Short Term Trading Weekend Lounge: 8-10 Feb, page-49

The way I read it is different to your interpretation. It seems an invitation for an investor with limited market knowledge or time to spend on research of individual stocks, to set aside a fixed amount each month and buy a low cost broad index ETF, irrespective of the share price.  I also think that an index such as the SP500 or Nasdaq 100 is not subject to any fraud or manipulation as the rules for belonging in the group are spelled out and transparent. The only thing to check out however is if the ETF tracking an index does so fairly closely over a long period when the market will have been through many uptrends and downtrends. It has nothing to do with trusting any fund manager; in fact you don't want one.
