3 Top Buffett Stocks to Buy and Hold for the Long Haul

Berkshire Hathaway has pivoted into tech over the past decade and now holds material positions in companies that remain compelling on fundamentals and growth. The article highlights three Berkshire-owned stocks: T-Mobile (TMUS) — now paying a dividend started Dec 2023 and recently raised 35% to $3.52 annually (yield ~1.7%), up >45% in the past year, P/E ~25; Nu Holdings (NU) — Brazil-led fintech with 105 million customers as of Q2 2024 (customer base +21m YoY, ~56% of adult Brazilians use Nu), stock up ~120% last year, P/E ~47; and Amazon (AMZN) — ~$2tn market cap, AWS drives the majority of operating income, stock up ~50% over the last year (over 140% since Berkshire’s 2019 entry), P/E ~46. These metrics frame the pieces as buy cases based on growth, valuation comparisons and AI/cloud tailwinds for AWS.

Analysis

Market structure: Winners are AMZN (AWS-driven profit growth), TMUS (spectrum/5G share gains) and NU (rapid customer adds in underbanked LATAM); losers are legacy telcos (T, VZ) and incumbents in LATAM consumer banking. Market-share dynamics favor scale and platform providers — AWS and Tencent-like regional fintechs — enabling pricing power in cloud and digital payments while compressing margins for low-growth carriers. Recent moves: AMZN +50% Y/Y (P/E ~46), NU +~120% Y/Y (P/E ~47), TMUS +45% Y/Y (P/E ~25) imply growth expectations priced into multiples.

Risk assessment: Tail risks include a Brazil macro shock or BRL devaluation (>10%/yr) that would spike NU credit costs, US/EC antitrust action targeting AMZN AWS or marketplace rules, and telecom integration/CapEx overruns at TMUS post-Sprint. Near-term (days–weeks) catalysts: CPI, Fed guidance, company earnings; medium-term (3–12 months): Brazil elections, AWS AI contract renewals; long-term (3–5 years): AI-driven cloud share shifts and fintech unit economics normalization. Hidden dependencies: NU’s growth depends on cheap funding and FX stability; AWS depends on sustained enterprise AI spend and capex cadence.

Trade implications: Direct: initiate a 2–3% portfolio long in AMZN as a core 12–36 month hold to capture AWS/AI tailwinds, with a 20% trailing stop; add 1.5% long TMUS for 6–18 months targeting additional share gains, stop 18% on material ARPU erosion. Pair trade: long TMUS (1.5%) / short VZ (1.5%) to express wireless share-shift; expect alpha if TMUS outgrows by >200 bps share in next 12 months. Options: buy 9–12 month AMZN call spreads (e.g., buy 1 5% ITM, sell 1 30% OTM) to cap premium with 30–50% upside target; hedge NU exposure with 6–12 month BRL puts or buy-credit-default hedges if BRL falls >10%.

Contrarian angles: Consensus underestimates regulatory and FX drawdowns — NU’s P/E 47 assumes benign macro; a 300–500 bps rise in NPLs would reprice earnings 30–40%. Amazon’s scale masks potential margin cyclicality if 2026 enterprise AI capex stalls; monitor AWS gross margin movement quarterly (>200 bps decline is a sell signal). The market may be underpricing downside at T/VZ — these remain attractive tactical shorts if TMUS ARPU converges toward parity and churn improves. Historical parallel: post-consolidation telecom cycles show multi-year margin recovery delays; position sizes should be convex to downside triggers.

Key Decisions for Investors

• Establish a 2–3% long position in AMZN as a core holding with a 12–36 month horizon to capture AWS/AI growth; use a 20% trailing stop and scale into weakness >5% pullbacks.
• Allocate 1.5% long to TMUS for 6–18 months to play spectrum-driven share gains; pair with a 1.5% short in VZ to isolate share-shift risk; exit if TMUS ARPU falls >5% sequentially or VZ reports improving net adds for two consecutive quarters.
• Initiate a 1% speculative long in NU but hedge FX and country risk: buy 6–12 month BRL puts sufficient to cover 50% of position value if BRL drops >10% or set a stop-loss if NPL ratio rises by 300 bps quarter-over-quarter.
• Use options to limit capital: buy 9–12 month AMZN bull call spreads (approx. 5% ITM buy / 30% OTM sell) sizing premium to no more than 1% of portfolio and target 30–50% return; avoid uncovered calls given potential volatility.
• Reduce exposure to legacy telco equities (T, VZ) by 50% vs benchmark weight over the next 3 months and redeploy proceeds to AMZN/TMUS and defensive cash; consider shorting VZ on rallies above 5% with a 12-month horizon if competitive losses persist.
