The Brexit vote stunned markets — polls had predicted Remain. The S&P 500 fell 5.3% over 2 trading days, then fully recovered within 2 weeks. The UK's FTSE 100 recovered within 3 days (weaker pound boosted exporter earnings).

What history says
Editorial commentary written by ALAN analysts. Figures cited below are analyst-authored context — they are not derived from the chart above and may reflect different windows or sources.
Full recovery in 2 weeks — one of the fastest geopolitical recoveries
The initial shock was about positioning (everyone was positioned for Remain). Once positions adjusted, the fundamental impact was recognized as minimal for US equities.
The actual economic impact took years to materialize
Brexit's real effects (trade friction, supply chains, immigration) unfolded over 5+ years. The market was correct to shrug off the vote itself — immediate GDP impact was near zero.
Lesson: political events rarely warrant portfolio changes
An investor who panicked out on June 24, 2016 missed a +20% rally over the subsequent 12 months. Political surprises create volatility, not permanent losses.
For your portfolio
Referendum-style binary events are hedging problems, not allocation problems. If a known-date event could force you to sell, size the position so it cannot — the two-week Brexit round trip punished anyone who converted a paper drawdown into a realized one.
