Record high American shares can grow even higher, Bloomberg reports with reference to Nobel laureate Robert Shiller known for his analysis of assets price bubbles.

According to expert opinion, stock market can grow much higher before it starts to fall. But the degree of risk is quite high.

This opinion differs from view of strategists from Goldman Sachs and JPMorgan Chase that recently warned about dangerous influence of trade war between China and the US.

Shiller instead focuses of the strategy of US President that is aimed at stimulating American corporations and will support the market.

Index S&P 500 gained almost 9% this year already.
