"Sustainable demand [is] the key question as shares [are] likely continue to de-rate," the bank said in a note. Goldman lowered the price target to $158 from $200, which would represent a 30% drop from Tesla's current levels based on Wednesday's close of $226.43.
"We believe that is the largest question for investors to underwrite at this point — what are sustainable demand levels for the Model S, Model X, and Model 3 — and how does that change with the introduction of Model Y production," Goldman Sachs analyst David Tamberrino said. "We believe a downward path for shares will resume as it becomes more clear that sustainable demand for the company's current products are below expectations."
Tesla shares are down more than 3% on Thursday. The stock is down 30% this year as the company continues to be mired in a myriad of controversies. Analysts and investors also continue to mull whether the company will need to raise more capital.
