Twelve Rules for Riding a Bubble With Jeff deGraaf, Micron and Sandisk (Finally) Pull Back, Housing Stocks Crash

In this high-energy episode of The Compound and Friends, hosts Josh and Michael dive deep into the explosive rally in semiconductor and memory stocks, particularly focusing on the Korean market and companies like Micron and Sandisk. They welcome guest Jeff deGraaf of Renaissance Macro, who introduces his '12 Rules for Riding a Bubble,' emphasizing that a sector or index doubling in two years is a critical warning sign—what he calls a 'yellow flag'—not a sell signal, but a call to reduce position size and manage risk. DeGraaf draws parallels to historical bubbles like the South Sea Company and the 1990s tech boom, warning that even geniuses like Isaac Newton fell victim to market mania. The hosts then pivot to a nuanced discussion on whether the current surge in memory stocks is rational or speculative, with Michael arguing that the quadrupling of forward earnings for MSCI Korea makes the rally fundamentally justified, not irrational. They explore the broader 'AI industrial bubble' thesis, citing rising CapEx, declining returns on investment, and historical precedents like the fiber optic boom. The episode also highlights the collapse of housing-related stocks—Whirlpool, Zillow, Home Depot, and Lennar—painting a stark contrast between the tech boom and a deep housing market depression. Finally, the hosts analyze Goldman Sachs' technical setup and the mysterious price alignment between Netflix and Spotify, concluding with a call to stay alert to market signals and structural shifts. Key takeaways include: (1) A sector or index doubling in two years is a red flag for potential bubble behavior, not a reason to short, but to de-risk; (2) The current memory stock rally is driven by a fundamental earnings explosion, not just speculation; (3) The AI boom may be an 'industrial bubble' with high CapEx and uncertain returns, echoing past tech bubbles; (4) Housing stocks remain in a prolonged downturn, signaling broader economic imbalances; (5) Technical indicators like Goldmans’ 1,000 breakout level may serve as market mood rings for future momentum; (6) Investors should focus on de-risking sequences, not calling tops, to maximize terminal wealth; (7) The market is rewarding momentum and punishing misses more than ever, creating extreme asymmetry; (8) The era of 'asset-light' tech dominance may be ending, with hyperscalers now becoming capital-intensive industrial players.
