December 2025 Random Ramblings
Summary
Andrew Walker’s working 10-year thesis is that public markets will keep getting “weirder and weirder” as computers eliminate much of the simple fundamental alpha. Like basketball optimizing toward rim shots and threes, or computer chess becoming unrecognizable to ordinary players, market strategies are migrating to their extremes. Zero-day trading, leveraged ETFs, retail participation, and prediction markets favor unusual, path-dependent situations over stocks that merely screen as cheap.
Fundamental analysis remains “table stakes,” but Walker expects more edge in situations where attention and reflexivity can change the company itself. His example is Opendoor: a retail “mob army” helps drive the stock up 20x, enabling equity issuance and potentially reshaping the company. He explicitly says he is not calling that a pump-and-dump; he sees it as evidence that “all the juice” may increasingly be in unusual situations.
Walker has become skeptical of valuation theses that a Yahoo Finance screen can reproduce in five seconds. An 8x earnings multiple or low price-to-book ratio may look attractive, but he increasingly suspects such simplicity offers “not only no alpha there but probably negative alpha.” He concedes that a diversified basket of 50 low-P/E stocks might eke out a return, but doubts it produces large alpha.
Buybacks and hidden real estate have become much smaller parts of Walker’s approach because both can sit atop deteriorating businesses. Bed Bath & Beyond bought stock around $40 before later diluting shares around $0.10 in a death spiral, while department stores such as Macy’s, Kohl’s, Nordstrom, and Seritage produced poor long-term outcomes despite property theses. His diagnosis: “You have all this real estate ownership attached to a truly negative-EV department store business.”
Three years without performance has become Walker’s practical timeout for forcing a thesis review. Cable taught him that a monopoly-or-duopoly premise could not simply survive the arrival of fixed wireless and the possibility that many markets had become oligopolies: “The market is hitting you in the face with the fact that the thesis is wrong.” A flat or falling stock does not automatically require selling, but his own history says he usually would have been better off moving on.
Risk management now means refusing to turn a broken event trade into progressively deeper flavors of value investing. His recurring loss pattern starts with a takeover trade at $10, continues after the deal dies at $9, and gets relabeled as value at $6 and distressed at $3. The corrective is blunt: “The answer there is you’ve got to sell.”
Exceptional track records may reflect insight, luck, or an investor’s willingness to ignore a risk that happened not to materialize. Walker has interviewed investors whose largest position rose 6x in 18 months, yet wonders whether they identified and correctly dismissed the risk or simply “glossed over” it. His podcast has also made him more alert to domain arrogance: smart media investors can misunderstand tender-offer mechanics just as smart commentators misunderstood specific performance during Elon Musk’s Twitter bid.
Deep dive
1. Simple alpha is disappearing into stranger markets
Walker’s working thesis after about 10 years of professional public-market investing is that markets are entering “the final stages of the efficient market” and getting “weirder and weirder.” SPACs and the post-COVID boom were early signs; zero-day trading, leveraged ETFs, retail participation, and prediction markets are now blending speculation, attention, and investing.
His basketball analogy supplies the mechanism. Once mathematics established that efficient offense meant shots at the rim, free throws, or three-pointers, the middle disappeared; elite basketball became unlike the game ordinary people play. He sees a similar transformation in high-level computer chess, which began looking like “a completely different sport.”
Markets should follow the same path: computers have made straightforward fundamental analysis largely table stakes. Some of the year’s individual-stock leaders may still have long-term paths “to zero,” but can rise 10x first; path dependency matters when a higher price itself creates financing and strategic options.
Opendoor is Walker’s specimen of reflexivity at the frontier. Build a following early, create a cult around the stock, drive attention and a 20x move, then issue equity and potentially reshape the company. He explicitly says he is not calling this a pump-and-dump. He thinks adaptable investors will increasingly find alpha where “all the juice” sits: unusual situations beyond conventional fundamental value.
2. Cheap multiples, buybacks, and hidden property have become less reliable standalone theses
Walker’s first major change of mind is about pure valuation. He still feels the pull of 8x earnings and price-to-book, but warns: “If your core thesis is something that can be recreated by a Yahoo Finance screener in five seconds, you’re probably not going to get paid for that.”
He has also downgraded buybacks from a huge buy signal to one useful input. The John Malone-style combination of leverage, free cash flow, and aggressive repurchases often belonged to legacy businesses with no reinvestment runway; technology then attacked their moats, with Netflix and cable networks as his headline example.
Bed Bath & Beyond captures the capital-allocation danger: management repurchased stock around $40, then later issued shares around $0.10 in a death spiral. Walker still prefers buybacks to dividends when executed intelligently—and enjoys tracking daily UK repurchase disclosures—but no longer treats a shrinking share count as evidence that the underlying business is safe.
Hidden real estate produced the same disillusionment. Seritage offered a spin-off, rights offering, and property story that looked extraordinary to value investors, while Macy’s owned Herald Square; yet department stores broadly became 10-year disasters. The businesses consumed value every year even as investors focused on the land: valuable real estate attached to “a truly negative-EV department store business.”
3. Timeouts and fast exits matter more than defending the original price
Walker has moved from “zero out of 10” to roughly one out of 10 on technical analysis. He still regards much of it as “mumbo jumbo” or “voodoo,” but now sees possible risk-management value in watching a 200-day moving average on shorts or relative-strength indicators when deciding whether to deploy cash into an oversold index.
His larger evolution is abandoning indefinite patience as a virtue. Three years without progress does not prove the market is right, but it is long enough to ask, “Is it me or is it them?” His experience says a position bought at $50 in 2019 and still at $50 in 2022 was usually better sold and perhaps revisited after new evidence emerged.
Cable is the painful example. Walker’s 2016 thesis worked for five to seven years because many markets looked like monopolies or duopolies; the subsequent three years were terrible and should have forced recognition that fixed wireless had created the possibility of oligopolistic competition in many places. Better investors saw the threat sooner while he kept emphasizing cash flow and asset value.
The same discipline applies faster after material news. His instinct is to love at $8 what he liked at $10, but maturity means reassessing rather than defending ownership. The nightmare progression—“this was an event, now it’s a value investment,” then deep value, then distressed—begins when a failed takeover trade is not sold after its catalyst dies.
4. A grand-slam record does not reveal how much was skill
After roughly 350 podcast episodes, Walker says even a guest on the left tail can teach him something: an hour spent probing another investor’s analytical holes makes similar weaknesses easier to spot in his own portfolio. He cares less about charisma than whether the fundamental work is there. He hopes—and acknowledges he may be talking his book—that the average guest is a very above-average investor.
The deeper puzzle is that the best track records do not always belong to the most impressive thinkers he has interviewed. Two equally smart venture investors can become a legend and merely average respectively because only one entered Facebook in 2009; in public markets, one grand slam can likewise separate a very good record from an unbelievable one.
When a guest’s largest position rises 6x in 18 months, Walker asks a counterfactual question: across 10 other universes, is that investor “dunzo” in eight? A 10x may mean the investor identified and correctly dismissed a risk—or that arrogance allowed them to gloss over a risk whose benign resolution made the record look brilliant. He does not know which explanation is right.
5. Expertise travels badly across domains, while investing rewards humility
Walker sees the same uncertainty in commentary on the Paramount–Netflix bidding war for Warner Bros., where he disclosed that he is very long Warner Bros. Smart media investors and commentators can sound “comical” when discussing tender-offer mechanics. During Elon Musk’s Twitter bid, Walker likewise heard smart people make legal claims he considered obviously wrong; he recalls a Delaware judge saying Musk could get out of the deal for $1 billion and says he wondered whether the judge understood specific performance.
His unresolved question is whether those mistakes are isolated “shoe-button expert” overreach or evidence of shortcomings in the person’s home field. He does not claim an answer; the point is to remain suspicious when prestige in one domain gets mistaken for mastery in another.
Walker closes by hoping today’s thinking will look foolish to his future self. Investing’s appeal is that practitioners probably do not peak until their mid-to-late 40s, giving him another decade to compound judgment even as physical performance fades: “I’m so much better today than I was 10 years ago,” and he wants that sentence to remain true 10 years from now.
