Investors in Ford Motor Co. (F - Get Report)  should prepare for a rough road ahead in 2019, according to a note from analysts at JPMorgan Chase. 

The firm noted that the company's performance during the Detroit Auto show last week didn't leave it very optimistic after Ford cited uncertainty around Brexit, currencies, commodities and the U.S. policy environment as a reason for not providing explicit financial guidance. 

As a result, JpMorgan trimmed its full-year 2019 global production forecast to 5.87 million units from its previous view of 5.97 million vehicles. It also lowered its 2020 forecast to 5.87 million units from its previous view of 6.2 million units. 

The company is being hurt by soft demand in Europe and especially China, where JPMorgan said the company's biggest shortfall between guidance and reality exists. 

This new forecast forced the firm to also lower Ford's EPS estimate for 2019 and 2020 to $1.25 per share and $1.55 per share, respectively, from its previous view of $1.35 per share and $1.60.

JPMorgan also lowered its price target estimate to $12 per share from $13 per share. 

Shares fell Wednesday by 1.9% to $8.34.

Ford is scheduled to report fourth-quarter earning after the closing bell Wednesday with analysts expecting the company to earn 32 cents per share on revenue of $38.66 billion, a 6.4% year-over-year decline.
