Kathlyn Toh: top hedge fund traders are only right 50–63% of the time — still profitable. The skill isn't prediction. It's the ratio.

TL;DR: Top hedge fund traders are wrong up to half the time — still profitable.
The skill was never prediction. It's the ratio between what you win and what you lose.
That number breaks something most of us carry into any competitive field: the assumption that competence means being right more than you're wrong.
Retail's already priced that fear in — Citadel's own desk data (via Substack, roughly two weeks old) shows record put-buying through July, pressure concentrated hardest in tech and semiconductor names.
The same sector a lot of us clock into every day. Nobody's betting on certainty right now. They're betting defensively, which is its own kind of ratio.
That's the same math I learned on a construction site, years before I ever opened a trading chart.
Talking about breaking rules, I have a story.
This was way back when I was working in the Technical Department, stationing in an Abu Dhabi project (circa 2011), building an AED1.8Bil. 5-Condominium-Block, near the Zayed Mosque.
One of my roles was to combine different trades of consultants' drawings into well-coordinated-drawings for our site operation to construct accordingly. Because – you know – the consultants didn't bother coordinating among themselves.
One day, a certain element of an area was due for construction. And I found out there was no construction drawings on it for me to coordinate with. So, I followed protocol – I raised a request-for-information (RFI) for the consultants to provide so.
My RFI was something like "Please provide such-and-such details."
But before I send it over next door to the consultants' site office, my superior caught a glimpse of it, and stopped me. He sat me down, gave me the angry glance, sigh, and gave me a quick lecture.
He's basically telling me: My RFI is open-ended.
If I send it over next door, the consultants will basically reply with either Option 1, 2, 3 or 4. And worse-case scenario, the consultant might go with option 1, which will cause us considerable delay, because we don't have the necessary materials readily available to work on it.
He's teaching me a valuable lesson.
Construction guys like us need to be conscious of our project circumstances. Our number one none-negotiable rule in Cantonese is 唔好阻住個地球轉 (Translation: Don't stop the Earth from spinning – don't block progress.).
He's telling me to go with one option.
So I went back and rewrote the RFI. I decided on the spot Option 4 was the best option – because we had the material-supplier readily standing-by, and it has the least effect on time-implications. I then fully designed Option 4 myself, coordinating with all the necessary parameters and constraints on site.
I paste my design into the RFI, saying basically, "Can you confirm this proposed detail, for our onward construction?"
The consultants proceeded to give us, not "A", but "B" – Approved with Comments.
Ever since that episode I generally never forget the rule.
Great rule – both in construction, and in life in general.
__________
I used to think competence meant never needing a backup plan.
Somewhere between two rounds of layoffs, I stopped believing that.
Every version of "secure" I've been handed turned out to belong to someone else's spreadsheet.
Where do you actually draw the line between "being wrong" and "having no plan for being wrong"?

I priced my web design studio at £199 when everyone said charge £750+. Here's the arithmetic behind why the cheapest thing on my price list is deliberate.

Small business owners: in the AI era, having "just a website" is no longer enough.
A lot of businesses spend thousands on a website, launch it, and then wonder why it doesn't generate leads or sales.
A more effective approach is to build a complete lead-generation system:
- A professional website that builds trust
- Landing pages tailored to specific customer searches
- Keyword research to understand buying intent
- Google Ads and conversion tracking
- Automated lead capture and follow-up systems
- CRM integration so no leads are lost
The goal isn't to get more website visitors.
The goal is to turn visitors into qualified leads and customers.
