A rather indistinct one too. What does "This" refer to?
I'll guess that you are suggesting that instituttions are either (a) creating the current volatility so they can profit from it or (b) keeping the price from doing what it normally does going into ex-div.
(a) is more likely to be day traders who are trying to take out stops and then cover, but will probably cover before the close anyway, especially on Fridays.
(b) has happened to a series of REITs this quarter, including NCT and NRZ, which did a collective dividend increase in the quarter they split up, RSO, which went down before ex-div, up for a few days after, and is at about the same price now, and others. (b) has everything to do with fear of Fed actions that probably won't happen for years. For whatever it's worth, RAS is up since it announced its dividend. It just isn't up as much as one might normally expect given an 8% dividend increase.
