I learned the hard way that Hargreaves Lansdown's recommendations have more to do with marketing than the interests of the client when I bought their package of recommended funds one ISA season, only to see that they had fallen by over 60% by next valuation, and continued to fall thereafter. From that I learned that I must do my own research, ignore most of the bumpf churned out by HL, and trust my own judgement. The Wealth 150 is a very curious list, and most of my best performers have not been on it – unlike most of my worst performers! Actually, I should have been warned off years earlier when Peter Hargreaves himself warned me off buying Fidelity Special Situations just as Anthony Bolton began his stellar run.. (He recommended Prolific Special Situations instead).
There are other issues with HL. Their charges for buying / selling / keeping ITs and other shares in an ISA are high (Barclays is much cheaper), and buying funds I have often found that the buying price is higher than that listed, so it seems that initial charges are not always fully rebated even where that is promised.
