"What we got was a selloff and it happens every single time an event is happening.

Explanations please?"

You ask for an explanation, yet you gave the explanation above (bolded). 

I was suprised the tumble didn't start a bit earlier, as I thought I heard that at least some revenue producing items aren't really out there yet, and something about over the next quarter or two, etc.  I'll have to listen again, but there was nothing in the presentation that I thought would make the stock go up.

Yesterday, I would have been happy to hold our ground today, after a very impressive move on Friday.   However, the way it played out, the essentially no move day was a disappointment. 

Remember, I'm only speaking here in terms of share price action, the tech content of today's presentation remains pretty much Greek to my ears.  I listen to try to get a sense of the state of things, and the sense that I got, was it's going to take a bit longer than my sense was on Friday.  

Another overall sense of things tells me we will eventually get around to selling some meaningful amount of technological products.  

Let's see if any Rodman attendees do some buying tomorrow and in days to come, it's possible, but more likely that they will wait, but watch.
