This final note today, in which reports of a tech bubble may turn out to have been greatly exaggerated. Remember yesterday’s big IPO? Pandora, the streaming music service. Shares had a nice little bump, then closed about 10 percent above the opening price.

Yeah, not so much anymore.

Investors apparently realized the company has never made any money. Shares down 23 percent today. They’re now almost $3 underwater from yesterday.
