+As might be expected, spread strategies involving both long and short options are 
+less easily quantified than outright buys or sells. The calendar spread strategy is one 
+in which the spreader does not want a lot of stock movement - he would prefer the 
+underlying security to remain near the striking price, for that is the area of maximum 
+profit potential. This is reflected by the fact that gamma is negative. Also, for calendar 
+spreads, the passage of time is good, a fact that is reflected by the fact that theta is pos­
+itive. Finally, since an increase in implied volatilities or interest rates would boost 
+prices and widen the spread (creating a profit), vega is positive and rho is negative. 
+A bull spread has positive delta, reflecting the bullish nature of the spread, but 
+it has negative gamma. The reason gamma is negative is that the position becomes 
+less bullish as the underlying security rises, since the profit potential, and hence the 
+bullishness of the position, is limited. For similar reasons, a bear spread has negative 
+delta (reflecting bearishness) and negative gamma (reflecting limited bearishness). 
+Both the bull spread and the bear spread are the same with respect to the other risk 
+measurements: Theta is negative, reflecting the fact that time decay can hurt the 
+spread. Less obvious is the fact that these spreads are hurt by an increase in per­
+ceived volatility; a negative vega tells us this is true, however. 
+These risk measurement tools are important in that they can quite graphically 
+depict the risk and reward characteristics of an option position or option portfolio.
