Martin Gilbert: What I Would Like To See From The Autumn Budget

Improving and expanding US infrastructure involves more than building roads and bridges. While efficient transport systems are vital, without things like reliable communications networks, safe water and a dependable power supply, the economy simply wouldn't be able to function. This constant need to improve the country's infrastructure means that many companies stand to benefit throughout the process.

The fact that demand for infrastructure is consistent means it is also largely uncorrelated to the ups and downs of the broader economy. That makes it a useful point of diversification for investors.
