Is it possible to buy only one share from a Tesla stock and if yes what is the price per share?

Yes, you can purchase only one share of Tesla stock. You buy a single share for any stock you want.

All you need is a web brokerage account. And, depending on what platform you use, you can also purchase a fraction of a share of Tesla stock (but that's another explanation for a different question!).

At the time of this writing, Tesla shares are trading a little bit above $700.
