Tencent Holdings Ltd. shares fell a second day on concern regulators are now turning their sights to Pony Mas business empire, fueling a $62 billion wipe-out that one brokerage says obliterated most of the value of its online finance business.

The stock fell more than 4% in Hong Kong on Monday, following a 4.4.% drop on Friday.

This is significant, as it implies any further declines from here would essentially imply a de-rating of the Tencent multiple.

A move against Tencent would mark a significant escalation in Chinas campaign against the unfettered expansion of its technology giants. Premier Li Keqiang pledged at the National Peoples Congress earlier this month to expand oversight of financial technology, stamp out monopolies, and prevent the unregulated expansion of capital.
