Stock market showing “bubble-like sentiment”

Markets were mixed on Monday.

The S&P 500 rose 0.4 percent and the Shanghai Composite rose 0.5 percent. However, the STOXX Europe 600 fell 0.8 percent.

“I do think we've been in a euphoric state in the market for awhile, and now that the election settled and congress is in place, a lot of the good news has already been priced in,” said Tom Martin, vice president and senior portfolio manager at Globalt.

Indeed, many analysts are seeing signs of a stock market bubble.

“Pockets of the market have recently demonstrated investor behavior consistent with bubble-like sentiment,” Goldman Sachs analysts led by David Kostin wrote in a note.

Still, that may not deter investors.

“Equity bubbles are not delicate,” said Robert Buckland, Citi equity strategist. “They take some stopping.”
