Trying to guess where Tesla is heading is a fools game. There have been some amazing companies who's Share Price has tracked down over the years whilst their fundamentals keep hitting line drives out of the park.
Average revenue growth over the last 5 years is 71.55%, and average Gross Margin growth rate over the same period is 28.97%.
Yes Tesla is facing headwinds, with their Shanghai Gigafactory suffering from lengthy closures due to China's strict lockdowns, but when you have a business who is closing down pre-orders for products because demand is at insane levels, it means it's customers don't care, the cars are worth the wait.
If you are looking to buy Tesla stock, instead of trying to guess the bottom, I suggest going with the old fashioned but tried and tested dollar-cost-averaging or value-averaging methods. Proven to be effective in volatile times and when the stock is tracking downwards.
