In working out a retirement plan, I've been calculating what future gains might be useful to base projections upon.
Quoting a piece, but responding to all. One thing I recommend is sort of a sensitivity analysis - what return do you need from TSLA (as long as you're calculating end results) to support retirement? If you need something like 10-20%, that might be modest compared to some periods of historical results, and might even be modest compared to what we/you expect between now and 2030 for TSLA.
If it's closer to 0% then you're more than ready and you've got a fair bit of buffer.
I used the Fidelity retirement planning calculator which bases its portfolio estimates in historical results. More exactly, it takes one's portfolio and backtests it using different starting years for the assumed length of retirement and provides a terminal value of the portfolio. You also have the ability to provide very detailed expense forecasts, such as a big lump in 5 years to buy a Roadster
So that's the future returns that I used, and in fact the most conservative, was what I used. Fully expecting to beat that handily with my overweight TSLA portfolio. But not NEEDING it to beat - it only needs to match the long run conservative (close to work case) return, that also encompasses a variety of particularly bad and good times.
If your retirement is highly sensitive to your returns, and especially if you need a steady and consistent 10% + return, then that sounds to me like retirement is premature. Even if 20% / year sounds like easy mode for TSLA, that's still an amazingly high historical return for long periods and you're going to kind of be in a bind if something significant about the TSLA investment hypothesis changes (Elon gets hit by a bus, an accounting scandal, a major and extended macro downturn, ...). You'll want some sort of fallback that is closer to the long run return (well - I think that anyway).
So I didn't forecast TSLA returns at all. I used the retirement calculator and made sure that the conservative result was still a good result. That means that the average and good results will be amazing. Since I expect TSLA to beat that conservative result like a drum, I'll have a lot of charitable donations to make!
It's possible I've been too conservative, but I've also gone from growth in order to afford retirement, to retiring, over the course of 2020. I think that I'll never have the regret that I kept working much longer than I should have.
