The main problem with investing small sums is that trading fees can take up a larger percentage of the total. For example, if you invest $100 and are charged a flat $5 fee, you retain $95 in your investment. If you invested $5, you retain $0. (Fees can switch to a proportional basis for larger sums invested, but they are often a flat rate at the lower end.)

There is common advice to rebalance your portfolio. This is done to keep the balance between the sectors. If an investor wants to be 40% large company stocks, ...
The point of rebalancing is to decrease the allocation to securities that have performed well (sell high) and increase those that have not performed as well "buy low". If you add funds to the account often, you might be able to maintain your target allocation just by choosing the percentage of each that you buy with the new funds - but if you are ...
