A.	The investment time horizon over which a stock is held is called the "holding period." Compute the "Big 4" for 1-year and 30-year holding period returns for the Dow:
	Statistic	One Year Holding Periods	30-year Holding Periods
	Average	12.0%	?	(This is not the compounded average return, but siimply the arithmetic average return, which is always higher than the compounded return.)
	Max	54.0%	?
	Min	-43.4%	?
	St Dev	20%	?
	95% percentile	39%	?
	5% percentile	-23%	?
B.	Compare one-year vs. 30-year holding periods. Which has greater variability in terms of average return?
C.	What do these results imply for young investors?
