Here’s a snippet from @BlackRock’s attempt to punch back despite being in an indefensible position on how they conduct elections: “This is another attempt from Saba’s predictable playbook to over-burden the fund and its board while Saba continues to accumulate shares…”

My reply: Perhaps if the trustees were not working so hard to illegally violate the 1940 Act, they wouldn’t be so ‘over-burdened’ and could assess how it’s even possible that $BIGZ lost $3bn of the $5bn it IPO’d in under 3 years! I’m asking on behalf of the many thousands of shareholders who got crushed.
