  • "We do not think that [the market] can go up every day, but we do think it can go up more, ... because positioning is still relatively low," top J.P. Morgan strategist Marko Kolanovic says.

  • "If this [U.S.-China] trade deal for some reason is falling apart, we would probably have to change our view entirely," he says.

The market has been rising since it hit "rock bottom" in December and there's enough momentum in the United States economy alone to carry the cycle as global growth slows, top J.P. Morgan strategist Marko Kolanovic told CNBC on Wednesday.

Kolanovic, whose calls have moved the stock market in the past, credited shifting policy in the Federal Reserve, progressing trade negotiations between the U.S. and China, and declining volatility for investors' willingness to put more money to work. Investors are more comfortable taking on more risk when the market is not up and down as much as 10 percent on a regular basis, the bank's global head of quantitative and derivatives strategy said.
