Technical analysis gets into trouble when the art from
migrates from the study of stocks, commodities and currencies and into the
price forecasting of the major stock indices such as the S&P/TSX Composite,
the S&P500 or the NASDAQ Composite.
Not a day passes when some technician looks at a
major stock index and sees a head & shoulders top, support or resistance at
so-and-so level, a double top or a double bottom. Pile on seasonality, moving averages, price momentum,
historical comparisons and you get an index forecast that may be correct –
about one-half the time.
The problem is that a major stock index is a basket of diverse sectors (like
financial, energy or consumer) that – for the most part – do not advance and decline
at the same time. Remember the great dot-com bust of 2000-2002? It was a
non-event if you owned financial and energy stocks. Our own TSX Composite is
dominated by three sectors – financial, energy and materials. If you add in the
industrials we have about 76% if the index
covered.
