Jake's View | Smell a rat? Let the market deal with it
Efforts by the CSRC to stop 'rat trading' across the border should be applauded, but the regulator may not know the extent of the problem

Probe into rat trading spurs fund managers to quit
I have never been quite certain what they mean across the border by "rat trading". It seems on this occasion that the offence is defined as overly active trading by stockbrokers in discretionary accounts managed on behalf of relatives.
I have also heard it defined there as collusion with other brokers to split the difference in profits from executing client trades at bad prices.
That's what comes of using meaningless pejorative terms favoured by regulators. You know they refer to badness in the market but you never know what particular badness.
To me rat trading has never meant more than good old-fashioned front running. Jump in first when the client gives you a big buy order, wait until his buying has pushed the price up and then sell. Best do it through a blanket account at a big New York bank to be safe.
