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.
US equities were effectively unaffected
The S&P 500 closed slightly positive on July 7, 2005. Markets had internalized terrorism risk as episodic rather than systemic.
Markets learn to price recurring risk categories
Each successive attack — Bali (2002), Madrid (2004), London (2005) — produced a smaller market reaction.
Geopolitical shocks without economic transmission fade fast
The attacks did not disrupt supply chains, energy markets, or trade flows.
For your portfolio
By 2005 markets had learned to price terror attacks as episodic rather than systemic — US equities finished that day slightly higher. The respectful takeaway for a portfolio is preparation over reaction: if a tragedy of this kind would tempt you to sell, the allocation was likely too aggressive before the news.
