BUBBLE ECONOMY: Long Island Iced Tea shares went gangbusters after changing its name to Long Blockchain.

Up until this morning, Long Blockchain was a little-known company making non-alcoholic lemonades and ice teas. As of Wednesday, the company had a market value of just $23.8 million, but at one point in pre-market trading had 9.76 million outstanding shares, giving the company a market value of close to $138 million. That’s small by Wall Street standards, but significant considering the only factor seemed to be the name change.

Caveat emptor.
