Fiat Chrysler fell as much as 5.1% Tuesday after Goldman Sachs' coverage on the stock with a "sell" rating.

Fiat Chrysler traded at $13.68 per share as of 11.25 a.m. ET, reaching its lowest level since mid-June.

This is despite markets hitting record highs over the last several trading days, says Business Insider.

The automaker also faces a larger climb than its peers to reach Europe's 2021 CO2 compliancy levels.
