The subject of today's article is the BlackRock Science and Technology Trust (BST), a perpetual closed-end fund trading at a 2.12% discount to its net asset value and featuring a 9.80% trailing distribution yield. As with many CEFs, a managed high distribution yield is the key draw, which fund managers achieve with the help of premiums received from selling covered call options on individual securities. However, BST has struggled recently, declining by 3.02% in August and 7.40% MTD through September 24.
