Although the tragic loss of life in London is distressing, one lesson is that the financial markets can withstand such a shock. European stock markets all closed with losses of less than 2% on July 7, and U.S. stocks rose. It may be that the world has now become so accustomed to random violence on a mass scale that, after an initial knee-jerk reaction, markets go back to what passes for normal.
That wasn't always the case. On the first trading day after Pearl Harbor, the S&P 500 fell 4.4%. It took 18 trading days for the market to bottom at 10.8% below its close before the attack. Recovery to the pre-attack level would be 257 trading days from the initial shock.
Sam Stovall, Standard & Poor's chief investment strategist, looked at the market's reaction to a half-dozen shocks over the past 65 years: Pearl Harbor, the Cuban missile crisis, President Kennedy's assassination, Iraq's invasion of Kuwait, September 11, and last year's bombings in Madrid. Stovall found that the average one-day decline was 2.9%. The bottom was 6.3% below the closing price prior to the shock, and it was reached in six trading days. Full recovery arrived, on average, in 55 trading days.
The quick market rebound in the wake of the London bombings reinforces our opinion that stocks will strengthen in the second half of 2005. At least some investors appear to have learned the lesson of perseverance. But it's a shame that the cost of that lesson was so high.
