`Volatility surrounding his trades occurs not because of index arbitrage, but because his is a large addition or subtraction to a widget market with finite liquidity.`
Arg1:	Volatility surrounding his trades
REL:	occurs
Argm-CAU:	not because of index arbitrage, but because his is a large addition or subtraction to a widget market with finite liquidity.

The corresponding sense of 'happen' shows an Arg2 'benefactive', with prepositions 'with' and 'for'. I didn't see any in the financial subcorpus, but they might occur. Maybe.
