A public company Tesla running out of cash is just like a diver in a shallow pool holding his breath under the water and complains that he's running out of air.
It's just dramatic talk so people appreciate how hard he's training but there's a lot of air. Just move his head back and breathe the fresh air just above the water line!
It's the same talk by saying it's not possible to get cash from secondary common stock offerings because of dilution.
It may be true for other companies but not for Tesla.
I might miss some but Tesla has been issuing stocks multiple of times:
01/29/2010 IPO with 13,300,000 shares
05/21/2010 Secondary Common Stock Offering 2,300,000 shares
08/14/2015 Secondary Common Stock Offering 2,700,000 shares
05/25/2016 Secondary Common Stock Offering 1,395,348 shares
03/16/2017 Secondary Common Stock Offering 1,540,000 shares
Does that mean the stock would be diluted and its price would go down?
On the contrary: Despite repeated stock offerings, its stock price has trended up since 2010.
If you worry about Tesla running out of cash. It's just like worrying about the experienced diver in a pool would be running out of air! Don't worry about it!
By the way, TSLA is a growth stock.
And if you are worried about how its book will register profits from quarter to quarter, you are really choosing the wrong one!
It's just basic investing.
