Hedge funds increased their long wagers on US real estate investment stocks last week for the sixth connective week, backing a rebound in both the country's commercial and industrial property sectors, according to a report by Reuters.

The report cites a note from Goldman Sachs as highlighting that the real estate was the net most bought stock sector tracked by the company's prime brokerage division, which serves hedge fund clients.

Real estate investment trusts (REITs) with diversified portfolios attracted much of the hedge fund buying, according to the note, as well as REITs that focus on office space and specialised real estate holdings.

Hedge funds remain short on retail, healthcare, and hotel and resort-focus REITs, according to Goldman.
