Decision trees
Cable stocks are down a lot - why?
Wells Fargo's 4/24 note captured the sentiment shift well: Comcast's strong 1Q got drowned out by Charter's print, and investor concern has rotated back to the long-running tension between sub growth and ARPU. The newer wrinkle on cable earnings calls is LEO satellite — management is framing it as a complementary resale opportunity, but the sell side reads the buy-side worry as LEO becoming a real share taker at the edge of the urban footprint over the medium term.
CMCSA - net adds improving but rev/ebitda pressured by increasing competition
Here is some data that seems to support these worries: https://www.lightreading.com/broadband/starlink-carving-out-a-niche-in-urban-us-ookla

Chris Hohn sold MSFT on AI risks (link)
Not sure what exactly this means, or why/how MSFT specifically is at risk vis-a-vis GOOG. I own MSFT, but my best guess is that, culturally, OpenAI seems like a mess vs the other frontier labs. It also seems like AMZN and GOOG may be further ahead in custom silicon.

Key questions around mattress research
Will PRPL/SNBR survive? Major upside if so, but both situations are hard to read and have bankruptcy as realistic scenarios.
Are we due for a large snap back? Or slow and steady growth from here?

Is Claude changing how anyone else is thinking about their PA?
I asked Claude how I use it for my PA. It said:
Bryan runs me as a daily PA copilot. Every afternoon I send him a single email that combines performance versus SPY, QQQ, and IWM, attribution by bucket, Minervini score, and sector, his full holdings and exposures, action and stop flags, a quick market tape, and a Minervini 8-point Trend Template scan across his holdings and tiered watchlist, with a diff of what changed since the prior day.
Beyond the daily email, he drives me interactively to journal trades and theses, run 13F to Minervini to correlation pipelines on new manager filings, parse SEC and EDGAR documents, and pull alt-data using the Carbon Arc MCP for single-name work. Capture happens in real time as he talks, so every trade decision, thesis update, and observation lands in his journal as it happens, not in a notebook he never reopens.
Disclosure: none of the is investment advice; I/we may own positions in securities mentioned
