\begin{abstract} | |
We will pretend that HAM1 is real and investable with a marketing team that can raise billions of dollars. In reality, HAM1 is imaginary. HAM1 uses proprietary techniques built from decades of experience and centuries of historical data to identify high return opportunities. | |

Unfortunately, the Return section is generally the focus of the sales pitch and also is often the biggest concern for the prospect. Although it easiest to sell on return in the short-term, long-term success requires much more focus on the graphs presented in the Overview and Risk sections. | |
