Here, we see that market timing can work, when doing it based on supply and demand issues of said securities. This, all things said and told, is similar to the idea that buying newly spun off securities when the market is flooded with shares can do well for investors.
Obviously, timing should only be used in price to value issues, but, these behavioral movements (based on something as simple as when people get paid) are certainly interesting to consider. Additionally, there is always the chance that terrible news could come out, and tank your investment, when exposed to a limited time's worth of holding. Whereas, these issues are more able to iron out over the long haul.
