Poet has a mkt. cap of about 78 million dollars.   For many companies in high tech, It is a small amount even with a 100% increase in the stock price.   A take over offer is always a possibility, and this has been discussed before, and the lower the stock price, the cheaper and easier.   Poet is obviously not ready to make a big announcement about the VCSEL.   I would think that if the VCSEL was up to specs, Poet would have announced it already.   I think such an announcement would drive the stock price much higher, and make a take-over more difficult.   There are hints that Poet has made some progress, but investors remain unconvinced, and want to see tangible proof.  This must be the case also for any Company looking at Poet (if there are any).   Only Poet management knows how close they are to unveiling the VCSEL, and if they are close, they would want to keep it quiet until they have absolute proof, or risk being taken out on the cheap.

That's the dilemma for investors to consider, and there are other questions as well.   Unfortunately, Poet didn't endear themselves to investors with the last financing deal, which cast doubts about the viability of Poet's technology.  

That's the way I see it.
