Greek boxship owner Performance Shipping has been told to boost its stock price performance by the Nasdaq exchange in the US.

The former Diana Containerships said it had received written notice stating its stock had been trading below the minimum $1 requirement for 30 consecutive business days.

It closed at $0.97 on Tuesday.

The shipowner now has 180 days to regain compliance - ie bring the price back above the $1 mark for 10 straight days.
