I live in Dallas. This guy bombards the airwaves every week with his program on numerous am radio stations. His show features goofy sound effects, and he pushes seminars offering free "oatmeal chocolate chunk" cookies. I occasionally enjoy listening to him, just so I can shake my head that people would believe that he has some sort of system that can successfully determine when to "get in" and "get out" of the market. On each program that I have heard, he has touted that his clients were out of the equity markets from late 2007 to June of 2009 - but I haven't usually heard him tout that he also pulled his clients out of the market in 2010 and 2011 during periods that meant his clients missed significant runups in stock markets (and then he had them buy back in at higher prices when markets were up). From information on his website, it appears he advised clients to sell on June 8, 2010 (S&P was at 1,062) and then advised them to buy back in on October 6, 2010 (S&P was at 1159). In 2011, he advised clients to sell on August 5 (S&P at 1199) and then advised clients to buy back in on January 19, 2012 (S&P was at 1314).
In my opinion, if he could predict the future with any degree of accuracy on a consistent basis, he'd be a billionaire investing his own money, rather than bothering to make a living getting fees from middle class retirees. According to the brochure for his firm filed with the SEC, they generally charge a fee of 1% of assets under management - I personally wouldn't have enjoyed the "privilege" in 2010 and 2011 of paying 1% for having him sit me in cash or fixed and miss the vast majority of the 28% run up in S&P from his 1062 sell point to today's 1362 close.
If you can redirect your brother in law to Assetbuilder (or to numerous other people in the Dallas area who offer low-cost, sound advice that doesn't rely on active management or market timing), I believe you will be doing him a service.
