BlackRock Science & Technology Term Trust (NYSE:BSTZ) is a closed-end fund (CEF) that combines a venture-stage technology portfolio with a covered call writing strategy to deliver monthly income. With shares near $23 and a monthly distribution of $0.1625, the fund currently yields roughly 8.3%.
How a closed-end fund differs from a standard ETF
BSTZ is a closed-end fund with a fixed term expiring in 2031, at which point it liquidates at net asset value (NAV). Shares currently trade at a discount to NAV, meaning buyers get a built-in cushion and a known liquidity event at full value.
The fund generates income through two mechanisms. First, it holds equity stakes in publicly traded and private technology companies. Second, it writes covered calls on public holdings. A covered call means the fund sells the right to buy shares it owns at a fixed price, collecting a premium that becomes shareholder income. The tradeoff is capped upside when positions rise sharply.
Unlike a standard ETF, BSTZ can own private companies. Top holdings as of late March 2026 included Databricks at 16.17%, PsiQuantum at 6.37%, and NVIDIA at 6.36%, with Lumentum among the top names. Over 30% of the portfolio sits in private, illiquid holdings, which amplifies both growth potential and valuation uncertainty.
Distribution history and the shift to level payments
The distribution has compressed notably. Monthly payments ran at roughly $0.22 per share through most of 2025, then dropped to $0.1625 by late 2025 and have held there through the first three months of 2026. That decline reflects BlackRock’s September 2025 decision to shift from floating-rate to level-rate distributions, providing stability but also narrowing yield from the 12% range seen in mid-2025 to the current 8% range. Investors who bought at lower prices during 2025 are earning double-digit yields on cost basis. Those buying today receive roughly 8%. Distributions are sourced from option premium income, net investment income, realized gains, and occasionally return of capital. Return of capital is not inherently problematic in a CEF structure, but investors should monitor whether NAV is eroding over time.
Public holdings driving premium income
Because BSTZ relies on covered calls written against public holdings, the health of those positions directly affects premium income. Higher volatility generates richer premiums. Key public names include NVIDIA, Lumentum, Celestica (NYSE:CLS), and Microchip Technology.
NVIDIA (NASDAQ:NVDA | NVDA Price Prediction) is the fund’s most prominent public holding and a strong contributor to covered call premium income given its volatility. Q4 FY2026 revenue hit $68.1 billion, up 73% year over year, with free cash flow of $96.6 billion for the full fiscal year. NVIDIA pays a minimal dividend of $0.01/share, so its contribution to BSTZ’s income comes almost entirely through option premiums. The stock has risen 75% over the past year, which supports premium income but also means the fund has given up some appreciation when calls were exercised.
Lumentum (NASDAQ:LITE) has been one of the most explosive performers. Shares are up 143% year to date and more than 1,500% over the past year, driven by surging demand for optical components in AI data center interconnects. Q2 FY2026 revenue grew 66% year over year to $665.5 million, with operating income up 225%. Lumentum pays no dividend, so its value to BSTZ is entirely through price appreciation and option premiums. The stock’s extreme volatility makes it a rich source of call premium income.
Microchip Technology (NASDAQ:MCHP) is the one holding that pays a meaningful dividend. Microchip has paid $0.455 per share quarterly for the past five consecutive quarters, a rate it maintained even through a severe semiconductor down-cycle. Q3 FY2026 free cash flow came in at $318.9 million, up 26% year over year, providing solid coverage. CEO Steve Sanghi stated the company’s focus is on “maintaining our dividend commitment as we return to growth.” With forward EPS guidance of $0.48 to $0.52 for the next quarter, the $0.455 quarterly dividend sits within the guided earnings range.
Private holdings and valuation risk
The private holdings, led by Databricks at over 16% of the fund, cannot be written against with covered calls and contribute no option premium income. Their value is purely capital appreciation, which flows through NAV and can eventually support distributions when positions are exited or taken public. These holdings are marked to model, not to market, which means stated values may not reflect actual sale proceeds.
The fund’s NAV discount has historically ranged between 8% and 11%, providing a margin of safety for current buyers. If BSTZ liquidates at full NAV in 2031 as designed, today’s discount becomes a bonus return on top of distributions.
Total return and insider activity
BSTZ shares are up 58% over the past year and roughly 6% year to date. Investors collecting the 8% yield have also benefited from meaningful price appreciation. Portfolio manager Kim Tony made a notable insider purchase of 41,825 shares in February 2026 at roughly $22 per share, signaling internal confidence. Activist investor Saba Capital Management has accumulated a 7.94% stake, typically signaling a push for improved shareholder value or a discount-narrowing campaign.
What the 8% yield actually rests on
The 8% yield is backed by a diversified income engine: covered call premiums from volatile tech names, securities lending income, and realized gains. The distribution cut from $0.22 to $0.1625 has already occurred, so the current level is the stabilized baseline. The shift to level-rate distributions reduces the chance of another surprise reduction.
Primary risks are the private portfolio’s illiquidity and valuation opacity, tech sector cyclicality, and the covered call structure’s tendency to cap upside in a strong bull market. The 2031 term expiration forces a NAV realization that perpetual funds never provide.
BSTZ combines tech exposure, monthly income, and a built-in discount-to-NAV buffer through its 2031 term structure. Investors evaluating the fund should weigh the illiquid private holdings and covered call upside cap against the stabilized 8% distribution and known liquidation date.
