Warren Buffett's Successor, Greg Abel, Now Has $46 Billion of Berkshire Hathaway's Capital Devoted to His Top Investment Idea

Greg Abel succeeded Warren Buffett as Berkshire Hathaway CEO on Dec. 31 and now oversees a $316 billion investment portfolio; Abel has allocated roughly $46 billion (about 15% of invested assets) to Japanese companies. Holdings as of April 5, 2026: Mitsubishi $13.27B, Mitsui $11.69B, Itochu $8.62B, Marubeni $5.74B, Sumitomo $4.23B, plus a Tokio Marine stake (initial $1.8B, now ~ $2.2B). Berkshire has authorized $78B in buybacks since July 2018; the article highlights Japanese firms' shareholder-friendly capital returns, modest executive pay, and lower P/E multiples versus an expensive U.S. market as the rationale for the allocation.

Analysis

Berkshire’s outsized redeployment into a single foreign market creates a new, concentrated vector of idiosyncratic risk that is not reflected in headline holdings figures: implicit currency exposure, regulatory/tax sensitivity and correlation to that market’s valuation cycle now matter meaningfully for the parent stock. Because the allocation is large relative to historic norms, marginal moves in that market (or in its central bank policy) will transmit to Berkshire’s EPS multiple more quickly than before, giving short-term catalysts (quarterly results, repurchase cadence) outsized impact on share-price volatility.

A less-obvious winner from this strategy is the ecosystem that services large cross-border equity stakes — investment banks, custody providers and indexes that track foreign large-caps — which stand to gain recurring fee and trading flow; conversely, domestic U.S. value managers could face renewed competition for capital as the narrative shifts toward allocating to attractively priced foreign cash-generative businesses. The management behavior this fund prefers (low pay, high capital returns) is fungible: if other large allocators follow, expect higher buyback activity and narrower free floats in that market, increasing idiosyncratic liquidity risk and event-driven dispersion.

Key risks that can reverse the trade are macro/currency shocks, abrupt shifts in local corporate governance/tax rules, or an underwriting shock in the insurance arm that forces liquidations; these are multi-month to multi-year risks, not intraday. Watch three near-term catalysts: (1) upcoming quarterly repurchase disclosures, (2) any central bank communication that tightens policy there, and (3) material M&A or activist activity — any of which can reprice both the underlying holdings and Berkshire’s multiple within 1–6 months.

Key Decisions for Investors

• Long BRKB (2% portfolio weight) — 9–18 month horizon. Size initial entry size 2% at market, add on a 10–15% pullback. Target +20% total return; hard stop-loss at -12% (or hedge with 1:1 6–12 month puts). Rationale: asymmetry from buyback-driven EPS uplift and re-rating if flows continue.
• Pair trade: Long BRKB / Short NVDA (equal-dollar) — 3–12 month horizon. This is a macro-rotation trade: isolate exposure to capital-allocation-driven rerating vs secular growth. Take profits if BRKB outperforms NVDA by 15% or cut if NVDA rallies >25% (buy protective calls on the short leg).
• Buy BRKB 12–18 month call spreads (debit-limited) — conservative convexity play. Example: buy longer-dated near-ATM calls and sell 25–35% OTM calls to finance; max loss = premium paid, target 2–3x on premium if repurchases accelerate and underlying rerates.
• Short NFLX via 3–9 month put spreads (small position) and allocate proceeds to the BRKB long — tactical hedge against a growth-to-value rotation. Trade size 0.5–1% portfolio; cut if NFLX underperforms growth peers by >12% or if subscriber metrics surprise materially.
