Occasional portfolio rebalancing is necessary unless you are only invested in an automatic glide path fund. I just contribute funds to the deficient allocation category. If it requires a much higher amount than the funds available, utilizing leverage can get me to a balanced portfolio quicker.

+ By utilizing derivatives when rebalancing, I can turn a buy into a sell and vice versa. The notional values of long or short derivatives can simulate a reduction or an increase in that asset class. As an example, let's say I need to sell $4000 of large cap to rebalance. Instead of selling that stock, I can buy a put, which will have a negative notional value. Say SPYM is trading at 80. A .50 delta PUT 200 days out might cost $400. By buying that, I've created a notional value of:

+ ```math
+ \text{Notional Value} = 80 \times 100 \times .50 \times -1 = -4000
+ ```
