Boaz Weinstein, the hedge fund investor on the winning side of JPMorgan Chase’s $6.2 billion, “London Whale” trading loss in 2011, is now taking on index fund giant BlackRock.
On Friday, Weinstein‘s Saba Capital detailed in a presentation seen by CNBC its plans to push for change at 10 closed-end BlackRock funds that trade at a significant discount to the value of their underlying assets compared to their peers. Saba says the underperformance is a direct result of BlackRock’s management.
The hedge fund wants board control at three BlackRock funds and a minority slate at seven others. It also seeks to oust BlackRock as the manager of six of those ten funds.
“In the last three years, nine of the ten funds that we’re even talking about have lost money for investors,” Weinstein said on CNBC’s “Squawk Box” earlier this week.
At the heart of Saba’s “Hey BlackRock” campaign is an argument around governance. Saba says in its presentation that BlackRock runs those closed-end funds the “exact opposite” way it expects companies to run themselves.
BlackRock “is talking out of both sides of its mouth” by doing this, Saba says. That’s cost retail investors $1.4 billion in discounts, by Saba’s math, on top of the management fees it charges.
BlackRock, Saba says in the deck, “considers itself a leader in governance, but is crushing shareholder rights.” At certain BlackRock funds, for example, if an investor doesn’t submit their vote in a shareholder meeting, their shares will automatically go to support BlackRock. Saba is suing to change that.
A BlackRock spokesperson called that assertion “very misleading” and said those funds “simply require that most shareholders vote affirmatively in favor.”
The index fund manager’s rebuttal, “Defend Your Fund,” describes Saba as an activist hedge fund seeking to “enrich itself.”
The problem and the solution
Closed-end funds have a finite number of shares. Investors who want to sell their positions have to find an interested buyer, which means they may not be able to sell at a price that reflects the value of a fund’s holdings.
In open-ended funds, by contrast, an investor can redeem its shares with the manager in exchange for cash. That’s how many index funds are structured, like those that track the S&P 500.
Saba says it has a solution. BlackRock should buy back shares from investors at the price they’re worth, not where they currently trade.
“Investors who want to come out come out, and those who want to stay will stay for a hundred years, if they want,” Weinstein told CNBC earlier this week.
Weinstein, who founded Saba in 2009, made a fortune two years later, when he noticed that a relatively obscure credit derivatives index was behaving abnormally. Saba began buying up the underlying derivatives that, unbeknownst to him, were being sold by JPMorgan’s Bruno Iksil. For a time, Saba took tremendous losses on the position, until Iksil’s bet turned sour on him, costing JPMorgan billions and netting Saba huge profits.
Saba said in its investor deck that the changes at BlackRock could take the form of a tender offer or a restructuring. The presentation noted that BlackRock previously cast its shares in support of a tender at another closed-end fund where an activist was pushing for similar change.
At the worst-performing funds relative to their peer group, Saba is seeking shareholder approval to fire the manager. In total, BlackRock wants new management at six funds, including the BlackRock California Municipal Income Trust (BFZ), the BlackRock Innovation and Growth Term Trust (BIGZ) and the BlackRock Health Sciences Term Trust (BMEZ).
“BlackRock is failing as a manager by delivering subpar performance compared to relevant benchmarks and worst-in-class corporate governance,” the deck says.
If Saba were to win shareholder approval to fire BlackRock as manager at the six funds, the newly constituted boards would then run a review process over at least six months. Saba says that in addition to offering liquidity to investors, its board nominees would push for reduced fees and for other unspecified governance fixes.
A BlackRock spokesperson told CNBC that the firm has historically taken steps to improve returns at closed-end funds when necessary.
“BlackRock’s closed-end funds welcome constructive engagement with thoughtful shareholders who act in good faith with the shared goal of enhancing long-term value for all,” the spokesperson said.
Weinstein said Saba has run similar campaigns at roughly 60 closed-end funds in the past decade but has only taken over a fund’s management twice. The hedge fund sued BlackRock last year to remove that so-called “vote-stripping provision” at certain funds and filed another lawsuit earlier this year.
BlackRock has pitched shareholders via mailings and advertisements. “Your dependable, income-paying investment,” BlackRock has told investors, is under threat from Saba.
Saba plans to host a webinar for shareholders on Monday but says BlackRock has refused to provide the shareholder list for several of the funds. The BlackRock spokesperson said that it has “always acted in accordance with all applicable laws” when providing shareholder information, and that it “never blocked Saba’s access to shareholders.”
“What we want is for shareholders, which we are the largest of but not in any way the majority, to make that $1.4 billion, which can be done at the press of a button,” Weinstein told CNBC earlier this week.

NVIDIA founder and CEO Jensen Huang speaks during the NVIDIA GTC Paris keynote, part of the 9th edition of the VivaTech technology startup and innovation fair, held at the Dôme de Paris in the Porte de Versailles exhibition center in Paris on June 11, 2025.

Nvidia CEO Jensen Huang sold another 225,000 shares of the chipmaker, totaling about $37 million, according to a U.S. Securities and Exchange Commission filing.
The sale comes as part of a plan adopted in March for Huang to sell up to 6 million shares of the leading artificial intelligence company. Huang began trading stock last month. His most recent sale, disclosed last Friday, totaled 225,000 shares, or about $36 million.
Since he began selling stock this year, Huang has unloaded 1.2 million shares, totaling about $190 million, according to InsiderScore. In last year’s prearranged plan, Huang cashed in over $700 million.
AI demand and the need for graphics processing units powering large language models have spiked Huang’s net worth and propelled Nvidia past a $4 trillion market capitalization, making it the most valuable company.
That surge in value has put Huang above Berkshire Hathaway’s Warren Buffett in net worth on Bloomberg’s Billionaire Index.

In another significant win, Nvidia said this week that it plans to soon restart sales of its H20 chips to China after the Trump administration indicated that it would approve export licenses.
Earlier this year, the administration said Nvidia would need a license approval to ship the chips, designed specifically for China.
“The U.S. government has assured NVIDIA that licenses will be granted, and NVIDIA hopes to start deliveries soon,” the company said in a statement Tuesday.
Huang said during a press conference on Wednesday in Beijing, China, that he wants to sell chips more advanced than the H20 to China at some point.
Huang wasn’t the only stakeholder to unload Nvidia shares. Board member Brooke Seawell sold $16 million worth of stock.

Nvidia is looking to ship more advanced chips to China than its current generation, CEO Jensen Huang said on Wednesday, as he looks to revitalize sales in the world’s second-largest economy.
The comments come after Nvidia said on Monday that it will resume sales of its H20 artificial intelligence chip to China, reversing a previous ban. The H20 is a less-advanced semiconductor designed for AI workloads that comply with U.S. export restrictions to China.
“I hope to get more advanced chips into China than the H20,” Huang said during a press conference in Beijing, China, in response to a CNBC question.
“And the reason for that is because technology is always moving on … today Hopper’s terrific but some years from now we will have more and more and better and better technology, and I think it’s sensible that whatever we’re allowed to sell in China will continue to get better and better over time as well,” he said referencing Hopper, Nvidia’s chip architecture that the H20 is built on.
Nvidia has been caught in the crosshairs of U.S.-China tensions over trade and technology. The tech giant has faced several rounds of restrictions that have forced it to restrict access of its most advanced chips to China. In response, Nvidia has developed semiconductors that comply with export restrictions, such as the H20.
Nvidia took a $4.5 billion writedown on the unsold H20 inventory in May and said sales in its last financial quarter would have been $2.5 billion higher without any export curbs.
Huang has trod a fine line between praising U.S. President Donald Trump’s policies regarding reshoring chip manufacturing to America while also lobbying for change on curbs to China.
The Nvidia boss has argued the Chinese AI market could be worth $50 billion in the next two-to-three years and that it would be a “tremendous loss” for American firms not to be part of that. Huang also told CNBC this year that Nvidia’s Chinese rival Huawei has “got China covered” if U.S. firms can’t participate in the market.
“Export control are things that are outside of our control and they can be quite disruptive to our business. It is our job only to inform the governments of the nature and the unintended consequences of the policies that they make,” Huang said during his visit to Beijing.
Nvidia has also laid out a roadmap to release more advanced chips, though it remains unclear if the U.S. government would allow Nvidia to sell more advanced products to Chinese companies. However, U.S. Commerce Secretary Howard Lutnick suggested on Tuesday that the government would continue to allow chip sales to China so that companies in the market rely on American technology.
“The idea is the Chinese are more than capable of building their own,” Lutnick told CNBC. “You want to keep one step ahead of what they can build, so they keep buying our chips.”
