Someone is bullish on TSLA, and the reasons are shown in the chart: over the past few months, the price has been compressing within a massive weekly bullish pennant, and now it all comes down to whether it can reclaim the 50-week moving average; once it breaks the consolidation, he believes the characteristics of the whole chart will change, and that a more than 100% upside move is "absolutely possible".

A bullish pennant and a moving-average breakout, in essence, are about probability, not a promise. The direction is just one person’s opinion—your position sizing has to be your own.
