Higher earnings from the sale of assets in Blackstone's private equity, credit and fund-of-hedge-funds divisions was almost offset by a plunge in proceeds from divestments in its real estate unit.

However, Blackstone's distributable earnings of 57 cents per share was higher than the 49 cents that analysts forecast on average, according to data compiled by Refinitiv.

The New York-based firm reported net income per share on a diluted basis of 45 cents, based on generally accepted accounting principles (GAAP), down 59% from a year ago.

Investors focused on the better-than-expected distributable earnings, which show the cash available for paying dividends, sending shares of Blackstone up 0.7% to $45.59 at midday.

"We view this earnings release as very positive. Blackstone reported (sales of assets) of $10.6 billion (£8.5 billion), which was above our estimate of $8.9 billion and higher quarter-over-quarter," Credit Suisse analysts wrote in a research note.

Blackstone said its assets under management rose to a record $545.5 billion in the three months through June, from $511.8 billion in the prior quarter.

"We reported capital inflows of just over $100 billion in both 2017 and 2018, and will achieve significantly more in 2019. This ultimately drives growth in earnings," Blackstone President Jonathan Gray told analysts on a conference call.

Blackstone does not plan to give voting rights to outside shareholders in order to be allowed to join the Russell 1000 Index and gain more exposure to investors, Gray added.

The firm said it would pay a second-quarter distribution of 48 cents per share.

Blackstone said the value of its private equity portfolio appreciated by 0.7%, compared to a 3.8% rise in the benchmark S&P 500 stock index <.SXP>. Opportunistic funds and core real estate funds appreciated 4.4% and 0.8% in the quarter, respectively.

Stock market swings impact private equity firms because they often have large public market holdings in investments that they are in the process of exiting. Public markets are also used as a measuring stick when valuing private investments.

Chief Executive Stephen Schwarzman said the trade war between the United States and China had limited impact on Blackstone because it does not own many businesses in the global supply chain, whether they are retailers or big exporters.

This was Blackstone's first earnings report since officially converting from a partnership to a corporation on July 1, a move designed to boost its share price.

Since making the announcement in April, Blackstone's stock has jumped by around 25%, outperforming the broader market.
