I have 4 investments:

	Weight	Expected Return	Standard Deviation
Small-Cap Growth Stock	25%	10%	9.37%
Large-Cap Value Stock	35%	5%	14.52%
Foreign Stock	10%	5%	10.59%
Treasury Bond	30%	5%	6.22%

The correlation between:

Small-Cap & Large Cap	0.93
Small-Cap & Foreign	0.93
Small-Cap & Treasury Bond	- 0.96
Large-Cap & Foreign	1
Large-Cap & Treasury Bond	- 0.99
Foreign & Treasury Bond	- 0.99

How to rebalance this allocation?

Assume I have $100,000, I want to invest for long term. So, I created an aggressive portfolio with four assets - small cap (25%), large cap (35%), foreign stock (10%), and treasury bond (30%).

After calculating the Expected Return and Stadard deviation, the large cap has the highest risk.

So, should I change my asset allocation such as the percentage of each investment or invest one more class (cash or real eastate) or shift the time horizon?
