PetroChina Co., China's largest oil producer, jumped 44 cents, or 2.4 percent, to HK$19.14. A 74 percent gain in its shares this year helped PetroChina to this week overtake General Electric Co. as the world's second-largest company by market value.
i bought a 210 November put to hedge out some other longs I have (not chinese)... but yes, playing with fire. I wouldn't dare outright short it.. Not in this market.
If Chinese govt came out and said HK/Shanghai arb is a no go and/or Shanghai actually had a long overdue correction, this would shave 50 pts in a second.
