The ProShares UltraSh FTSE/Xinhua China 25 (NYSE:FXP), which correspond to twice the inverse of the daily performance of the FTSE/Xinhua China 25 index, could be poised for a big move on Monday.

Asian stock markets opened sharply lower Monday, dragged down by triple digit losses on Wall Street Friday and continued fears that Chinese growth is slowing.

Investors moved into safe haven U.S. and Japanese government bonds, sending the Nikkei 225 Stock Average down 2% to 10255. Hong Kong's Hang Seng Index was down 2.4% to 19667.

Markets were "predictably" weak after the falls in U.S. and European equities, said Jamie Spiteri, head of trading at Shaw Stockbroking in Sydney.
