Roscon - you raise an interesting point - the volume that comes from day traders is clearly crucial to keeping the MMs on the straight and narrow and is what changes their behaviour during the intermittent periods of rerating. Once the day trading volume evaporates the MMs can get away with running long term short positions, especially when backed by tame sellers or warrant holders as they have generally been here.
The question of whether all trading is intrinsically bad and inimicable to LTHs or just trading that feeds on and encourages SP volatility is a subtle one.
There is clearly a style of trading, let us call it active damping, which helps to suppress excess exuberance in the share price and which turns shares in cash that can then be used, as Ophidian and others did yesterday to damp out the excesses of any shorting stupidity - this type of trading actually reduces SP volatility and firm's up shareholder's beliefs in the fundamentals of the company.
There are those that would like to paint ALL trading as evil - they do this to try and persuade LTH's, most crucially the large holders, to sit on their hands and not trade with the market. You might think that this is a good thing, but what it does is allow a smaller number of people to control the market dynamics and where the SP settles. Remember that the share price is not an average over what shareholders think the company is worth - it is a reflection only of the weakest shareholders (by definition the ones most willing to sell) which may only be a tiny fraction of a percent of shareholders.
