Musk says investors should be in it for the long run.

'If you care about the long-term, Tesla, I think the stock is a good price, ' he told CNBC. 'If you look at the short term, it is less clear.'

Musk made the remarks to CNBC on Thursday as he announced that Nevada was the location chosen for Tesla's gigantic lithium-ion battery plant, which is expected to bring down the cost of Tesla Model 3 by , 800.

The billion facility, called the 'gigafactory, ' is expected to bring 6, 500 jobs to the state and 0 billion in economic benefits, according to CNBC. In return, the state offered Tesla up to .3 billion in tax breaks.

Also vying for the plant had been Arizona, California, New Mexico and Texas.

'The biggest single factor was time to completion, because unless the gigafactory is ready when we need to produce the mass-market affordable electric car, the vehicle factory will be stalled — so time to execution was extremely important, ' Musk told CNBC.

'Nevada was in the lead, I would say number one, in time to execution.'

The factory is expected to open by 2017.
