Sector rotation is a term normally applied to stock market trading patterns. In this context, a List of recognized economic sectors sector is understood to mean a group of stocks representing companies in similar lines of business. 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. 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. ref John Murphy, Intermarket Analysis ...?

The benefits of the application of this model include the fact it allows for an outward progression of growth. As with all simple models of such complex phenomena its validity is limited. ref name Smith Smith, P.J. 1962 Calgary A study in urban pattern , Economic Geography , 38 4 , pp.315 329 ref Explanation While accepting the existence of a central business district , Hoyt suggested that zones expand outward from the city center along railroad s, highway s, and other transportation arteries. Using Chicago as an example, an upper class residential sector evolved outward along the desirable Lake Michigan shoreline north of the central business district, while industry extended southward in sectors that followed railroad lines. In developing this model Hoyt observed that it was common for low income households to be near railroad lines, and commercial establishments to be along business thoroughfares. Recognizing that the various transportation routes into an urban area, including railroads, sea ports, and tram lines, represented greater access, Hoyt theorized that cities tended to grow in wedge shaped patterns or sectors emanating from the central business district and centered on major transportation routes.

Orphan date February 2009 Sector slipping is a technique used to deal with defective Disk sector sectors in hard disk drives. Due to the volatility of hard disk s from their moving parts and low tolerances some sectors become defective. Defective sectors can even come on hard disks from the factory so most disks incorporate a bad block recovery system to cope with these issues. Description During a low level Disk formatting format , defect lists are populated which store which sectors are bad. The bad sectors are then mapped and a sector slipping algorithm is utilized. When using sector slipping for bad sectors, disk access time is not largely affected. The drive will just skip over the sectors and takes the same time as it would have to read the sector. Spare sectors are located on the disk to aid in having sectors to slip other sectors down to, allowing for the preservation of sequential ordering of the data. Accuracy of programs reliant on static knowledge of cylinders and block positions will be compromised though. Bad sectors that are found during normal usage of the disk are not capable of having the sector slipping algorithm applied. Instead a linear reallocation, or sector forwarding, is used where a bad sector is replaced with a sector from a spare area. Doing this does affect access times as the disk will need to seek to the spare sector since all further lookups of the bad sector will redirect to the new sector. Example pre Logical Sectors Physical Sectors Pre Low Level Format 0 0 1 1 2 2 3 3 4 4 5 5 6 7 Logical Sectors Physical Sectors Post Low Level Format 0 0 1 1 2 2 3 Bad 3 4 5 Bad 4 6 5 7 pre In this example, physical sectors 3 and 5 were found to be bad. The sectors were then slipped down to allow for the logical sectors to be placed in sequential order on good sectors. Sector 3 was slipped down to 4 and sector 4 was slipped down to 6.
