( TSLA ) shares, which closed at $377.64 today, are trading just below their 52-week high. A move above $387 would mark a new all-time high for the stock. That means no overhead price resistance, only the potential for blue skies above. Here is a monthly chart (log scale, click to enlarge) that goes back to Tesla's IPO in 2010. It shows the stock's full trading history, including the breakout move from $40 to $290 in 2013 - 2014. The weekly chart below shows Tesla's recent breakout (from a long 3-year trading range) above $300 and the run up to its highs above $386. If TSLA can hold these gains and advance an additional 4%, the stock will be trading at a new all-time high. $387 is the magic number here.
