JPMorgan analyst Ryan Brinkman downgraded Camping World Holdings to Neutral from Overweight and lowered his price target for the shares to $11 from $19. The company's deterioration in profitability that began to accelerate in recent quarters was forecast by management yesterday to in fact worsen further in the second half of 2019, Brinkman tells investors in a post-earnings research note. Further, the recreational vehicle environment has "clearly softened," with demand lower, but the relatively modest deterioration in unit volume is resulting in out-sized declines in EBITDA, says the analyst.
