After a long, steep rise* to a market cap well in excess of several carmakers with well-established franchises and less unpredictably flammable technology, TSLA took a hit when a video of a burning Model S went viral on Youtube. A more recent fall in the stock coincided with an InteractiveBrokers margin hike**.
A downward-sloping pitchfork dating to ~9th Oct now looks confirmed (eg by support at the ML, a zoom through the ML, and finally resistance at the ML***). An entry may present itself within the next few hours: short at 167.5, stop at 171.3 (or just above ML if you like to live dangerously). Of course, if TSLA makes it back above the ML (~$170) all bets are off...
This is my first 'idea' & I just made it up. So comments welcome & good luck! :)
