Key quotes from the Reuters Investment Summit

NEW YORK (Reuters) - Strategists from top Wall Street Investment firms visited Reuters U.S. headquarters on Wednesday at the Reuters Investment Outlook Summit and discussed upcoming trends and risks for global markets.

The following are some of their key comments.

TOBIAS LEVKOVICH, CITIGROUP'S CHIEF U.S. EQUITY STRATEGIST:

"Semiconductor orders surging ... is not a good thing. This is not about demand; it is about supply. Chips are commodities; the only thing that matters is supply."

"The bottom line is what you want to watch is herd mentality. There's nothing wrong with investing in emerging markets. You just shouldn't do it all in one day."

ABBY JOSEPH COHEN, GOLDMAN SACHS' CHIEF U.S. INVESTMENT STRATEGIST:

"People are very, very sensitized to the fact that they are making investment decisions more quickly then they ever did before. Whether that is a good thing or a bad thing, we'll find out later on. Many people are so nervous about being burned that when they see anything going down, there's a tendency to bail out."

"This is a Federal Reserve that has already done most of what it is going to do."

"There has been a very significant tendency by investors to chase momentum."
