Ditto with what the others had contributed. Going in 100% is literally multiplying concentration risk on so many levels. (Market risk, industry risk, sector risk, asset risk, single stock risk). Unless you are fully convinced with the stock, don't go in with the herd mentality just by ' hearing ' that it has great potential. I will play the devil's advocate. I have been vested in Tesla since mid-2019 when the price was around 200~ pre-split. I read news related to it at least once every other day, by keeping up with non-mainstream finance media. Whatever I say below is solely my opinion, and should not be treated as investment advice. There is a stark disconnect between Wall St. and the fundamentals of Tesla . Most, at the very least, 90% of analysts are still viewing Tesla as an automotive company. Traditional Wall St. Equity Research division operates in sectors/industries. I view Tesla as a company that is infiltrating all kinds of industries. Automotive, software, energy (renewables, Solar, Battery), ride-hailing, infotainment, etc. It is hard for traditional analysts to understand Tesla as these sectors are inherently intertwined within Tesla's business model. I see a paradigm shift from traditional ICEV to BEV. During the pandemic, Tesla manages to hit record deliveries, quarter over quarter. Mind you, it was during a pandemic where they had their factory shut down for 7-8 weeks! While Tesla was seeing growth in their deliveries, other traditional ICE manufacturers saw their deliveries and demand plummet. Credited engineers, including Sandy Monroe, had alluded to Tesla being years ahead of their competitors in terms of technology. If you went through their recent battery day presentation, what they are essentially telling us is their planned roadmap to scale up battery production, increasing range and efficiency, and reducing the cost of battery production. These are all plans that Tesla is doing to grow. I am not a material scientist nor engineer. I literally went to read up Battery research papers and listen to engineers rambling away with technical jargon that took me hours to understand. The result was truly impressive, what Battery Day was about. Just a final point before I bore you. What I liked about Tesla is, they barely spend a single dime on marketing. Go YouTube and lookup for Tesla. YouTube personalities, influencers, celebrities are raving over their new Tesla vehicles. Easily a few hundred thousand ~ million views per video. People who bought Tesla will talk to their family and friends about Tesla. Through word of mouth, demand will increase exponentially. That is the power of Tesla. The more Tesla cars Tesla sells, the more Tesla car Tesla sells. I still have a library of bull theses (ride-hailing network, Robo-taxi TAM, solar power TAM, battery patents, etc.) that I had formed throughout my one year plus of coverage. It is now up to you to do your own due diligence, form that conviction, and invest in it. Coming back to your earlier point. No, do not all in Tesla. Unless you have other streams of income that will still keep you living comfortably if Tesla goes to zero. Will be more than happy to talk about Tesla if you like to.
