In one sentence: After a reminder that spreading money across everything is not investing, Phil and Danielle show where to find what great investors are buying (13F filings and the sites that compile them), why big funds must buy slowly, and why the 48-hour 5% filings matter, saving the "how to use it" for next time.
Key ideas
- What your advisor tells you. Diversify across hundreds of stocks via funds and you will "probably do okay" in the long run, but the long run can be about 25 years to break even: money put in late 1928 got back to even in 1955, and money put in in 1965 in 1983. Phil gives these dates from memory. [00:00–03:00]
- Index funds are for people who already have money. Phil says Buffett's index advice is for his heirs, who already have lots of money, and that the financial-services industry is built for people with enough assets to be worth managing. Phil's view: if you don't want to learn to invest, the index is "the only real game in town". [02:00–06:00]
- Abdicating and speculating. Phil says putting money across 500 things you don't understand is abdicating the investment process and speculating that they'll go up, since you can't know what they are worth. [07:00–09:00]
- A late-2017 warning. The market is in its ninth or tenth year of a rising run, taxi drivers have tips, and everyone is excited about Bitcoin. Phil says this is the point where prices drift away from cash flow, and patience and humility matter. He cannot say when it ends. [09:00–13:00]
- Look over the shoulders of the best. Danielle tried this herself on EDGAR. The SEC site is hard to use and the raw Berkshire 13F doesn't show whether positions are new, added or sold. You need the timeline. [13:00–19:00]
- 13F filings. Large managers report holdings quarterly (up to about 45 days after quarter end), so the information is delayed. [17:00–23:00]
- Why big investors must buy quietly. A fund buying huge amounts can't do it in a day without spiking the volume (the cantaloupe example). Phil's Apple example: 42 million shares bought in 400-share pieces over months, so the filing may show a position that took four months to build. [19:00–24:00]
- Where to look. Phil names his own site's curated list of 46 gurus, Dataroma (free, about 75–80 managers), GuruFocus (about $300 a year), HoldingsChannel and WhaleWisdom. His advice is to check two or three of them against each other. [23:00–27:00]
- Know who you're watching. A fund that owns a bit of everything tells you little. You want managers who invest the way Rule #1 does. [24:00–25:30]
- The 48-hour filing. Anyone who owns more than 5% of a company must report buying or selling within 48 hours, and that's the faster signal. Phil says if a big holder starts selling, you want to know. [27:00–28:30]
- The edge is real but not a shortcut. Phil recalls a study in which buying Buffett's disclosed picks on the last day of the month at the worst price still compounded at around 20% for 30 years (his memory, no source given). Then he and Danielle agree the next step is to ask whether you understand the business, rather than just copy. [28:00–29:30]
How it maps to RuleOne
- This is the cloning input to the planned Radar agent: 13F buys by the managers you admire, and 13D/13G filings for the faster 5% signal. The screen's event watch already flags 13D-type filings.
- The stock pages link out to SEC EDGAR for the original filings, but as Phil and Danielle find, the timeline is the useful part and a compiled view does that better.
Buffett, Munger and Graham links
- Buffett's 1984 talk "The Superinvestors of Graham-and-Doddsville" is the classic case for following a school of investors who reach similar results from one idea.
- Buffett on size as an anchor (letters of the 1990s and 2010s) matches the point about big funds having to buy slowly.
- Index-fund advice: Buffett's 2013 letter, which describes his instructions for his estate.
Words to know
- 13F: quarterly report of holdings by large managers.
- 13D / 5% rule: a filing within days when an owner crosses 5% of a company, with later changes reported quickly.
- Volume: the number of shares traded in a day.
- Guru: the hosts' word for an investor whose method you respect.
Try this
Open a free compiled source of 13F data. Choose one manager whose method you understand, and list their five biggest positions and one that changed since the previous quarter. On All stocks, see if any of those names are on the screen, then note one you'd have to research first.
Check yourself
- Why can't a big fund buy a position in a day?
Answer
The volume spike would show the market someone is buying, and the price would rise, so they buy in small pieces over months. - Why is the raw EDGAR 13F hard to use?
Answer
It lists holdings but not the timeline: whether a stock is new, added or sold since the last filing. - What is the faster signal than a 13F?
Answer
The filing required within 48 hours when someone holding more than 5% of a company buys or sells.
