Lesson 1: Tesla is flat Year-to-date. It will likely end quarter that way or very near too. And take a look at the swings within  – huge moves! It shows how misleading stats can be. 

TSLA crazy

Lesson 2: Markets are crazy and once the stock gets in motion it does not stop easily. I use 10EMA (grey line on the chart) to screen for such moves. Strength begets more strength and weakness begets more weakness. Do not fight the trend! 

Lesson 3: Take a look at the percentages. TSLA needed a 70% up move to erase the 42% down move. That is math for you. Hard and cruel. You always need more % on the up move to break-even.
