Why Houghton Mifflin Harcourt Stock Was Up Again on Friday
Shares of educational materials company Houghton Mifflin Harcourt (NASDAQ: HMHC) are on the rise Friday. Instead, the day's upward move appears to have been a continuation of Thursday's rise, which was cued by the company's announcement of some significant structural changes to its business. While it's impossible to say for sure what was causing Houghton Mifflin Harcourt stock to climb further Friday (since there was no new news), looking at the company's short interest suggests a reason.
