Losing money investing CPF money

In a ministerial dialogue session, or is it pre election dialogue, a Mr Goh claimed that he lost $350k from his CPF account! This is the strangest thing I have heard so far. I always read glowing reports about CPF members making money from investing in the stock market. And since the stock market always go up in the long run, and the return, as was used to justified in the liberation of the CPF investment scheme then, would always be much more than bank savings. I remember some figures quoted then was something like 25% to 30% in the long run. The scheme started in 1986, revised to include an Enhanced Scheme in 1993. Now it is 2010, average about 20 years since it started, should be long run enough to make money, not 25% but should be at least 10%! Why got people lost so much one? This is really the first time such a big number in losses is reported, and only when a loser admitted it himself. How many more losers out there who have lost their life savings in the hundreds of thousands since the scheme started? Oh, the scheme was revised to downwards in 1997 to protect the CPF members from losing more of their life savings. Talking about smart Alecs.
