Sorry, something has gone wrong. Best Answer: The Enhanced Fujita Scale, or EF Scale, is the scale for rating the strength of tornadoes in the United States estimated via the damage they cause.
DEFINITION of 'Basis Trading'. An arbitrage trading strategy that aims to profit from perceived mispricing of similar securities.
If the basis is more negative or less positive than usual, it is considered weaker than the historical norm. If it is less negative or more positive, then, it is said to be stronger. Say that September cash corn is trading at 228 cents/bushel and December futures corn is trading at 248 cents/bushel. In market parlance: The basis is 20 under December. The basis indicates current local demand. A strong basis means the market wants the grain sooner rather than later. A weak basis suggests that the market doesn't want grain now, although demand may grow over a matter of months. Strong basis trends toward a less negative and more positive number.
