$TMUS, $VZ, $T, teleco's continuing underperformance today after getting sold hard last week. GS last week blamed Instinct and Muse for the selloff given their ability to negotiate and cancel bills: "While US telcos traded down (TMUS -5.5%; AT&T-2% & VZ -3%) on concerns on X chatter around Meta’s Muse and rival AI agent Instinct has focused on their new ability to make outbound calls to U.S. businesses, including negotiating phone and cable bills on behalf of users. This could become a risk for telcos because AI agents can wait on hold, escalate with support teams, switch users to cheaper plans, remove add-ons and claim credits at scale—potentially increasing pressure on ARPU, retention economics and customer-service costs. The same risk applies to European names as these AI assistant role out. But its NOT just telcos as other industries could also face pressure -industries most at risk are those with recurring bills, negotiable pricing, confusing add-ons, high churn incentives and customer-service friction—including cable/broadband, insurance, utilities, banks/credit cards, subscriptions, travel, healthcare billing, retail returns, auto leasing and gyms. If AI agents can persistently call, wait on hold, compare offers, cancel services, claim credits and renegotiate terms on behalf of customers, companies that rely on inertia or under-claimed discounts could face higher retention discounts, lower add-on revenue, more support volume and weaker pricing power. PS – have been using Instinct for a week of so – its pretty impressive once you get past the hesitance of giving access to parts of your life (not brave enough on a bank account) – book restaurants, tennis courts, highlight must read emails – its also picks up inaccuracies of emails and sources what is inaccurate." - GS Sean Johnstone

Copart $CPRT just acquired $ACVA for $1.9B. The filings came out on the 17th, and I've spent 12 hours a day analyzing everything since. I read so much my eye drops stopped cutting it, had to switch back to vitamin A for the dry eyes. As usual, the reality is way more complicated than anything I've seen on social media so far. I break it all down, and what it means for my Copart thesis. Have fun. (Link in bio/below.)
