The Globe and Mail attempts to identify overleveraged, overvalued stocks with shrinking earnings in its Thursday, March 31, edition. The Globe's guest columnist Ian Tam writes in the Number Cruncher column that he thought it might be wise to ponder Canadian-listed stocks that, for a combination of reasons, need double-checking whether they still belong in portfolios. Although not foolish investments, per se, Mr. Tam says these stocks exhibit a combination of fundamental characteristics that are generally unappealing to the conservative long-only investor. The stocks come from the Morningstar CPMS Canadian Dangerous strategy, which ranks stocks on debt-to-equity (higher figures preferred) and cash flow to debt (lower figures preferred), latest earnings surprise (a surprise to the downside preferred), three-month earnings-per-share estimate revisions (negative or downward revisions preferred). Mr. Tam says for conservative investors looking for more reasonable returns consistently over time will not find those stocks on the following qualifiers list. Mr. Tam's risky picks are ShawCor, Charlotte's Web Holdings, Lion Electric, First Majestic Silver, Polaris Infrastructure and Tilray.
