Generally CCI's investment style is conservatively biased towards grinding out modest, higher probability gains.
However, every portfolio can probably benefit from having a few speculative positions. I've taken a small, speculative position in Westport Innovations. (WPRT).
WPRT is a leader in the field of Natural Gas based engines. In general, I'm thinking the upcoming political season will generate some press about this space, and could be a catalyst to drive a significant increase in the stock price. On the other hand, there are many issues with this (and any) smaller company which makes this a very speculative investment.
My overall rational and timing about taking this position is described in a Seeking Alpha article here.
FYI, since the article was drafted a few days ago, the stock has fallen a few dollars. So now it is obviously even a better buy....lol! More seriously, as discussed in the article, this weeks pull back makes it seem like a good thing that options were used to enter the position, thereby lowering my cost basis.
