Online grocer Ocado, Swedish property firm Fastighets AB Balder, and French train maker Alstom, were among the three most shorted stocks in June, but all three saw positive share price performance over the month, according to a report by Reuters.

The report cites data and tech firm Hazeltree's Shortside Crowdedness Report, which collects stock borrowing data globally from about 700 asset management funds in large and mid-cap stocks across Europe, the Middle East and Africa, as revealing the short positions in the three companies.

Global hedge funds including Man Group and AQR Capital Management were reportedly among those short-sellers facing potential losses on their bets against Ocado after the online grocer's stock price surged on 22 June on the back of a news from research group Breakout Point of a potential takeover bid from Amazon. The online retail giant denied the speculation, but Ocado's stock still jumped 62% over the month.

Despite soaring interest rates and falling property values in Sweden meanwhile, domestic real estate firm Fastighets AB Balder saw its stock price rise about 7% over the course of June. And French train manufacturer Alstom also saw its shares rise 5% during the month.
