No, it's probably because we are near an equilibrium point. Shareholders don't want to let go of any more of their shares at this point in time, and buyers aren't willing to risk much money on shares at this point in time.
I doubt that we'll see another split in the immediate future, and I hope we don't. We need to get the share price moving up and to have the stock gain more visibility by listing on a major exchange like NASDAQ.
By the way, the O/S is always bought up. Meaning, someone is always the owner of every available outstanding share. They supposedly did the forward 3-for-1 split to introduce liquidity into the pool, so that there would be more trading volume. I think it's just fine right now, and what will really get the volume going is solid news.
Hopefully the time of the fluff PR is coming to an intermediate end.
Cheers
