The fire has little to do with it. The stock is down because earlier this week it was priced at 100x Tesla's earning estimates for next year, and implies a 30x growth in sales by 2020.

Simply put, while Tesla's fundamentals are strong, there's a bubble in the stock. Retail investors (e.g. us) have been excitedly buying it without taking a careful look at the stock, and several institutional investors have decided it's a good time to sell and reap the rewards (i.e. fleece the excitable retail investors).

Here's a CNN Money article about Bank of America's sudden bearward turn on Tesla: http://money.cnn.com/2013/10/01/investing/tesla-investors/in...

The Baird Capital report is a little more nuanced; it boils down to "Tesla have been kicking ass, and that's already priced into stock, so don't buy it now because everyone else is buying it": http://www.forbes.com/sites/chuckjones/2013/10/02/tesla-down...

Anyway, yes, this isn't anything wrong with Tesla, it's just a natural market correction.

When a stock is out of whack with its fundamentals, bad news is disproportionately likely to hurt, so it probably has a good deal to do with the fire.
