Wall Street sets record for longest bull run in history

Key S&P 500 index passes landmark as it goes 3,453 days without major correction

US stock markets passed another landmark on Wednesday as the S&P 500 recorded its longest rally ever, capping a near decade-long Wall Street boom that has gathered pace over the course of this year.

The S&P 500 share index, tracking the 500 biggest public companies in America, closed trading on Wednesday having gone 3,453 days - nearly nine and a half years - without a fall of 20% or more, which is the measure used by some analysts for handing it the status as the longest bull market in US history.
