Ned Sherwood wants people to know that he is not an "activist investor" — despite his public criticism of Greek shipowner Angeliki Frangou.

He is not looking for a pile of money to walk away from his investment in her Navios Maritime Partners. Rather, the finance veteran of more than 40 years just wants something he said Frangou has been unwilling to give him: a chat.

"I'm not an activist investor and I don't want a payoff," Sherwood told TradeWinds.
