"I assume Jacobs exit is going to take place through placements rather than a takeover." 3/3

Sirin @sirindude.bsky.social · 15d

"The reason Jacobs hired turnaround specialist Peter Feld was most likely to boost the share price for an eventual exit. The parallels with KKR’s investments in WMF and GfK cannot be ignored and are probably bullish, longer-term." 2/3

Maybe you are banned for knowing too much.

Here is the text I mentioned:

"30% shareholder Klaus Jacobs has been selling down his stake gradually, most recently between 2019 and 2021 when the stock traded above 20x EV/EBIT." 1/2

Just read this writeup and the author mentioned the jacobs planned exit, but was sure it would be placement.

Anyone else find Swiss public transport pricing unnecessarily complicated?

- GA Travelcard (simple but CHF 4,000)
- Point-to-point travelcards
- Half Fare Plus with the prepaid reload discounts
- Or sticking with regular Half Fare Travelcard

@nonzerosumjames.bsky.social Hey, do you by chance have a blogpost or podcast episode on effective altruism or similar?

(if sold July 17, '25) - 259$ (206.5 CHF).
return -> 313%
time -> 20.6 months
annualized return -> 127% cagr

A worse exchange rate, lower interest in my specific item and missing out on the initial sale lowered my return.

The sold price in March was 259$ (228.56 CHF).
return -> 357%
time -> 16.6 months
annualized return -> 209.6% cagr

Since then I have relisted the item and lowered the price back to 259$. But with USD down significantly since then, the current price in CHF would be:

CSGO/CS2 investing - exhibit 1

In late October '23 I bought this arguably good looking, but objectively very rare skin from a friend for 50 CHF.

In March '25 sold the item sucessfully on csfloat (skin for cash platform), but stupidly missed the notification email.

The transaction was cancelled.
