I don't think it'll take something that long term for Tesla to get the valuation it deserves. I see there being 2 significant re-valuation events for TSLA over the next 5 years.
The first is the re-evaluation that will be coming in the next 1-2 quarters due to margin expansion and earnings expansion that firmly puts to rest Tesla peak earnings and demand worries. We are on the cusp of FSD revenue recognition along with what I think will be a material increase FSD subscription purchase rates going forward. Especially new orders. Then we have Austin/Berlin reaching mass production. Both seem to be likely to average 5000/week for Q1 which will dramatically increase gross margins due to amortization/depreciation. Lastly, the IRA benefits will go into effect in Q1 which by estimates, will increase Tesla's margins anywhere from 3-6% plus given US demand a massive boost from the consumer EV credit. The effects of the IRA on Tesla's earnings in Q1 will be a shocker to Wall St combined with Tesla's valuation being firmly in value stock territory, will lead to a strong recovery.
The longer term, things will ultimately come to a head when Tesla drops the price of the 3/Y from the luxury category to the mass consumer category thanks to continued cost reduction, 4680 in volume production, FSD being completely autonomous leading to very high adoption rate, possible Robotaxi, Tesla Energy becoming a large port of Tesla's revenue and earnings. This will be the further re-evaluation that coincides with consolidation across the industry in the form of many auto makers going belly up. I think this happens around 2025, possibly as late as 2026
I could also see a 3rd re-evaluation in between these two events where Tesla Energy revenue/earnings becomes a large enough portion of Tesla's overall revenue/earnings that it forces the issue. Maybe something like 20% of revenue/earnings.
