Corporate insiders just bought $8.3 billion in their own company's stock in a single week. Sells: zero. Not a misread. 487 individual insider buys. Zero sells. Across every sector except oil. Two weeks ago those same insiders were dumping. $19.4 billion in sells. Zero buys. The complete opposite signal. Something changed in the last 14 days that made hundreds of CEOs, CFOs, and board members reach into their personal accounts and buy millions in stock. All at the same time. With nobody selling. Insider buying at this scale has happened four times in the last 20 years. March 2009. The bottom of the financial crisis. Insiders bought aggressively while the public was panic selling. The S&P 500 was at 666. It hit 1,500 within two years. 125% gain. December 2018. The Fed tightening panic. Insiders bought into the selloff. Market ripped 30% over the next 12 months. March 2020. COVID crash. Insiders bought at the bottom while CNBC was running death count tickers. Market doubled in 18 months. Now. April 2026. After the largest single-week tariff shock in modern history. Insiders are buying everything. These are the people who see the Q2 order books. Who sit in the boardroom when guidance gets discussed before it's public. Who know whether their company's revenue is accelerating or decaying before anyone on Wall Street runs the model. When one insider buys, it could be anything. Compensation plan. Tax optimization. Charity commitment. When 487 insiders buy and zero sell in the same week, they're telling you something. They're telling you with their own money, which is the only signal that matters. What I'm doing right now. Following the cluster. When insiders buy across an entire sector simultaneously, the sector outperforms the market by 8-12% over the next 6 months historically. I'm watching which sectors had the heaviest concentration of buys this week and adding exposure there. The energy sector exclusion is interesting. Insiders are NOT buying oil. Every other sector saw aggressive buying. Oil saw nothing. That tells me insiders expect energy to underperform relative to the market even if the market recovers. Possibly a ceasefire signal in Iran that hasn't hit the headlines yet. The market is always changing and you don't have the time to track it. I've decided to run a 100% FREE webinar to discuss market moves and how to adapt and make money from real world events. Link is in comments.

$RKLB CEO @Peter_J_Beck just voluntarily signed up for a significant shift in compensation > Elimination of cash salary SPB reduced his annual base salary from its previous level to just $1.00 (minimum required by New Zealand law) This is often seen with founders like Elon Musk to signal that they are not draining company resources > Forfeiture of Bonuses and RSUs SPB has waived all rights to annual bonuses and voluntarily canceled 392,155 RSUs Beck is essentially walking away from MILLIONS of dollars in guaranteed future equity to keep those shares off the company’s books Because he is giving up cash and unvested stock, his personal wealth is now almost entirely tied to the performance of the shares he already owns. He only wins if the stock price goes up significantly over the long term. SPB is a class act and very aligned with shareholders bullish

The G.O.A.T, Peter Beck, reduces salary to $1 and removes eligibility for annual bonuses. Also cancelled $20M in RSUs (To cover Venus?) 😯 $RKLB

Some of the highest quality businesses in the world are trading at extremely cheap prices. Ignore the MSM. One of the most one-sided wars in history that will end well for the U.S. and the world. And we have the potential for a large peace dividend. One of the best times in a long time to buy quality. Ignore the bears.

$5,000 an hour. for sunlight. from space. a startup putting 50,000 mirrors in orbit to sell sunlight anywhere on earth I thought this was the dumbest idea Ive ever heard then it clicked - firefighting aircraft get GROUNDED every night at sunset. pilots cant see terrain. fires burn unchecked for 10 hours straight. and heres whats wild - water drops are 60% more effective at night. cooler temps. less wind. but nobody can fly. light up the fire line from orbit. let them work. the US spends $3-5B a year fighting wildfires. this is a rounding error. - a single late frost in Napa or Florida citrus can wipe out an entire season. $854M in frost losses last year alone. but the crazy part - the real buyer isnt even the farmer. its the crop insurance company trying to avoid a $500M payout by spending $50k on a few hours of orbital sunlight - fog costs London Heathrow over $100M a year in delays. fog burns off when sunlight hits the ground. you speed that up by 30 minutes and the value per hour is $500K-$1M. $5k/hour is pocket change - military forward operating base at night? forget night vision goggles. just light up the whole compound from space and go get it - 4 million people above the Arctic Circle live in MONTHS of total darkness. depression. productivity drops. everything slows down. you could give entire communities twilight during polar night - 150,000 babies die or get brain damage every year in developing countries from jaundice because the cure is literally just light and they dont have electricity for it. beam it down from orbit. no power grid needed. I went down this rabbit hole for an hour and every use case is more insane than the last 260,000 people from 157 countries on the waitlist. each dropping $1,000-5,000. Sequoia backed them - first space investment since SpaceX. the Air Force already signed a contract. mirrors weigh 35 lbs and theyre the size of a basketball court. 4-10x brighter than a full moon. built by a 28 year old ex-SpaceX engineer. this went from "dumbest thing Ive ever seen" to holy shit in about 10 minutes...

🚨 THE LARGEST INVESTOR ON EARTH JUST SILENCED THE AI BUBBLE CROWD BlackRock CEO Larry Fink controls $14 trillion in assets. Every Fortune 500 CEO reads his letter before breakfast He just said this in his latest BBC interview: 1. “This is not a bubble” Fink talks directly to hyperscaler CEOs. Their message: demand is outpacing supply. Not slowing. Accelerating. They can’t build fast enough. 2. One data centre = $50 billion A single 1GW AI data centre costs over $50 billion. One tech CEO told Fink he needs 23 gigawatts by 2030. That’s over $1 trillion. From one company. 3. China is building 100GW of nuclear. Right now. That’s 30+ nuclear power stations under construction. While Europe debates planning permission, China pours concrete. 4. The real bottleneck isn’t chips. It’s power. “The biggest issue that limits the West is the cost of power.” His words. Not mine. 5. AI will create a blue-collar boom Fewer analysts. More technicians (e.g. electricians, welders, plumbers). The people who build and maintain AI infrastructure will be in massive demand. 6. Energy pragmatism, not ideology Oil. Gas. Solar. Nuclear. Wind. Use everything. Cheap power = economic resilience. Expensive power = recession. The largest investor on Earth just told you exactly where the money is going. AI infrastructure demand is real and accelerating. Only constrained by power.

Engineering job openings are at the highest levels we’ve seen in over 3 years There are over 67,000 (!!!) eng openings at tech companies globally right now, with 26,000 just in the U.S. We don’t know if there would have been more open roles if not for AI or if AI is actually leading to more open roles, but since the start of this year, the increase in open eng roles is accelerating even more.

STATE OF THE PRODUCT JOB MARKET IN EARLY 2026 In spite of the headlines about layoffs and AI taking jobs, we’re actually seeing a lot of promising signs in tech hiring, and some interesting new trends: 1. PM openings are at the highest levels we’ve seen in over three years 2. AI hasn’t slowed the demand for software engineers (at least not yet) 3. AI roles in general are absolutely exploding 4. Design roles have plateaued 5. The Bay Area is increasing in importance 6. Remote work opportunities continue to decline 7. Despite ongoing layoffs, the overall number of tech jobs continues to grow More in 🧵

It genuinely breaks my brain to imagine what 1400 hours of annual sunshine must be like to live in. When going to college in Chicago, I really struggled with the seemingly endless gray of the winters. Chicago gets 2500 sunshine hours!

Jensen is really good at looking into the future. Whenever I hear bears spread FUD about Nvidia I take a listen to Jensen 😊
Anish Moonka@anishmoonka

September 2009. Jensen Huang walks onto a small stage at the Fairmont hotel in San Jose. About 1,500 people are in the room. He runs a company that makes chips for video games. He spends the next 8 minutes doing math on a whiteboard, explaining why the future of computing won't come from making CPUs faster. He calls it "CEO math" and apologizes in advance to every computer science professor in the audience. Then he lays out an argument that almost nobody took seriously at the time: the way to make computers dramatically faster is to pair a regular CPU with hundreds of tiny parallel processors, the kind that already exist inside graphics cards. One CPU for the sequential stuff. Hundreds of GPU cores for everything else. He calls it "heterogeneous computing." He shows the math. A workload that can be split into many pieces at once gets up to 200x faster on this combined system. A workload that has to run one step at a time loses nothing. "The most important thing in creating a new architecture," he says, "is to make sure it does no harm." This was the first GPU Technology Conference. NVIDIA had launched a software platform called CUDA three years earlier, in 2006, to let developers write programs that run on graphics cards instead of just regular processors. Almost nobody cared. GPUs were for rendering Call of Duty, not for scientific computing. The academic world was polite but skeptical. The enterprise world ignored it entirely. By this point, Huang had been making this argument for years. NVIDIA was a $7 billion company. It competed with AMD and Intel for market share in the graphics market. That was the whole business. Jensen kept saying the GPU wasn't just a gaming chip; it was a computing platform. He kept saying parallel processing would reshape every industry from medicine to finance to physics simulations. People kept nodding, then doing nothing. Then deep learning happened. Around 2012, AI researchers discovered that training a neural network, which means teaching a computer to recognize patterns by running the same calculation millions of times across huge datasets, was exactly the kind of workload Jensen had been describing. GPUs can train AI models 10 to 50 times faster than CPUs. The architecture he outlined in this 2009 talk, with one CPU handling step-by-step tasks while hundreds of GPU cores crunch through massive amounts of parallel data, is now the literal blueprint for every AI data center on earth. ChatGPT runs on NVIDIA GPUs. Claude runs on NVIDIA GPUs. Gemini, Llama, Midjourney, nearly every major AI model you've heard of was trained on NVIDIA hardware using CUDA, the software platform Jensen built for a market that didn't exist yet. NVIDIA was worth about $7 billion when Jensen gave this talk. It is worth over $4.4 trillion today. That's a 600x increase. Jensen Huang, who founded the company at a Denny's in 1993 with two friends, now has a net worth of over $160 billion. He made Forbes' list of the 10 richest people for the first time this year. GTC 2026 is currently ongoing. 17,000 people are packing a hockey arena to watch the same guy explain what comes next. In 2009, 1,500 people showed up at a hotel ballroom, most of them for gaming graphics.
