"While there is concern, and it has become in vogue to say that stocks are expensive, it is hard to say what they're expensive relative to," Liam Dalton, president of Axiom Capital Management in New York, told Reuters. "Cash remains abundant and interest rates are low, and we should generally go up in an environment like that."
Gains in shares of Visa, Intel and American Express led the gains in the Dow, up 0.6 per cent, 0.6 per cent and 0.5 per cent respectively.
