This is the right explanation for $DOCS climb AH yest, which may continue today. Doubt it holds past next week. https://t.co/pdg84pbJcm

I don't know what people expected for the $RKT print and guide. Always puts and takes, but this was a solid print in this environment. $UWMC just went through the windshield and my guess is that $RKT has some share gains to be had there. Gain on sale in the Pro channel was tight in the quarter so perhaps that reflects some of that.

@MoodyWriter13 Agreed, good quarter, excellent longer-term trajectory. Very happy to have a chunky position here. $INTR

@Tintincapital @29374736ahshsv @flippyfloppy52 @smurfkonto1 Ha, no worries. There were some real concerns around resource nationalism in Chile recently, especially with $SQM so that's understandable.

Megachips Corp 6875.T looking interesting given the +30% move on $SITM after earnings+forecast. Megachips owns more than its marketcap worth of SITM. (no debt, net cash). They've done some real buybacks recently too! Core biz is meh. Megachips is about ~¥140bn mcap.
