Maybe THIS MF ARTICLE can shed some light to the reason behind the lack of share price rebound.
Specifically, Where a creditor accepts warrants (shares that will vest at a future date) the maximum they can obtain is up to 15% of any uplift in the market value of Slater & Gordon for 30 days from the effective date of the amendment (presumably) at April 30 2016.
I don't know how much of this is true, see as detail of the warrant wasn't raised, but if this is true, then I can see why it's in investors' interest to keep SGH share price as low as possible for the month.
