There are lows from November 2013 and January 2014 where the PSR was lower at 8.5 and 8.7. Those numbers are adjusted after Tesla reports and are back-dated, so you'd have to know what sales are going to be (probably up 20% or more at least) to know what the current PSR is going to be, when we look back at it from the future.
Either way, TSLA is down 87 pts or 30% from the high when it hit the low today at 204.27 and perhaps the shorts are covering here, which would explain the bounce. But what is interesting is that the "key levels of support" that I have found nailed the bottom of the decline today and have provided very useful references for price action for quite some time. 204.5 and 198.3 are the "key levels" of support and 229 - 237 are the key levels of resistance where you will find sellers.
Any positive news on the Model-X and Tesla could move up to the 240-260 area. I'm a buyer on weakness to key levels where the price range contracts. Stay tuned.
