As a US-flag tanker owner, Florida-based Overseas Shipholding Group (OSG) is not the most high-profile or heavily traded of shipping stocks, so a modest milestone reached on Thursday went largely unnoticed.

But the New York-listed owner nonetheless broke through the $3 per share barrier for the first time since July 2021. With further gains on Friday, the stock was trending toward its first close above $3 since November 2018.
