My opinion is based on over 20 year's experience in Financial Services as an Independent Financial Adviser and though now retired from Financial Services I continue to take a keen interest.
Fidelity as a group have a good reputation among most Advisers and over the years rovided my clients with some outstanding results on their investments.
Their Europen fund up to 10 years ago was a classic example of how Long-Term investing can be so important.
The problems within the group like many other investment houses is when Fund Managers leave or retire. Long term sucess like Footbal management often comes about through experience and stability. Chopping and changing managers rarely proves beneficial.
Fidelity score highly through having company researchers accross the Globe. This enble them to stock pick with some confidence from great knowledge of the chosen investment areas.
No investment house is without problems and ups and downs. Fidelity have at times fallen out with Advisers over their attitude and can sometimes appear aloof to small Independent Adviser firms.
Their service is generally very good and for fund management over the longer term (IE over 5 years) thay have a good track record.
In my experience many clients are coerced into investments with too short a view. Fidelity fund should be regarded as Long Term investments and clients must accept the ups and downs that will invariable go with the nature of the beast.
