Zeal does believe in commodity bull market and they research to provide recommendations of how you can benefit from the best of stocks during that bull market. Believing in commodity bull is not a bad thing, it is personal belief and if you don’t agree with the core thinking of zeal (equties are over priced, commodities are in bull run that will continue till 2013) then you shouldn;t even go look at zeal.
I personally don’t ascribe to newsletters that subscribe to a commodity or equity or one way or other mentality. Also, based on my personality, I like trading as I don’t have the patience for long term investing so I normally try to capture short term trends. You need to have a lot more patience and risk tolerance to be long term investor as it means believing in long term you will come out doing better than most. But this also depends how early you need your investment back and what are you investing it for. e.g. I don’t trade the money I am setting aside for downpayment of a house in 3 years time frame as 3 years is too short.
