The Wall Street Journal this morning is reporting that the Securities Exchange Commission in the USA is investigating the circumstances surrounding Ansys's takeover of Ansoft — as well as a dozen other deals involving drug makers, consumer stores, and so on.
It's not Ansys itself who is being investigated, but deal advisers and traders who may have shared confidential information to profit from the takeovers.
The investigations are part of an effort to better understand how people meet and communicate with one another — and swap information — among banks and Wall Street trading floors.
People who have seen the subpoenas say hedge-fund executives are being asked to hand over appointment books and business-contact lists, in addition to phone and email records.
