Aetna Funds will launch a mutual fund that protects the principal of investors who stay in the fund at least five years — the full amount of the initial investment is guaranteed, less sales charges. Managed by subsidiary Aeltus Investment Management, the Aetna Principal Protection Fund I is a balanced fund with full discretion to swing 100% in either direction or in any combination between bonds and stocks. The initial subscription period is from Aug. 6 to Oct. 5. The guarantee period on the fund is from Oct. 7, 1999, to Oct. 6, 2004.
