The Non-linear Economics of Grocery Delivery Basket
Instacart’s larger grocery baskets create disproportionately better delivery economics than DoorDash’s, making half the basket size worth far less than half the profit.

$PLUS Accelerating, sales -14% y/y in Q2, noted Q3 not improving yet implied FY guide is for flat sales (downward revisions to come). Margins benefitted from 1-time financing segment gain-on-sale. Still trading at a premium to higher quality industry leader CDW, makes zero sense.

$AS 50x P/E levered retail roll-up w only one decent asset (Arc’teryx). Stagnating in the US, nearly fully-penetrated in China. >$500 jackets didn’t work for $GOOS in Asia. Arc already bigger. Hyper promotional mgmt sent the stock skyward. This is going to be an epic crash.

$CVGW In MRQ benefited from temp avocado price spike and 1-time F/X add-back. Volumes have been declining LDD for the last 3Qs ($CMG shifting suppliers). DOJ investigation continues. Prices & earnings reverting lower. Commodity distributor trading at 30x P/E is not sustainable.

$DAKT New $50M display upgrade award for the Miami Heat arena. Will be a nice boost to current quarter earnings (FQ2'25). https://t.co/sLAFBEerYi

$NX Just acquired peer Tyman. >3x leverage, never done a deal before, commodity business, customers all cutting numbers w deteriorating resi remodel activity ($AMWD yesterday, $MBC, $OC, $JELD). Stock is trading at close to 14x EPS. Seen this movie before. Earnings next week.

$CVGW USDA crackdown on Mexican avocado corruption significantly erroding import vols (region where $CVGW sources all product). S. America taking share at accelerating rate as customers (ie. $CMG, grocers) shift suppliers. $CVGW sales vol -13% MRQ. Current Q could be a disaster. https://t.co/KJgK8fXbM4

$PLUS Earnings on 8/5, expectations & stock disconnected from reality. Suppliers ($CSCO – 50% of product sales), competitors & customers all reporting sharp sales declines. Non-event PR today re a service they’ve been offering for 3 yrs is pumping stock; suggests mgmt is grasping

@Mike10947310 $CVGW Sources >90% of its avocados from Michoacan, MX. $CMG purchases ~10% of tot US avocados. Its latest ESG report noted “diversifying away from Mexican suppliers.” This latest drama down there will almost certainly accelerate sourcing away from $CVGW, etc.
