Cost Averaging and Rebalancing In Investing
I think treatment of these topics is a "must" when giving advice to an average Joe investor and these topics would really lend themselves to this video series. For cost averaging consider a simple example of how the strategy works arithmetically and why it's beneficial. This would enlighten a lot or people. For rebalancing talk about maintaining risk levels and the effect of automatically buying low, selling high.
