NEW YORK (TheStreet) -- Tesla Motors (TSLA) - Get Report stock is falling by 1.45% to $226.93 in late-morning trading on Tuesday, after UBS analysts cautioned that the electric vehicle manufacturer's upcoming Model 3 launch, on Thursday, could be a negative catalyst. 

The Model 3 will be contending with high expectations and growing competition, the firm wrote in a note, Barron's reports. Even if the launch goes well, the new model could weigh on sales of the currently available, more expensive Model S.

Additionally, Model 3 costs remain roughly $7,000 higher than an equivalent internal combustion engine (ICE) vehicle, and the 10-year cost of ownership is about $21,000 more than the equivalent ICE vehicle, UBS noted. 

Shares of Tesla dropped by 14% one month following the reveal of its Model X, the firm added, according to Barron's. 

UBS maintained its "sell" rating on shares, given headwinds regarding the long-term profitability of the Model 3, Tesla's storage business and the ultimate need to raise cash. 

Separately, TheStreet Ratings team rates the stock as a "sell" with a ratings score of D+.

Tesla Motors's weaknesses include its deteriorating net income, generally high debt management risk, disappointing return on equity, poor profit margins and feeble growth in its earnings per share.
