Dorian LPG (LPG) was Smart Insider's stock pick of the week after President and Chief Executive John Hadjipateras acquired $410,000 worth of company shares at $27.30 apiece on Jan. 7.

Hadjipateras' last buy was in April, which proved "very timely", Smart Insider said in a Tuesday note.

The CEO has made 12 previous purchases, while his combined stake is roughly 11% of the company and "likely feels no pressure to add", according to the note.

The recent buy is an "interesting" purchase, since the CEO bought at a 50% higher price than his April buy, Smart Insider said.

Smart Insider ranked the stock to +1, or strong positive signal, on Jan. 12.
