The 12 month moving average has been a pretty good tool for spotting bull and bear markets. However there are two types of bulls, cyclical and secular.
The first two charts appear to be cyclical bulls. The S&P is most definitely a cyclical bull within a secular bear. The CRB is debatable at this point. Generally speaking the only asset class that can even be vaguely considered to have improving fundamentals would be commodities. However the demand side of the equation is now impaired for most commodities.
