SpaceX skepticism dominates alongside retirement withdrawal-rate research

This author is not making many trade calls; the window is mostly analytical, centered on SpaceX valuation skepticism and retirement withdrawal-rate research. The only public-equity tilt is bearish on TSLA as an inflated comp to an even more stretched SpaceX valuation, while mega-IPO history is used as a cautionary base-rate framework. No explicit position disclosures, adds, trims, or exits appear in the input.

Direction this week

The author’s investable concentration is bearish valuation framing around SpaceX and TSLA, supported by mega-IPO base-rate examples across BABA, SNAP, META, RIVN, V, and GM. Most activity is non-ticker retirement research around Bengen’s updated withdrawal-rate framework, with no disclosed adds, trims, exits, or explicit trade entries.

Grade is our human read-worthiness rating; trader score is a rolling 20-bet hit-rate/alpha composite — different things, often disagreeing. “Since then” is direction-unaware in the table; the summary line above adjusts for which way they leaned.
