Shrubbery Capital: What 15 Years In Hedge Funds Teaches You

Episode Summary

Executive Summary: This episode is a wide-ranging conversation with Shrub of Shrubbery Capital about his path from engineering and M&A into event-driven hedge funds, family office investing, and Twitter-driven idea generation. He emphasizes downside protection, trade structuring, timelines, technicals, and staying in the game, while sharing thesis examples in energy, uranium, tin, and recycling.

Main Topics: Career path and investing formation: Shrub recounts growing up in Cyprus, reading Peter Lynch and Soros, surviving early bubble experiences, studying engineering/economics/management, and moving from M&A into merger arbitrage and later hedge funds/family office work. Merger arbitrage and event-driven investing: He explains merger arbitrage as a core hedge fund discipline focused on spread capture, downside control, and non-correlated returns, and describes how event-driven funds use other angles like spin-offs, shorts, and deal structure. Risk management, leverage, and staying in the game: A major theme is capital preservation: stop-losses, respecting downside, avoiding overleverage, and learning through painful blowups. He argues that learning to survive matters more than any single winner. Technical analysis integrated with fundamentals: Shrub argues technicals are practical, especially for liquid names and retail investors, and should complement fundamentals rather than be dismissed. He stresses stop-losses, 200-day moving averages, and chart behavior. Thematic investing in energy, uranium, tin, and ESG distortions: He outlines a barbell portfolio that includes cheap cyclical/resource names and a few big thematic bets. He is bullish on energy, nuclear/uranium, and tin due to supply deficits, ESG-driven flows, and energy transition demand. Recycling and digital watermarking as a long-duration thesis: Shrub explains his fascination with recycling as a real-world ESG theme, highlighting plastic sorting economics, PureCycle, Digimarc, and Tomra. He sees digital watermarks as potentially transformative for plastics recovery and retail scanning. Portfolio philosophy and idea sizing: He prefers concentrated but diversified sizing: a mix of cheap stocks, thematic positions, and one or two high-upside 'lottery ticket' ideas. He avoids commitment bias and prefers public discussion without needing to defend a position indefinitely.

Key Arguments: Hedge fund experience is valuable because it teaches process, downside control, and how to structure trades around catalysts and timelines. The best trades are often not about being right on a business, but about getting the risk/reward, timing, and instrument structure right. Technical analysis can improve outcomes when combined with fundamentals, especially for traders without the ability to wait indefinitely. Retail investors should respect stop-losses and moving averages because large funds often sell mechanically or belatedly after technical breaks. Family offices are often more conservative and less educational for trading skill development than hedge funds or prop shops. ESG has changed market structure by forcing capital away from some sectors and toward others, creating both distortions and opportunities. Recycling is a credible long-term theme because plastic waste is under-recycled and improved sorting/watermarking could materially increase asset values. Energy transition creates multi-year demand for oil, nuclear/uranium, copper, nickel, and tin, while supply constraints and underinvestment may support prices. Investors should stay in the game, avoid oversized losses, and accept that only a few positions should be capable of changing life outcomes.

Data Points: Merger arbitrage fund AUM growth: less than $1 billion to $40 billion - Shrub described his first hedge fund growing massively over his five years there. Short subprime hedge cost: 1%-2% per year - The founder used subprime protection as an annual hedge before the 2008 crisis. Performance in 2008: triple digit returns - He said the fund made a fortune when the subprime/credit bubble burst. Twitter convertible strike: $52 strike - Shrub’s Twitter 2024 convertible example used to show downside protection. Twitter convertible entry price: 117 - He bought the convertible at 117 and described limited downside even as the stock fell. Twitter stock price: 44 - He referenced Twitter trading down sharply while the convertible held up better. Wirecard put payoff: 10x to 20x - He said the June puts went up about 20x and September puts about 10x after the fraud was revealed. Portfolio risk used on Wirecard: less than 50 bps - He sized the trade very small, but it still moved the portfolio positive for the year. Plug Power move: 2 to 18, then to 70 - He described buying Plug early, selling at 18, and missing the later surge. Needle on technicals: 50-day moving average held for nearly a year - He said Plug respected the 50 DMA from spring 2020 until early 2021. Uranium production: 125 million pounds per year - He cited annual uranium supply as part of the bull case. Uranium consumption: 180 million pounds per year - He said demand exceeds production by a wide margin. Uranium secondary supply: 25 million pounds - He included secondary supply in the uranium supply-demand calculation. Uranium deficit: 30 million pounds per year - He argued the market has a persistent annual deficit. Sprott uranium buying: 40 million pounds - He said Sprott has bought about a third of annual production. Tin stock valuations: about 2-3x EBITDA - He highlighted low valuations for listed tin producers like Alphamin and Metals X. Uranium valuation: about 20-30x EBITDA - He contrasted uranium equities with tin on a valuation basis. Plastic recycling rate: 14% - He said only 14% of plastic is recycled, motivating the recycling thesis. Steel recycling rate: 70%-90% - He contrasted steel recycling with plastic as an easier, more mature market. Paper recycling rate: 50%-60% - He cited paper as another relatively mature recycling stream. Mixed plastic value: ~200 euros/ton - He said dirty mixed plastic currently trades at low value. Clean plastic value: ~1,000 to 1,500 euros/ton - He argued better sorting/watermarks could dramatically increase recovered plastic value. PureCycle warrants: $2.50 to $18 - He described a large gain on warrants after the SPAC/vote process. Digimarc business revenue: $10 million to $15 million per year - He said the company earns this from digital watermarking on banknotes. Family office portfolio style: one or two high-upside names plus cheap value and themes - He described his barbell approach.

Pivotal Quotes: "Take care of the downside, and the upside will take care of itself." — Shrub: He presented this as a core lesson from his first hedge fund. "I don't really let something go down more than, say, whatever, 20% or 10% if it's a bigger position." — Shrub: He explained his personal risk discipline and stop-loss mindset. "I don't like to piss against the wind." — Shrub: He used this to explain why he embraces ESG-driven market flows rather than fighting them.

Implications: Listeners should take away a process-first investing framework: size small, respect timing and technicals, and use catalysts. The episode also shows how ESG and energy transition create real mispricings in recyclables, uranium, and industrial metals.
