 5 per cent. Buy.
