We didn't get anywhere near that level with the 12% S&P correction in February. It would take more than that, perhaps twice that correction. Possible but not at all likely.
Yeah I was surprised we didn't break 300 then. I believe TSLA was a bit fortunate at the time to have a relatively high price when the correction happened.
I look at it this way, examining the local highs and lows of TSLAs price movements when it had major swings of volatility in the span of a few months:
09/30/2013 - 193.37
11/26/2013 - 120.50
37.7% loss
03/04/2014 - 254.84
05/08/2014 - 178.59
30.0% loss
09/04/2014 - 286.04
03/27/2015 - 185.00
35.3% loss
07/20/2015 - 282.26
02/10/2016 - 143.67
49.1% loss
04/06/2016 - 265.42
11/14/2016 - 181.45 (Spiegel bottom)
31.6% loss
06/23/2017 - 383.45
11/02/2017 - 299.26
22.0% loss
02/26/2018 - 357.42

Perhaps TSLA is more mature now and less likely to have quite as severe price swings. I wouldn't count on that, though. Ever since the infamous 11/14/2016 Spiegel bottom, things have behaved quite a bit different.
A price of 245.00 would be a 36.1% drop from 383.45, and a 31.5% drop from 357.42. Judging from past "normal" periods of volatility, that wouldn't be terribly surprising to me.
That said, I still wouldn't think you are crazy if you think 305-310 is a current bottom. But I definitely wouldn't be terribly sure of it.
