Undiscovered Compounders on X

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.)

Serenity on X

The main duo $SKHY and Samsung are having a fun day. I'm still long memory (eg. $EWY / $DRAM ) since if capacity agreements extend 3-5 years... and your analysts model 2.8-3.3x 2027E. Risk/reward is attractive over time. But I think legacy memory a very interesting trade currently due to ASP hike potential.. It also just so happens these same companies procure memory from even smaller memory companies (that might have higher sensitivity)... So if you want to, you can track $PSMC wafer allocations, and find some interesting companies that likely replace $MU discontinued legacy memory through Alliance or supply directly to Samsung. Won't mention them on X, but just throwing out some research ideas.

Serenity on X

The internet is now cooked soon? With $RDDT to other social media like X more at risk due to AI. You can have new decision models like Jev making autonomous computer interaction at near $0 cost. (With actions becoming more human-like/adapative) Then LLMs outputs influencing behavior or leading conversations. So at scale, a malicious actor can spawn 50,000,000 bots just roaming the internet, with LLM prompts convincing people + manufacturing public opinion. The main bottleneck would be phone number, IP, account age, maybe hardware for compute + device identifiers (which is extremely cheap still)… rather than LLM cost. I’ve already anecdotally seen short sellers use AI bots to spread negative misinformation about companies like $SIVE. Or bots market ____ account as the best one to follow in the comments. Or as seen with X uncovering 200+ bots manipulating debate about datacenter public opinion. But the scale might be exponentially worse soon. Scary to think about.
