Tesla Motors earnings: 5 catalysts to watch

Tesla Motors posts fourth quarter and 2013 full-year earnings after the markets close Wednesday. Assuming the California-based electric car company reports numbers that are roughly in line with expectations, the focus will be on the conference call CEO Elon Musk holds with analysts.

On that call there are the five topics to listen for, each of which has the potential to push Tesla shares higher:

2014 Model production

Previously, Musk has said Tesla hopes to produce 800 Model S premium electric sedans every week by the end of 2014. But will Tesla have the greater supply of lithium-ion batteries needed for a higher weekly production rate?

'Giga factory' plans

For the last nine months, Musk has talked about constructing a "giga factory." If built, this would be the world's biggest battery plant and would dramatically increase production of lithium-ion battery cells. But will Musk give a more concrete time frame for naming the location and construction of that factory? If so, it could give Tesla shares a pop.

China sales ramp up

Tesla has been taking Model S orders in China, and the official delivery of the first Tesla will happen sometime in the next couple of months.

So does Musk have a sense for how quickly sales in China will ramp up? If he puts out a particularly bullish forecast, Tesla investors will be smiling.

Model X ready to roll?

As impressive as the Model S has been, many are wondering if the Model X CUV (crossover utility vehicle) will be a second hit for Tesla.

First deliveries of the vehicle, which is designed to combine features of an estate car and a passenger vehicle, are scheduled for later this year and there's no indication Tesla is running into delays.

Analysts will focus on how Musk portrays initial demand for the Model X and final plans for its roll out.

Expanding the 'supercharger' network

Tesla "supercharger" stations allow its car users to charge up for free. Now that the station network extends from coast to coast in the U.S., the focus is on how quickly Tesla will add other stations around the U.S. and Canada.

This network is a critical but often overlooked aspect in the growth of Model S sales outside of its sales base in California.
