Ordinary investors could be forgiven for scratching their heads at the market reaction to a war few expected.

Yes, stocks have been volatile, but Europe's Stoxx 600 was ultimately flat in the week following Russia's February 24th invasion of Ukraine, while the S&P 500 enjoyed strong gains.

You can argue stocks were already oversold following earlier steep losses. You can argue modest European valuations might protect European stocks, as Goldman Sachs did last week. You can argue the damage to the global economy will be contained.
