Fidelity posted the market-linked CDs for this month and there is a nice variety this time. There are 6 being offered, whereas it's been down in the 1 or 2 range lately. Here is the link to them:

Like regular CDs, you can buy them in any multiple (of $1000) you like. For any you might consider, you should review the prospectus. Like muni bond prospectuses, they are lengthy, but after reading a couple, you get the feel for what you need to focus on in each. The key point is to understand the composition of the index they are using. Additionally, I think the historical/backtested returns are also important to give an idea of how the index performed through a known period of market performance.
Personally, out of the ones offered this month, I'm buying a few of the two 7 year issues with 200% participation rate (JPM and GS).
Other folks (on ER and other sites) I originally asked for feedback on these a couple years ago immediately gave up when they saw a prospectus with 70+ pages saying it was too complicated for them and wanted nothing to do with them. Others complained about the cut the issuer was getting. My view - it's guaranteed not to lose any principal. Whatever algorithms they're using, if it has a reasonable chance of performing well, then that's good enough for me for the downside protection. In the current environment, where both bonds and CDs are providing no return, the market-linked CDs give the potential for respectable returns with guarantee of no loss (assuming held to maturity).
Anyhow, it falls in to the alternatives category...I just won't post about them on the new/old alternatives thread, as I don't really want to get into a debate with some of the folks who look to pick fights. As I mentioned, for those I have purchased over the past 2 years, they have all performed exceptionally relative to my expectations...to the point where I wish I had purchased more.
