For example, an investor or trader may describe the current market movements as favoring basic material stocks over semiconductor stocks by calling the environment a sector rotation from semiconductors to basic materials.
Sector Rotation Models exist primarily to help investors identify and participate in new trending sectors of the stock market. A sector rotation investment strategy is not a passive investment strategy like indexing, and requires periodic review and adjustment of sector holdings. Tactical asset allocation and sector rotation strategies require patience and discipline, but have the potential to outperform passive indexing investment strategies.
An example of a sector rotation theory would be:
This includes stocks like consumer cyclicals and financial companies. These would do well when the market is at bottom.
This includes stocks like technology and telecommunication. These should go up more than the overall market in the main part of a bull market.
This includes stocks like energy companies. These would do well when the market is at top.
This includes consumer staples. These should do least bad in a bear market.
Note that this is sectors relative to the overall market. It is expected that, during a bear market, all stocks will go down some.
The primary driver of sector rotation is the variability of currency values (inflationary, disinflationary, or deflationary) and interest rates. As the economy expands, demand for raw materials creates inflationary pressures, which in turn prompt higher interest rates, which increase the value of the currency, which reduces the competitiveness of a country's exports as the currency causes them to cost more to other countries. This final stage causes the economy to contract, reducing demand for raw materials, which creates deflationary pressures, which in turn prompt lower interest rates, which decrease the value of the currency, which increases the competitiveness of a country's exports—creating a new market cycle. The relative strength of commodities, bonds, currencies, and stocks shift in this changing monetary climate in a somewhat predictable manner.
