The proletariat will use its political supremacy to wrest, by degree, all capital from the bourgeoisie, to centralise all
instruments of production in the
hands of the State,
i.e., of the proletariat organised as the ruling class; and to increase the total productive forces as rapidly as possible.
If, on the other
hand, the spread between a future traded on an underlying asset and the spot price of the underlying asset was set to widen, possibly due to a rise in short - term interest rates, then an investor would be advised to sell the spread (
i.e. a calendar spread where the trader sells the near - dated
instrument and simultaneously buys the future on the underlying).
