It's always puzzled me why RVX is not on Nasdaq? Any ideas?

Cityslicker,

Fundamentally, a lack of confidence. imo

Techinically, they would have needed to maintain a $5 share price (USD) in order to satisfy listing requirements or perform a reverse stock split.  It was an announced plan. They hired Rothschilds to guide them.  I guess the BOM results deflated their confidence to move forward.  Getting and maintaining a Nasdaq listing is expensive too.  So securing a massive cash injection first would help a lot.

I don't understand why they didn't reassert an intent to list the moment they received FDA Breakthrough Therapy Designation.  Money I guess.  That would have seriously emboldened investors sentiment and would have had a positive effect on the share price.   Maybe even enough to naturally keep the SP above $5.  It probably would have lit a fire under any acquiring BP, not wanting to see the SP take off on them. 

It may not be too late if they strike a partnership deal with upfront cash infusion.  They should move heaven and earth to make a US listing happen somehow.
