Sunam Co. tumbled as much as -21%, extending Tuesday’s -30% slide.

South Korean stocks that had skyrocketed on perceived links to superconductors fell for a second day Wednesday after a US university research center rebutted recent claims of a breakthrough in the technology.

Sunam Co. dropped as much as -21%, extending its -30% slide Tuesday after the post from the University of Maryland’s Condensed Matter Theory Center. Duksung Co. and Mobiis Co. similarly declined for a second day.

The stocks had surged since Korean researchers last month said they had created the world’s first superconductor able to conduct electricity at room temperature and ambient pressure, using a material called LK-99. The long-sought technology promises to revolutionize industries from computing to power, if it actually works.

While the post from the University of Maryland’s Condensed Matter Theory Center threw cold water on the recent stock frenzy, the head of the institute left the door open to disagreement.

“Could I be wrong? Of course, anyone can be wrong,” Dr. Sankar Das Sarma, director of the center, said in an email to Bloomberg News. “I do not think that the subject ends today even if LK-99 has no SC,” he said, “but I will be paying no attention to the topic any longer.”

Meanwhile, the Korean Society of Superconductivity and Cryogenics said it is proceeding as planned with its own validation process on the claims.

About a week ago, a paper was released about a new material called LK-99, which some scientists claim can be used to create a room-temperature and pressure-ambient superconductor.

If this is true, we are witnessing the biggest physics breakthrough of our lifetimes.

I am not a physicist but I know this would be a HUGE deal.

We lose 3 nuclear reactors worth of electricity each year to the friction inherent in electricity transmission. Superconductors fix this by enabling lossless electricity transmission.

However, superconductors are currently impractical due to their need of extremely low temperatures and high pressure.

This new paper claims that LK-99 can be produced in 34 hours with extremely basic lab equipment.

Basically, it would make everything in technology much better.

It’s still unclear whether the scientist’s findings are legit, as the paper was not peer-reviewed, and many conduction experts are casting doubt on the paper’s claims:

But there are definitely some encouraging signs that this thing is for real:

I'm expecting for new news to come out soon.

WLD token will be distributed weekly to those who scan their iris with their “Orb” device.

2 million people have scanned already. Worldcoin is not available in the U.S.

A WorldID is also generated with the iris scan.

CEO Alex Blania argued that iris scanning was necessary, because the main alternative was KYC with documents, but half the world's population doesn't have them.

Cannabis producers have been awful investments. But there's reason to believe it can get better.

The “green rush” in cannabis stocks has turned to a crushing disappointment, with the largest plays down more than 90%.

Canopy Growth has collapsed below $1 — and yet it does seem like, somehow, the company should be able to salvage some value. $CGC

Tilray looks like a winner if the Canadian industry finally becomes rational, but that day may never arrive. $TLRY

Cronos is seeing takeover interest, but a deal seems unlikely. Should CRON plunge, deep value investors should take a good look. $CRON

32 people with a collective $2.2 million dollars can't be wrong!

$PYPL owns Venmo, the app Supreme Court aids take payment on (allegedly)

Why it matters:

Several lawyers who have handled cases before the Supreme Court, including one who successfully argued for the elimination of race-based affirmative action at colleges, sent money to a top aide of Justice Clarence Thomas, according to the aide's now-private Venmo transaction history. (But the Venmo history was initially set to public. Nice)

I was surprised to see Domino's is going to do a delivery partnership with UBER that allows customers to order food through Uber Eats/Postmates with actual delivery from DPZ drivers.

I like this development because it provides some more delivery options.

Domonos has had a long-held policy of not working with delivery app companies. But this has hurt them because a lot of sales get rung up on mobile apps instead of Domino's directly.

No Domino's menus will be listed on Uber Eats' and Postmates' food-delivery apps across 28 of Domino's markets, including the U.S., U.K. and Canada.

This shows a lot of strength from Uber too, because the world's largest pizza chain just validated their control over a vital channel of ordering their product.

US users will no longer be able to trade $ALGO.X, $MANA.X, $DASH and $MATIC.X

This certainly appears to be in response to the SEC's lawsuit of Coinbase. And Gary Gensler should be pleased that his plan is working. By going after one exchange, the others are self regulating and falling into line.

Coinbase however is digging their feet in and operating "as usual" until the suit plays out.

It's early, but so far the SEC is winning

$ADA.X, $MATIC.X, and $SOL.X were all named as securities by the SEC when they sued Coinbase. Now Robinhood is delisting them.

$HOOD isn't a crypto-native business, they were just riding the wave.

Given they've had issues with regulators in the past, it doesn't make sense for them to fight this battle from a business perspective.

First off, I want to say that I don't smoke. So you can say I don't know what I'm talking about... but you CAN'T say I'm high.

Here's why $SHOP is a logical way to bet on the marijuana industry:

Shopify has always been early to the cannabis game. When Canada legalized recreational marijuana, Shopify partnered with the Ontario Liquor Control Board to allow the use of its e-commerce platform to buy and sell newly legal cannabis products. In fact, in the first day cannabis was legalized, Shopify's platform held its own against the hundreds of thousands of orders placed and millions of visitors that suddenly flooded into the market.

And Ontario is just the beginning. Canopy Growth $CGC and its extremely popular Tweed brand of cannabis, Aurora Cannabis (TSX: ACB), and Hexo (NYSE: HEXO) — all use Shopify's e-commerce platform. Those are three of the world's largest licensed producers of cannabis.

Crucially, Shopify's platform is regulation compliant, allowing all retailers and producers to stay within the bounds of the law.

Companies want to build their own brands instead of hitching on as third-party suppliers. On Shopify they can do that. On Amazon, they can't. $AMZN

Shopify has set itself up at the center of cannabis e-commerce not only in Canada but in the U.S. as well. Shopify has expanded its platform in the U.S. to allow the sale of hemp-derived cannabidiol (CBD) products, opening up an entirely new cannabis market to fuel revenue growth far into the future.
