Let's break down this supposed correlation between Tesla and the price of oil.
Near-term demand: the price of oil adds to the TCO of rival ICE vehicles. So as the price of oil increases Tesla's products look more attractive than alternative ICE. Thus, demand is correlated with oil price. However, current demand exceeds supply, and excess unmet demand is of little value to Tesla at this point. Thus, the price of oild must fall quite a bit to create a demand constraint on Tesla. I think Tesla has ample safety with oil above $50 barrel. Demand is based more on performance than full efficiency. I suspect most buyers would still be interest in Tesla even if oil was at parity with electricity, so even $25 per barrel would not induce performance buyers to reject a Tesla. So near-term demand is not critically threatened by low oil prices, nor would sales increase if oil were to jump to $150 a barrel. Being supply constrained means that Tesla's sales are uncorrelated with the price of oil.
Near-term Supply: the price of oil adds to the cost of producing and distributing Tesla's products. A reduction in oil prices should reduce transportation cost. So battery cells shipped from Japan cost less, other inputs shipped to Fremont cost less, plastic and other petroleum products used in production cost less, and shipping finish goods to customers around the globe cost less. So an oil price reduction has a deflationary impact on the cost of goods sold, which improves profitability.
Long-term Impact: if Tesla is successful in disrupting the dominance of ICE in the automotive industry, this will lead to a reduction in demand for oil. When EVs crush oil demand, the success of Tesla will correspond to a decline in oil. Thus, long-term Tesla and the price of oil may actually come to be negatively correlated.
In sum, my view is that currect low oil prices are benficial for Tesla, increasing profitability with no loss of sales, and we should not expect oil and Tesla to be positively correlated now or in the future. In market participants want to believe there is a positive correlation and trade accordingly, they do so to their own peril. Long-term Tesla investors should be prepared to invest contrary to such an uncritical view.
