The Successful Investor, in the June, 2016, issue, says hold Pengrowth Energy Corp., recently $2.08. The Investor said buy 19 times from August, 2005, to September, 2015, at prices ranging from $1.71 to $26. Assuming a $1,000 investment for each of the 19 buys, the $19,000 position is now worth $5,112. Pengrowth has more than tripled from its January low of just 66 cents. This is likely because prominent investor Seymour Schulich recently bought 16.6 per cent of the company's shares, making him its largest shareholder. Separately, Pengrowth continues to unload non-core assets in order to focus on its Lindbergh oil sands project. Proceeds from the asset sales are being used to repay long-term debt, which is now $1.7-billion, or about 1.5 times market cap. Another effect of the sales has been to whittle Pengrowth's production down to 62,056 barrels of oil equivalent a day in the first quarter of 2016 from 67,934 barrels a day a year earlier. The lower production, combined with weaker oil and gas prices, reduced cash flow per share to 20 cents from 21 cents. Pengrowth remains a hold.
