·1 hr 28 min·5 clips

Fidelity Magellan earned 18% to 20%, but many investors got zero or negative returns.

1. Mutiny Investing Podcast episode 50 centers on Dr. David Rhoiney talking about Twitter, investing, and surgery. 2. Dr. David Rhoiney is a surgeon and guest, and he uses Twitter, reading, and direct messages to speed-learn finance. 3. The episode asks what a doctor should study and own when index funds do not feel like enough. 4. Rhoiney says Twitter works like Google because he can ask finance questions and get feedback from real people. 5. He says a PhD in banking sent him papers in DMs while he was watching the SVB collapse. 6. He describes Twitter as a “live notebook” that shows what he is reading. 7. He contrasts that with online course sellers and says learning in public helped him build expertise. 8. The conversation turns to the idea of a “good manager” and why that standard is hard to define. 9. They discuss Fidelity Magellan, where strong long-term returns did not translate into positive investor outcomes. 10. The host calls the behavior a “babysitter tax,” linking it to avoiding bad investor decisions. 11. Rhoiney says he was put into a 60/40 portfolio at age 18 by a Primerica salesperson who was also his basketball coach. 12. He says reading The Intelligent Investor made him expect Warren Buffett-style results, but that did not match his experience. 13. He explains that his own path into investing has been “a lot of stumblings” and repeated rabbit holes. 14. He says he is 38, works as a surgeon, and wants to maximize the return on his earning years. 15. He names small businesses, real estate, private equity, and VC as areas he has examined for asymmetric returns. 16. He warns doctors against buying random strip malls or land they do not understand. 17. He says Market Wizards taught him that the main lesson is finding what fits you and what you can stick with. 18. He compares surgery to five years of layered observation, where trainees learn to see bleeding, structures, and instrument risk. 19. The tone is conversational and reflective, with the host asking follow-up questions about investing, sleep, and residency. 20. People interested in surgeon perspectives on markets and learning in public will like it; passive investing purists may skip it.
