Presidents are often measured by what they achieve during their first 100 days in office. Schools have parties for students on the 100th day of the school year. Newly appointed business executives are often expected to affect substantial change, if not realize greater shareholder value, within their first 100 days.

Around here at Motley Fool CAPS, we keep an eye on the 100-day mark, too. Some of our best investors -- we call them All-Stars -- have achieved top player ratings after garnering a score of 100 in their first 100 days on CAPS. Analysis has shown that the top-rated stocks have had the best performance over our first year of collecting data, so might we assume that when the best players rate the best stocks, there is a correlation as well?

One of our highest-rated CAPS investors is RonChapmanJr, who sports a nearly perfect 99.97 player rating. A player since December 2006, RonChapmanJr currently has 194 active picks on CAPS out of more than 530 stock picks made.

Lost at sea?
Even when you have soaring demand for your services, your profits will suffer when providing every new item costs increasingly more. That's the situation that shipping and logistics company Navios Maritime finds itself in. Revenue grew more than 230% to $338 million as it enjoyed higher vessel rates and increased fleet utilization as a result of robust worldwide demand for commodities. Yet Navios suffered from an even greater increase in time charter, voyage, and port terminal expenses. Those costs rose nearly 400%.

Investors remain bullish, though, on the dry bulk shipper. Many believe that continuing demand for goods around the globe will offset any short-term issues. CAPS player onemanjamboree finds Navios to be undervalued, as well as a play on the commodities market:

Dry Bulk shipper that is most undervalued compared to its competitors. Shippers are due for a big rebound this year and Navios Maritime is positioned well for growth. Fantastic opportunity to be bullish on the commodities market with a shipper poised for growth.
