Winston Score History

The full picture

BlackRock Science and Technology Trust (BST) is a closed-end fund managed by BlackRock, the world's largest asset manager. It invests in stocks of science and technology companies, focusing on businesses involved in areas like software, semiconductors, internet services, and healthcare technology. The fund's goal is to give everyday investors access to a diversified portfolio of tech-focused companies they might not easily build on their own.

BST makes money by charging an annual management fee on the assets it holds, which is typical for funds like this. It trades on the New York Stock Exchange like a regular stock, and its portfolio is heavily weighted toward large U.S. tech companies, though it also holds some international names. The fund uses an options strategy called covered calls to generate extra income, which helps support its dividend payments to shareholders. The main risk is that a broad downturn in technology stocks would directly reduce the fund's value and could pressure its ability to maintain its dividend.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
