What this transaction means for investors
Karellis has served as a director of the company's Board of Directors since May 2016. Clearly, he knows the business of Star Bulk Carriers inside and out. It is bullish that he's a buyer, especially since he acquired these shares by participating in a new share issuance as the company raised more capital. More shares usually have a downward effect on prices. He sees it differently.
Karellis's buying signals to investors that he believes the business momentum will continue. Why? Consider that there are many reasons an insider may sell a company's shares. One reason could be the need to raise cash to fund a large personal expense. Another reason could be for reasonable portfolio diversification unrelated to their outlook for the company. A third reason could be simply a bearish outlook on the company's future.
Yet there is only one reason for an insider to buy stock: they believe the share price will go up.
By that rule of thumb alone, Karellis's purchase of Star Bulk shares is a bullish signal. That signal is further bolstered by studies showing that, more often than not, an insider purchase predicts a higher share price 30 days later.
Plus, it's a bullish time for transoceanic shipping companies. The Iran war has disrupted the shipping business and sent rates rising. Star Bulk Carriers is one of the businesses enjoying the pricing leverage. Interestingly, it is also one of the few shippers permitted to go to Iran, because it has been delivering grain and other foodstuffs.
The company is in the midst of adding five new vessels and sees a strong market for dry bulk, not only in foodstuffs but also in increased coal shipments due to the closure of the Strait of Hormuz.
The combination of insider buying and a positive business outlook is a sign for investors to explore if Star Bulk is a stock to buy now.
