$SE is down -45% over the past few months. The prevailing bear case seems to hinge on two points: 1) Rising fear of TikTok Shop competition, and 2) Shopee reinvesting more heavily into logistics, capping margins at ~0.7% of GMV this year vs. prior expectations of ~1.2%. The concern is that this spend is defensive - a necessary response to TikTok rather than a choice. But alt data is telling a different story. TikTok Shop’s Southeast Asia GMV growth has slowed materially over the past few quarters - from 70%+ in 2Q25 to ~30%+ by late 2025. That’s only modestly above Shopee’s own growth rate. More notably, TikTok’s relative share vs. Shopee in Indonesia (~50% of regional GMV) has effectively flat-lined over the past year. If this data is directionally right, Shopee’s ~50 bps of reinvestment looks discretionary and offensive -widening the moat - rather than a defensive reaction to competitive pressure. And critically, that implies the margin compression is temporary, not structural. Oh, and both Shopee & Tiktok are raising take-rates. Not usually the sign of a competitor trying to aggressively take share... Curious, what am I missing? Is the -45% drawdown really just “2026 margins down > negative 2026 earnings revisions > stock down,” even if margins are likely to re-expand next year? And Shopee emerges with a wider moat after? The competitive backdrop looks like it’s improving, not deteriorating...

It's always amazing for me to see $expe stock getting pummelled evertime there is AI disruption related sell off in the market. Expedia is a platform, for an AI app to replace it, one will need to build something equivalent, get all the hotels to list it there (as inventory) and manage the bookings. Not that it can't be done but it's not same as replacing a SaaS company. Instead I see Expedia using AI to navigate the change. It's more likely that AI replaces how users find hotels on Expedia vs via google search now than the former happening. Also, it's a super recession proof business model. Time will tell for sure :)

Going thru PennyMac earnings... why is this not bullish for Rocket Mortgage $RKT? $PFSI is down on accelerated prepayments, and lacking the capacity to recapture them. Meanwhile $RKT's been embracing AI / tech to grow capacity per loan officer, and not needing additional headcount in the next cycle. $RKT also has 80% recapture rate, so their own MSR business should be protected. What are the odds these refinancing's flowed to $RKT, and they meaningfully grew market share this quarter? Am I missing something?
