Jonathan Wellum: What To Do During a 10–20% Market Drop

Overview

This summary outlines a four‑part framework advisors and investors can follow during a 10–25% market drawdown. It focuses on emotional discipline, valuation, capital allocation, and patient buy‑and‑hold discipline, with concrete timelines, examples, and an actionable checklist.

Key framework — 4 actions during a 10–25% drawdown

1. Emotional discipline / temperament

• Control panic and avoid selling from fear. Temperament is a primary investing edge (paraphrase of Warren Buffett).
• Behavioral note: drawdown anxiety often feels about twice as strong as the joy from gains.
• Advisor actions: proactively reassure clients, explain the investment rationale, and take calls to calm panicked clients.

“Temperament is a primary investing edge.” — paraphrase attributed to Warren Buffett

2. Valuation focus

• Re‑check fundamentals and valuations rather than reacting purely to price moves.
• Core thesis: volatility ≠ risk. Risk is the probability of permanent loss of business value. If the business is unchanged but the price falls, the investment can become more attractive.
• Example: a hypothetical Exxon price falling from $200 to $100 could represent a better entry if the long‑term prognosis is unchanged.
• Suggested holding horizons: 3–5 years. Buffett’s test: buy only if you can tolerate the stock market being closed for 5–10 years.

3. Allocation of capital

• Maintain appropriate asset allocation (equities, fixed income, cash) so short‑term needs don’t force selling into weakness.
• Keep extra cash when markets are rich/expensive so you can opportunistically buy favorites on dips and lower your book value.
• Advisor action: ensure portfolios have room to be opportunistic without jeopardizing long‑term goals.

4. “Lethargy” (buy‑and‑hold discipline)

• Favor a patient, low‑turnover approach (Charlie Munger’s “lethargy bordering on sloth”) to preserve compounding.
• Frequent trading can dramatically reduce investor returns — example: Peter Lynch compounded Fidelity’s Magellan Fund at ~25%/yr (1977–1990), while retail investors in the same fund averaged <7%/yr due to poor timing and high turnover; some retail investors had negative returns.
• Tax caution: selling in taxable (non‑registered) accounts can crystallize gains and truncate compounding.

Concrete numbers, timelines, and performance metrics

• Typical drawdown range discussed: 10–15% (core), with examples up to 20–25% and 30%.
• Example price move: hypothetical Exxon from $200 down to $100.
• Holding horizons recommended: 3–5 years; Buffett’s 5–10 year tolerance test referenced.
• Historical performance example: Peter Lynch’s Magellan Fund ≈25%/yr for 13 years (1977–1990); retail investors in the fund averaged <7%/yr because of trading/timing behavior.

Assets, instruments, and funds mentioned

• Equities / stocks (general)
• Fixed income (bonds)
• Cash
• Exxon (used as a price example)
• Fidelity Magellan Fund (Peter Lynch)
• Berkshire Hathaway (context for Buffett/Munger references)

Methodology / Step‑by‑step checklist for advisors and investors

1. Pause and manage emotions; avoid reacting to shock headlines.
2. Reassess each holding’s fundamentals and valuation — buy only if business prospects remain intact.
3. Verify portfolio asset allocation and confirm cash reserves for short‑term needs and opportunistic buying.
4. If valuations permit, deploy cash to buy high‑quality companies at lower prices to reduce book value.
5. Favor low turnover for high‑quality holdings to let compounding work.
6. Consider tax consequences before selling in taxable (non‑registered) accounts.
7. Advisors should proactively communicate and counsel clients through the volatility.

Explicit recommendations and cautions

• Don’t equate volatility with permanent risk; view price drops as potential buying opportunities when fundamentals are unchanged.
• Maintain cash buffers so you aren’t forced to sell into weakness.
• Avoid market timing and high turnover; historical evidence shows this reduces investor returns.
• Be mindful of tax implications in non‑registered accounts when selling.
• Advisors should emphasize temperament and valuation discipline and provide reassurance during panics.
