CNBC Daily Open: Worries over Iran and Fed independence weigh on markets

The battle for Britain’s investment trusts

In the world of U.K. quoted companies, investment trusts are frequently disparaged as a sleepy backwater, a dull corner of the market offering little excitement.

But there is no debate at present; the sector is currently very newsy because of one individual, the U.S. activist investor Boaz Weinstein, founder and chief investment officer of the hedge fund Saba Capital.
