Buy
25,000 shares
$101,460
Significance 4/10

Director Mario Gabelli buys 25,000 GGT shares at $4.06; adds 2.2% to 1.16M-share position

Gabelli Mario J, a director of Gabelli Multimedia Trust, purchased 25,000 shares at $4.06 on 2026-02-24, increasing his holdings from 1,133,396 to 1,158,396 shares (a net increase of 2.2%). The transaction occurred at a price 2.1% below the current market price of $4.15 and 17.1% below the 52-week high of $4.90. Across his open-market history at all tickers, Gabelli's prior 20 purchases averaged a 30-day return of +3.2% and 90-day return of +2.5%, with a 50% win rate over 90 days. Given the modest portfolio addition, current price momentum (flat on the 30-day), and his mixed historical batting average, this buy warrants ordinary monitoring but does not signal exceptional conviction.

Significance 6/10

Director Mario J Gabelli buys 4,500 shares of GDV at $29.09; holdings rise 22.0% to 25,000 shares

Director Mario J Gabelli purchased 4,500 shares of GABELLI DIVIDEND & INCOME TRUST (GDV) at $29.09 on 2026-02-17, increasing his holdings by 22.0% from 20,500 to 25,000 shares. This is the third open-market purchase at GDV in three months: a prior buy on 2026-01-27 and another on 2025-11-18 (which returned +9.8% over 90 days). The stock is currently trading at $29.17, near its 52-week high of $29.23, and has advanced 11.4% over the past 90 days. While Gabelli's cross-ticker buy record shows a 50.00% 90-day win rate with average gains of +2.5%, the concentrated pattern of three consecutive purchases at GDV within a short window—combined with measurable gains following the November trade—suggests sustained accumulation at favorable valuations rather than reactive trading.

Buy
5,500 shares
$157,946
Significance 7/10

Director GABELLI MARIO J bought 5,500 shares of GDV at $28.72 on 2026-01-27 ($157,945.70); +36.7% increase in holdings amid cluster buying by 2 other insiders within 14 days.

Director GABELLI MARIO J purchased 5,500 shares of GABELLI DIVIDEND & INCOME TRUST at $28.72, expanding his stake from 15,000 shares to 20,500 shares (+36.7% increase in holdings). The transaction occurred near the stock's 52-week high of $28.73, and is notably part of a cluster buy pattern with 2 other insiders acquiring shares within the past 14 days. Across his cross-ticker track record, the insider has executed 20 prior open-market buys with a 100.00% 90-day win rate and average 90d return of +3.8%, though same-ticker history at GDV shows only 1 prior measurable trade (2025-11-18, +3.1% 30d return). The recent 90-day price appreciation of +6.1% and positive 30-day momentum of +2.8% suggest the broader timing environment has been favorable for the stock.

Buy
4,810 shares
$46,080
Significance 6/10

Director Gabelli purchased 4,810 shares at $9.58 across 2 transactions, nearly doubling stake to 10,000 shares

Director Mario J Gabelli executed 2 separate purchases totaling 4,810 shares for $46,079.80 on 2026-01-12, increasing his holdings from 5,190 shares to 10,000 shares—a 92.7% increase in position size. The shares were purchased at $9.58, slightly below the current price of $9.61, placing the execution near the recent 30-day trading window (+1.8% change) and well below the 52-week high of $10.42. His cross-ticker track record shows 20 prior buys with an average 30-day return of -0.2%, while his prior two purchases at GRX (most recent on 2026-01-08 and 2025-12-03) have mixed measurable outcomes, with the December transaction showing a -0.5% 30-day return. The significant share accumulation at a measured price point warrants attention to whether this represents a material shift in the director's conviction at this specific holding.

Buy
990 shares
$9,484
Significance 4/10

Director Gabelli buys 990 shares of GRX at $9.58, raising stake to 9.0K shares; stock currently $9.57.

Director Mario J Gabelli purchased 990 shares at $9.58 on 2026-01-08, increasing his holdings from 8,000 shares to 9.0K shares, representing a +12.4% increase in position size. The transaction occurred at a price near the current market level of $9.57, and within the 52-week range of $8.96–$10.42. His cross-ticker track record shows 20 prior open-market buys averaging -0.2% 90-day returns, while his three prior GRX trades (including two subsequent buys on 2026-01-12) show limited measurable outcomes, with one prior buy on 2025-12-03 posting a -0.5% 30-day return. The transaction size is modest at $9,484.20 and represents a discrete addition rather than a concentrated directional move in the fund.

Buy
1,800,000 shares
$18,000,000
Significance 8/10

Director Gabelli buys 1,800,000 shares at $10.00 in 4 transactions for $18,000,000.00

Director Mario J Gabelli executed 4 separate purchases totaling 1,800,000 shares for $18,000,000.00 at $10.00 per share on 2025-12-26, moving his holdings from -1,700,000 shares to 100,000 shares post-transaction. This substantial $18.0M deployment represents a significant capital commitment on a single trading day at a consistent price point. Gabelli's cross-ticker track record shows 20 prior open-market buys with an average 90-day return of +4.7% and a 66.67% win rate, providing historical context for his pattern of identifying entry points, though this metric reflects performance across multiple holdings rather than specific performance at GRX.E.

95,387 shares
$453,088
Significance 6/10

10% owner GABELLI MARIO J bought 95,387 shares of LGL at $4.75 on 2025-12-30, raising stake to 572,324 shares (+20.0%).

GABELLI MARIO J, a 10% stakeholder in LGL Group Inc, purchased 95,387 shares at $4.75, representing a 20.0% increase in his holdings to 572,324 shares. The purchase occurred at a price 17.4% below the current price of $5.75 and 38.9% below the 52-week high of $7.76, suggesting the transaction took place during a period of relative weakness for the stock. The company's fundamentals show recent strength: annual revenue growth of +16.7% and net income of $772,000.00 on quarterly revenue of $1,108,000.00, though the P/E of 33.82 reflects premium valuation relative to earnings. Notably, across his open-market history on all tickers, GABELLI's prior 20 buys averaged a 30-day return of -2.0%, indicating his historical purchases have not consistently captured subsequent short-term gains. This transaction's long-term significance will depend on whether the company can sustain its revenue growth trajectory and justify its current valuation multiple.

Buy
5,818,500 shares
$58,185,000
Significance 8/10

Mario Gabelli (Director) purchases 5,818,500 shares at $10.00 for $58,185,000 in GDV.M on 2025-12-26

Director Mario Gabelli executed 4 separate purchases totaling 5,818,500 shares for $58,185,000 at $10.00 per share on 2025-12-26, moving his holdings from negative 468,500 shares to a positive 5,350,000 shares. This represents a substantial capital commitment and reversal from a short or net-short position to substantial long ownership. Gabelli's cross-ticker track record shows 20 prior buys with a 66.67% 90-day win rate and average 90-day returns of +3.7%, indicating a historically disciplined acquisition pattern across investments. The multi-transaction structure and uniform $10.00 price point warrant examination of whether this reflects a negotiated block purchase, private arrangement, or systematic accumulation strategy at the fund's NAV or a predetermined price level.

Buy

$1,000,000
Significance 4/10

Director Gabelli buys 100,000 shares of GRX.G at $10.00 for $1,000,000.00; holdings reach 1.50M shares

Mario J Gabelli, a Director, purchased 100,000 shares (100.0K shares) of Gabelli Healthcare & WellnessRx Trust at $10.00 on 2025-12-26, increasing his holdings from 1.40M shares to 1.50M shares. This represents a 7.1% increase in his position size. Notably, Gabelli's cross-ticker track record shows 20 prior buys with an average 90-day return of -2.0%, indicating a pattern of purchasing near local peaks or ahead of price declines. At GRX.G specifically, this is only the second open-market transaction visible in the SAME-TICKER HISTORY, following a buy on 2025-10-30 whose outcome remains unmeasurable. The absence of measurable outcomes on prior trades at this ticker limits direct assessment of his execution timing in this fund, though the negative cross-ticker average suggests caution.

$6,675,000
Significance 4/10

Director GABELLI MARIO J buys 667,500 shares at $10.00 in 2 transactions for $6,675,000.00

GABELLI MARIO J executed two separate purchases totaling 667,500 shares at $10.00 on 2025-12-26 for $6,675,000.00, moving his position from -500,000 shares to 167,500 shares post-transaction. However, the insider's cross-ticker track record reveals a concerning pattern: 20 prior buys with an average 90-day return of -5.0% and a 0.00% win rate, indicating a systematic pattern of purchasing ahead of price declines. While the substantial dollar commitment may reflect conviction in the security, the historical timing pattern warrants scrutiny of the fundamental or technical backdrop that prompted this acquisition.
