Hello Led , Some of us have been in this play for 10 years plus , taking profits is a wise strategy however we have entered phase 3 ! Your a smart guy surely this new phase we are in must solidify a lot of concerns with this investment . YES YES nothing not this stock or any other is without risk ( Agreed ). However we in my opinion have turned the corner , new kidney research is going to excite a lot of new awareness as trial planning gets underway , orphan trails get underway , and in my mind zenith IPO launch ( if it comes to fruition ) I don't see flipping for few dollars is the wisest choice in the short term (just my opinion ) If first quarters milestones are not realized , then companies have failed us once again AND that would be most unfortunate ( still phase 3 IS STILL ONGOING ! ) I hope most here are in this till results are known as I wish all contributors here ultimate financial success , some may be looking for pennies I for one want large and multiple dollar increases before turning out for profits !!! So to Led and anyone thinking about selling ,first quarter holds a lot of magic for these two companies ( new money new investors will be made aware ) again the old adage " TIMING IS EVERYTHING !!!" Good luck / wisdom to all of us !!! Stock Happy holidays too ...
