They may be basing their study on the German government finishing selling all of its seized Bitcoin, as well as liquidating Mt.Gox's creditors, although I know that they have not finished yet and the distributions will continue during the following months.
But I do not think that a period of one month is sufficient for Bitcoin to rise to the desired extent. There may be a recovery in the cryptocurrency market in August, but I do not expect that it will be as much as we hope.
Personally, according to my expectations, we will not see a significant increase before the end of the year and the beginning of the new year.
