"BEST EXPLANATION on Options hands down!!"
Let's face it - options trading can be confusing.
That's why I put together this free report that explains it using cartoon stick figures:
I've been teaching options to regular people since 2001, and this is easily my most popular training of all time.
Here are a few comments from my readers:
"BEST EXPLANATION on Options hands down!!"
"Best explanations i've seen on the net so far! great job!"
"This was so so helpful. The cartoons helped and then all of the sudden, the formal definition just clicked! Thank you!!"
"Bill Poulos is the first to explain call and put options in a language I understand."
"I’m not even done... and the explanation is so good I had to comment. Dude you are a great teacher."
This report sells for $29.97 on my website, but today, you can download a copy for free.
The only catch is that the download link will expire, and when it does, you'll have to pay full price on my website.
P.S. This is my #1 most popular options trading report. Normally $29.97 on my website, but free via this backdoor download link:
| What’s Surprising |
China has the fastest computer on Earth and the fourth-most computers on the list. LineShine, in Shenzhen, runs 2.198 exaflops — about a fifth faster than America’s El Capitan. It uses no American chips. All 13.79 million of its cores are custom Chinese LX2 processors.
China listed 227 machines in November 2019, more than any country in the world. It lists 31 now. Chinese institutions largely stopped submitting results. This ranking counts what a country discloses, not what it owns.
Two of the ten fastest computers belong to an oil company. Eni’s HPC7 is 6th at 571 petaflops and its HPC6 is 8th at 477. Together they clear an exaflop, and no other company on the list holds more computing power.
| What’s Not Surprising |
The United States has led this count for most of the years since the list began in 1993, and it leads on power too: 37.5% of the combined performance of all 500 machines. Three of the top four systems are American, and all three belong to the Department of Energy.
The rest of the top ten is rich and mostly small. Japan 44, Germany 41, France 21, South Korea 19, Italy 18, Canada 17, then Britain and Taiwan tied at 11. Only China and Taiwan sit outside the OECD.
Forty-seven countries hold at least one of the 500. Africa holds two, one in South Africa and one in Morocco. Brazil, Australia, South Africa and Argentina have 16 between them. Germany alone has 41.

The next list comes in November. Two things to track. Whether China submits a second exascale machine — one entry now carries almost all of its listed performance. And whether the American count keeps falling: about 172 in late 2024, 171 a year later, 161 in June. The European Union sits 30 systems behind. We’ll be watching. |
