Mizuho analyst John Roberts lowered the firm's price target on Huntsman to $13 from $14 and keeps a Neutral rating on the shares. The firm lowered price targets for most of its basic chemical coverage and upped targets for four technology materials stocks as part of a Q2 earnings preview. Oil futures have declined recently, reducing the natural gas advantage expectations for many basic chemicals, and the continued downstream investment in advanced compute should lengthen the duration of the tech materials' strength, the analyst tells investors in a research note.
