$CSTL Took a long position. This is quite undervalued relative to the genetics testing industry. -Product has almost no competition in their niche indications. -Huge beat on top and bottom lines. -Huge increase in guidance. Growth is real and solid. -Multiples are too low considering they are close to profitability and generating positive free cash flow. -Low short interest = shorts know this is going much higher. $XBI $IBB

$LUCD I listened to the $CSTL call. One of the analysts asked about Esopredict, the Previse sponge on a string device. The answer was: -Castle has protocols worked out for cell collection -Expect an update 1H 2027 So they are WAY behind, not going to be a competitor to EsoGuard for many years, if ever. Cell collection has always been the fatal flaw of the sponge on a string device because the sponge gets contaminated on the way back out, plus you have to sit and sit there and wait for the capsule to dissolve while the string is just hanging down your throat. Detachments have historically been a problem as well. Not sure why they are even bothering with it. EsoGuard is absolutely the only option for non-invasive, fast screening.

$CSTL what did I miss here? Looks like revenue grew for all tests except SCC (which was expected due to prior loss of coverage). EBITDA was a loss of $5M, which isn’t great. But, revenue guidance was raised slightly. What is the critical thing(s) causing this to get pummeled?
