I find it pretty hard to work out why this is valued at 10x less than 4DX to be honest, and they have just raised $35m at massively higher market cap.

lung diagnostic vs heart diagnostic
lower current revenue
yet to have CPT codes in place (we have CPT codes)

the stock market is a funny place. At this point it would be great just to get the cap raise out the way and get on with commercialisation. Even if they raised $25m at current price at least it would put a floor under the SP and would be all up from here
