Fifth Fidelity Trader Leaves Amid Probe

A senior Fidelity Investments trader left the huge mutual fund company this week, the fifth to depart since Boston-based Fidelity recently began reviewing compliance with conflict-of-interest policies covering gifts and trading involving employees’ relatives, a Fidelity spokeswoman said Friday.

The spokeswoman, Anne Crowley, confirmed that David K. Donovan Jr. left Tuesday, but she declined to discuss the circumstances.

Donovan told the Boston Globe that regulators were investigating whether a single trade by his mother was connected to Fidelity’s trading position in stocks. Donovan said his mother’s personal trade “had nothing to do with me.”
