Jefferies analyst Randy Giveans upgraded Safe Bulkers to Buy from Hold with an unchanged price target of $3.50. The stock has traded down recently with capesize rates amid Australian iron ore supply disruptions, but Capesizes make up only four of Safe Bulkers' 41-vessel fleet, Giveans tells investors in a research note. The analyst points out that smaller asset class spot rates, time charter rates, and asset values "remain firm." He thinks the shares, currently trading at a 20% discount to estimated net asset value, are undervalued. Safe Bulkers shares should perform well as rates improve in the coming weeks/months, says Giveans.
