The Financial Post reports in its Saturday edition that for Canadian stock pickers, success in 2023 hinged almost entirely on whether they held Shopify. A Bloomberg dispatch to the Post says that was the finding from an S&P Global analysis of active fund managers in Canada last year, when the e-commerce company's 119-per-cent surge was the single biggest contributor to the S&P/TSX Composite Index's total return of 12 per cent. In short, if a fund manager picked Shopify, they were more likely to beat the benchmark for Canadian equities. Most of the 71 actively managed Canadian equity funds did not, leading to 85 per cent of those tracked by S&P Global underperforming for the year, according to the S&P Indices Versus Active Canada Scorecard, released Thursday. On the other side of the ledger, fertilizer producer Nutrien was the biggest drag on the S&P/TSX composite last year.
