BlackRock Science and Technology Term Trust (NYSE:BSTZ) has attracted income-focused investors with a yield that has ranged between 8% and 12% depending on when you bought it. But the yield number alone does not tell the full story. The real question is whether the income engine behind it can hold up, and the honest answer is: the distribution has already been cut once and the income sources that fund it are constrained.
How BSTZ Generates Its Income
BSTZ is a closed-end fund, not a traditional ETF, and that distinction matters. It holds a portfolio of technology-oriented companies, both public and private, and generates income through two primary mechanisms: covered call premiums on its public equity holdings and securities lending income. The fund also benefits from capital gains on its holdings, which flow through its managed distribution plan. The catch is that when income and gains fall short of the target distribution, the fund can make up the difference with return of capital, meaning it pays investors back their own money (a return of capital, which pays investors back their own money) rather than earned income.
In September 2025, BlackRock transitioned BSTZ from floating rate distributions to level rate distributions, stating the goal was to “enhance stability and maintain competitive distribution rates” while offering “potential for Net Asset Value growth.” That shift stabilized the monthly payment at $0.16 per share through early 2026, down from the $0.21 to $0.22 range paid through most of 2025.
A Distribution History That Shows Real Cuts
The dividend history here is not reassuring for income purists. In early 2024, the monthly payment was cut roughly 37%, dropping from around $0.21 to the $0.103 to $0.105 range from January through April. It recovered by mid-2024, but the episode demonstrated that management will reduce the distribution when the income engine cannot support it. The current $0.16 monthly rate is itself a step down from 2025 levels, and one report noted a further 0.2% decrease recently.
The Private Holdings Problem
The most structurally concerning element of BSTZ’s income story is its private portfolio. Over 30% of the portfolio is in private holdings, including companies like Databricks and ByteDance. Private holdings carry two risks that directly threaten distribution sustainability: they cannot easily be sold to fund distributions, and their valuations are estimates, not market prices. The fund’s stated NAV may not reflect what those assets would actually fetch in a sale, which is likely why the market has persistently priced BSTZ at a discount, reaching 11% below NAV in early 2026.
Activist investor Saba Capital disclosed a 7.94% stake in March 2026, having acquired roughly 5.5 million shares for approximately $93.8 million. Activist involvement in closed-end funds typically signals pressure to close the NAV discount, which could mean structural changes ahead.
Total Return Context
The price performance has been strong over the past year. Shares rose 58% over the trailing twelve months, reaching around $24, outpacing the Nasdaq-100’s 37% gain over the same period. Over five years, though, the share price has gained only about 5%, which is a reminder that the income has come partly at the cost of price appreciation relative to the broader tech index.
Distribution Sustainability: Structurally Challenged
BSTZ’s distribution is not safe in the traditional sense. It has been cut before, it includes return of capital components, and the private holdings that make up a third of the portfolio create genuine valuation and liquidity uncertainty. The current $0.16 monthly rate is stable for now, but it rests on a covered call strategy that caps upside and a private portfolio that cannot be easily monetized. Investors who understand closed-end fund mechanics, are comfortable with a 2031 liquidation timeline, and treat the income as a secondary benefit to the NAV discount opportunity may find this fund worth considering. Investors who need a dependable, growing income stream should look elsewhere.
