At +50% passive, it's crazy, but if it ever reaches 85%, it'll be interesting to see what that means.

Right now, value investing still works for stocks not included in major indices. For those in the top 100, the P/E ratio has become useless.

Tonight after 6 years online, I turn off my service, and it goes open source.

MiCA regulations leave no room for small companies:

The cost of compliance grew 4x every 2y, and now hits previously unregulated businesses.

Tomorrow I start again.

If your earning power is becoming obsolete faster than you can re-skill, then the traditional "grind salary → diversify into bonds → retire at 65" strategy leaves you exposed. janklosowski.substack.com/p/the-windo...

I'm slowly becoming an index investing doomer:

The idea that most people invest in 500 companies they can't even name just because other people do it is crazy.

It works as long as everybody buys, but when the market reverses: who's the buyer on the other side?

When traditional wealth-building paths feel blocked (real estate/wages/pensions), gambling becomes a rational hope trade:

If you can't save your way to security, maybe you can get lucky.

The expected value is terrible, but it's better than no value at all.

Silver is not Bitcoin.

Mining is now extremely profitable, and the supply side has to change. Silver is not that scarce. At $14, it was simply unattractive to mine. At $80, miners are in a rush.

The chart doesn't say that GPT started doing those jobs in 2023.

It's a paradigm shift.

Companies hire for the future. The GPT launch was a seismic shock, that adjusted roadmaps.

Even if not fully implemented, AI is now on everybody's roadmap.

The irony of the housing market is that while today we discuss affordability as the biggest problem, in 30 years we may see those apartments paid back with sweat, blood, and tears standing empty. janklosowski.substack.com/p/the-50-ye...

For years I was telling people: don't worry about quantum computing until $GOOGL starts changing their cryptography to post-quantum.

This year they started.

46.5% of S&P 500 companies have at least one warning sign.
56 companies have 3+ warning signs.

The idea of index Investing is to outsource analysis to others. The problem starts when the majority of investors outsource, without realizing they’re now those who create the market.

The key concept here is "risk/reward ratio."

How likely is it that silver will never be lower?
At this point, what is more likely: 2x up or 2x down?

Silver is not Bitcoin, and supply is not finite.

The current global fertility rate is 2.25. This is how many kids the average woman has. As long as this rate is no smaller than 2.1—the replacement level—the population will be growing, and that’s the demand side of the real estate market. janklosowski.substack.com/p/the-50-ye...

You'll be amazing at predicting $MSTR price if you understand what it is:

It's a leveraged Bitcoin without margin calls.

🇪🇺 EU bans US ETFs.

Why?

EU wants ETFs to project future performance (KID) using language that, according to US law, would expose them to litigation risk.

Yes, the US gets the market and the EU doesn't.

Result:

You can't buy a safe ETF, but you can buy risky CFDs on it.

Even 30-year mortgage makes you asking question about how the real estate market may look like in 30 years.

The current prediction is that by the year 2050, even the global average will already be below 2.1: janklosowski.substack.com/p/the-50-ye...

There are 4 robotics ETFs: $ROBO, $BOTZ, $ARTY, $IBOT

Currently underperforming the S&P, but trending up. I plan to dive deeper into their holdings. I'm likely not aware of most of those companies, especially from Asian markets. For now, the tiny $IBOT has my attention.

Bitcoin ETFs stole some volume, but don't compete with $MSTR directly. Most people get the "exposure to Bitcoin" part, but they miss the main value proposition:

Leverage without a margin call.

Is insider trading on prediction markets a good thing?

If the goal is accuracy, this is exactly what you want.

The gambling vs information framing likely misses the nuance that not all markets are the same: a meteorologist betting on the weather is not the same as a guy betting on his own divorce.

There was no COVID vaccine for cinema theaters.

Apparently, going to the cinema was just a social habit that, once forcefully stopped, never found its way back in the digital economy.

According to this chart, investors shouldn't expect any returns from the S&P 500 in the next decade. Bitcoin in every portfolio.

"Flight to assets" makes traditional fundamental techniques like relying on P/B ratios useless.

Buffett-era readings:

- <1.0 → Undervalued or distressed
- 1.0-3.0 → Normal (banks, industrials)
- 3.0-5.0 → Premium quality businesses
- 5.0+ → Extremely expensive

The biggest misunderstanding about $MSTR is how it fails. It's NOT insolvency. The debt could be fully paid back with just 24% of the Bitcoin holdings.

Bonds and preferreds are risk-off.

The entire risk is carried by common stockholders. janklosowski.substack.com/i/179412331...
