Despite slightly weaker than expected guidance and some questionable "market research" published last week, shares of XPO Logistics have long-term value, Barclays analyst Brandon Oglenski tells investors in a research note titled "Real Work on a Real Company." The analyst says he found last week's short report on the company to have "numerous inaccuracies and likely false conclusions." XPO's cash flow generally matches reported earnings and growth is "clearly evident in recent results," says Oglenski. He finds XPO's shares to offer "significant long-term upside from current levels." The analyst keeps an Overweight rating on the stock with a $100 price target. XPO closed Friday up $7.23, or 16%, to $51.55.
