Vistra Energy Corp. (VST) shares plunged 12.16% in Friday's trading session following Goldman Sachs' initiation of coverage on the stock with a Neutral rating. The prominent investment bank also set a price target of $134 for Vistra, adding pressure to the energy company's stock performance.

The sharp decline in Vistra's stock price appears to be a direct response to Goldman Sachs' cautious stance, which contrasts with the generally more optimistic view held by other analysts. According to FactSet data, Vistra currently maintains an average rating of overweight among analysts, with a mean price target of $179.04. The discrepancy between Goldman Sachs' price target and the consensus target likely contributed to the significant sell-off.

This development may have caught investors off guard, potentially triggering a reassessment of Vistra's near-term prospects. As the market digests this new rating from a influential financial institution, it remains to be seen how other analysts and investors will react in the coming days. The energy sector's overall performance and company-specific factors will likely play crucial roles in determining Vistra's stock trajectory moving forward.
