IAC Stock: When Will Barry Diller Finally Unlock the Hidden Billions? The holding company is still trading near the combined value of its stake in MGM and its cash reserves, which could present an exceptional opportunity for patient investors.

IAC is one of the weirdest mispricings in my portfolio.
MGM + cash explain most of the value.
The rest is still being ignored.
That is exactly why I remain bullish.

In terms of revenue, Uber is eight times bigger than Lyft, but its enterprise value is 30 times higher. Is this a fair premium for the market leader? While I don't think Uber is overvalued, I see Lyft as a bargain at those prices. $UBER $LYFT

Von über 8 Mio. Jugendlichen in D sollen angeblich weniger als 4% süchtig nach Social Media sein. In welcher Parallelwelt lebt diese "Experten"-Kommission? Ich beobachte in meinem Umfeld jedenfalls etwas anderes. Und ihr so? buff.ly/uYn1r9Y

When Former High-Growth Stars Turn into Share-Cannibals How tech companies are buying back their own shares - and why this could be one of the most underrated sources of returns for investors.

Everyone’s worried about AI disruption of SaaS and platform companies. Meanwhile, management teams are buying their own companies at single-digit FCF multiples. That’s not fear — that’s conviction. Here are some examples from my portfolio: $PYPL $LYFT $MNDY $UPWK buff.ly/UVFZy4m

SpaceX-IPO: Wie Elon Musk die Nasdaq-Regeln zu seinen Gunsten verbiegt Wenn Börsen nicht mehr Preise finden, sondern Nachfrage organisieren – und Kleinanleger am Ende die Rechnung zahlen.

SpaceX wird der größte IPO aller Zeiten. Doch der Börsengang ist ein Skandal:
- verkürzte Wartezeit für den Nasdaq-100
- keine harte 10%-Free-Float-Hürde mehr
- das bedeutet Kaufzwang für ETFs und benchmarknahe Fonds
Ich halte das für brandgefährlich: buff.ly/D4v3mpD

Leider hat Elon es mit dem SoaceX IPO auch die ETF Sparer abgesehen. open.substack.com/pub/hightech...

SpaceX IPO: How Elon Musk Is Manipulating Nasdaq Rules to His Advantage What happens when stock exchanges no longer determine prices, but instead organize demand, and retail investors end up paying the bill?

The SpaceX IPO could become a historic example of how modern markets work:
-first create the scarcity,
-then accelerate index inclusion,
-then let ETFs and benchmark-driven funds do the buying.

That may be brilliant strategy for Elon.
But it is a dangerous precedent.

Twilio Stock: Why I Sold After a +100% Gain Twilio delivered strong results in 2025, including more growth, profitability, and free cash flow. Yet, I still sold the stock after it doubled in price for a good reason.

My exit from Twilio does not reflect a lack of confidence in the company’s operational performance. On the contrary: Twilio had a strong year 2025. My $TWLO exit is the result of a sober assessment of valuation and growth quality. buff.ly/GHBNMXv

IONOS Aktie: Ist das einer der spannendsten Tech-Werte Europas? Warum ein vermeintlich langweiliger Hosting- und Cloud-Anbieter genau die Mischung aus Wachstum, Margenhebel und Cashflow liefert, die ich aktuell suche.

Die IONOS Aktie wirkt auf den ersten Blick fast langweilig. Und genau das macht sie interessant: 6,6 Mio. Kunden, hohe wiederkehrende Umsätze, steigende Margen, starke Cashflows – dazu eine europäische Cloud-Story, die in den kommenden Jahren deutlich an Relevanz gewinnen könnte. buff.ly/iPNeb0f

UiPath After Q4 FY2026: Strong Operational Performance - But the Market Remains Skeptical The numbers are solid, but the guidance is disappointing. Can UiPath return to high growth as an "execution layer" in the AI era?

In 6 months UiPath went from $12 to nearly $20… and back to $12.
For a moment the market priced $PATH as an AI winner. Then the hype got erased.
I break down the Q4/FY26 numbers, FY27 guidance, valuation — and a plausible takeover optionality. 👉

With so many AV partnerships announced by Uber over the last couple of weeks, it's not easy to keep track of them all. This one with Nvidia could be very significant: the aim is to roll out the project globally in 28 cities across four continents by 2028. buff.ly/S064zqE

PayPal After the Stripe Rumors: Is this the Beginning of a Sale Process? Venmo, PSP, and Branded Checkout: How a breakup could reveal PayPal's intrinsic value.

In light of Stripe's interest buying PayPal, the CEO's dismissal finally seems understandable. Alex Chriss was not replaced due to poor quarterly results, but because the board wants to prepare for a potential sale or breakup of PayPal. Here's what shareholders of $PYPL can expect: buff.ly/VtAJMW7
