A Costco employee of 9 years watched his sister shop for 45 minutes and spend $280.
He told her she overpaid by $112 and missed 7 things Costco members are entitled to that the store never advertises.
"Costco makes money on memberships, not margins. They built benefits into the membership most people never activate. That's the business model."
She thought Costco was a place you go to buy toilet paper in bulk and grab a rotisserie chicken.
He told her that's like buying a smartphone and only using it as a flashlight.
"You're paying $65 a year for access to a system. You're using 10% of that system. The other 90% is sitting there savings on prescriptions, free travel perks, price protection, services that compete with companies you're already paying separately and none of it is advertised on the shelf because Costco doesn't make more money when you use it. They make money when you renew."
He changed 7 things in her account, her shopping habits, and her mindset about the membership.
She saved $112 that trip. She's saved over $2,400 in the 14 months since.
Here are the 7 things he showed her:
NOBODY TEACHES YOU HOW TO ACTUALLY TELL IF A COMPANY IS A GOOD BUY.
Most people look at a low P/E, a hot sector, or whatever is trending here.
Here is the real process:
Hey Megan I played professionally for 7 years in the MLS & USL. I recently found out I’m actually a woman & would like to try out for the NWSL.
I will play for free & any jersey sales can be donated to charity.
Will you be inclusive to me & help me chase my dream?
As vezes eu acho que José Aldo não faz ideia do tamanho que ele tem mundo afora.
Ontem ele se encontrou com The Rock numa sessão, e achando que The Rock não sabia quem ele era, disse:
“Tenho um presente pra você, sou ex campeão peso pena do UFC”
The Rock no mesmo momento interrompe:
“Eu sei quem você é. Sempre que me perguntam quem são meus lutadores favoritos, eu digo Anderson Silva, José Aldo”
Kkkkkkkkkkkkkkkkkkkkk
The Rock só vive em eventos do UFC, muita inocência do Aldo achar que ele não saberia quem era um dos maiores lutadores de todos os tempos.
3 days ago I was warning. People paid attention.

GITHUB JUST CREATED AN OFFICIAL CERTIFICATION FOR THE MOST IN-DEMAND DEVELOPER ROLE OF 2026.
It is called Agentic AI Developer.
GH-600.
And it is the first formal signal that running AI agent teams is now a recognized engineering discipline with a credential behind it.
Not a prompt engineer.
Not a vibe coder.
An Agentic AI Developer.
The person who operates, supervises, and integrates AI agents across the entire software development lifecycle.
The person who knows where agents fail in production.
The person who understands how to build autonomous workflows that do not introduce catastrophic failure modes into CI/CD pipelines.
The person every engineering team is going to need and almost none of them have right now.
GitHub certifying this role changes the hiring conversation permanently.
Before GH-600: "Do you work with AI agents?" is an interview question with no standard answer.
After GH-600: the credential tells the hiring manager exactly what you know and what you can do before the interview starts.
The engineers who get certified in the first wave of GH-600 will have a credential for a role that has more demand than supply for the next 3 to 5 years.
The engineers who wait until it is mainstream will be competing with everyone who moved first.
If you are already working with GitHub Copilot or building agent-driven workflows you are already doing this job.
GH-600 is how you prove it.

A TON OF THINGS HAPPENED IN THE STOCK MARKET TODAY.
Here’s a full recap:
1. The $SPX S&P 500 and $QQQ Nasdaq closed at fresh all-time highs today, even with oil spiking and U.S.-Iran peace talks stalling. The market is basically saying AI earnings momentum is more important than geopolitical risk right now. The PHLX Semiconductor Index rose 2.6%, with semis now comprising 17% of the S&P 500.
2. The optical networking trade continues to gain momentum. $LITE Lumentum surged after being added to the Nasdaq 100, while peers like $COHR Coherent and $GLW Corning also benefited from the AI data center connectivity theme. This is becoming one of the clearest “picks and shovels” trades in AI infrastructure. $LITE Lumentum’s move matters because the market is realizing AI is not just about GPUs. It is also about optical transceivers, lasers, fiber, switches, power, cooling, copper, glass, and every bottleneck inside the data center stack. The AI trade is expanding from chips into the entire physical infrastructure layer.
3. $TSLA Tesla was in focus after the White House invited Elon Musk, alongside more than a dozen top U.S. executives, to join President Trump’s trip to China this week. The delegation includes Apple’s Tim Cook, and BlackRock’s Larry Fink with other executives from Goldman Sachs, Cisco, Mastercard, Citi, Meta, Micron, and more. The trip is expected to focus on U.S.-China trade and investment, potential Boeing aircraft purchases, agriculture, energy, and possibly extending the rare earths truce, making Musk’s inclusion important given Tesla’s exposure to China manufacturing, demand, and supply chains. Jensen Huang $NVDA and Lisa Su $AMD were not invited as per Reuters.
4. Oil jumped again as the U.S.-Iran situation remained unresolved, with Brent crude moving above $104 and the Strait of Hormuz risk still hanging over the market. This is the main bear case investors are watching: if oil keeps rising, inflation expectations can come back and pressure the Fed. CPI will be reported tomorrow with expectations of a 3.7% print, the highest in 2.5 years.
5. Per Jeffries: "47% of semis/hardware stocks are screening overbought on 14-day RSI (high was 70% in Dec '23, 66% on April 24) as of Friday's close. The SOX is now 60% above its 200-day moving average, a level not seen since March 2000 and July 1995."
6. Earnings season continues to come in strong. Reuters reported that 440 S&P 500 companies $SPX have reported, with 83% beating estimates and Q1 earnings growth now projected at 28.6% year-over-year. That is why the market keeps absorbing bad macro headlines.
7. $CBRS Cerebras increased its planned IPO price range as investor demand for AI chip exposure remains extremely strong. The company is now looking to sell 30 million shares at $150 to $160 each, potentially raising up to $4.8 billion. The AI IPO window is officially open again.
8. $CRCL Circle reported a 20% increase in quarterly revenue and reserve income to $694 million, helped by rising demand for USDC during a volatile period. USDC circulation grew 28% year-over-year to $77 billion, showing that stablecoins are becoming a bigger part of the financial infrastructure story.
9. The most traded options today were $TSLA with 5.5M contracts, $NVDA with 4.8M, $MU with 1.1M, $INTC with 1.0M, $AAPL with 1.0M, $NOK with 886K, $META with 637K, $AMZN with 621K, $MSFT with 591K, and $AMD with 514K.
10. $HIMS Hims & Hers reported Q1 revenue of $608M, up 4% YoY, with subscribers growing 9% YoY to nearly 2.6M. The company raised full-year 2026 revenue guidance to $2.8B-$3.0B, but profitability moved lower as gross margin fell to 65% from 73%, net loss was $92M, and adjusted EBITDA declined to $44M from $91M last year. Management said 2026 is a “defining year” as the company expands branded GLP-1 offerings, international markets, diagnostics, and technology infrastructure.
11. $ASTS AST SpaceMobile reported Q1 revenue of $14.7M and said it remains on track for full-year 2026 revenue guidance of $150M-$200M. The bigger story is deployment: BlueBird 8, 9, and 10 are expected to launch in mid-June, BlueBird 11 through 33 are already in advanced production, and the company is targeting roughly 45 satellites in orbit during 2026. ASTS also received FCC authorization for commercial SpaceMobile service in the U.S., hit 98.9 Mbps peak data speeds from an in-orbit satellite to an unmodified smartphone, and ended the quarter with about $3.5B in cash
12. China is also in focus ahead of a Trump-Xi summit, with Chinese stocks $BABA $KWEB $JD hitting an 11-year high and the yuan reaching a three-year peak. Investors are watching whether the U.S. and China could coordinate around trade, Iran, and global supply chains.
I used to do these recaps a year ago...have gotten a bit busy but looking to bring them back...would people like them at the end of the day? I use AI to help summarize the events but the real time (around 30-40 min daily) comes in curating the best headlines and including the relevant details. Happy to start it again if people want it back!
