$KLAR seems too easy… obviously recession=write-offs, but the value proposition to consumers would strengthen? What am I missing?

Everything is going right for Apes. Box office last month was an all time record. And the Apes can't get $AMC above $3 or should I say 30 cents before the reverse split. Only conclusion I have: Apes weak, Ken Griffin strong. Be like Ken Griffin.

Exploring SaaS survival in the agentic era — $PANW vs $DDOG. Both sit on critical telemetry. Both expose MCP. On paper they look alike. They aren’t. Model labs have a real reason to build their own observability collectors. Coding agents write and ship code; to get better they need production feedback. Own the host telemetry, close the loop. That same incentive is much weaker for cybersecurity endpoint agents. Finding beacons and writing better code are different jobs. Building a Falcon- or Cortex-class sensor estate is years of trust, labeled attacks, and compliance — not a natural side quest for a model lab. Then there’s the screen. Datadog doesn’t own where developers live. They already live in Cursor / Claude Code / Copilot. So those agents pull Datadog in over MCP. The data plane stays sticky; the UI gets shared. Palo Alto usually does own where the SOC lives. The shift starts in the security console — cases, playbooks, response. In a PANW shop, Cortex is the main workplace. Claude can sit on top in a multi-vendor stack. That’s the risk but not the base case. Same idea — agents need the pipes. What’s different is who tries to own the collector, and who already owns the desk. Thoughts welcome. Full Part 3 write-up for Convequity subscribers is on its way.
