It is becoming hard to find a good company at a fair price at this stage of the bull market. I have been fortunate enough to discover such an opportunity in CME group.
Just like Visa or MasterCard, CME is using their platform to offer a service and collect a fee on the volume of transactions done on it. So there is no credit risk for them. I really love this type of business because it offers a good long term opportunity to accumulate capital gains. This is also a dividend play, on top of which it gives a yearly one time dividend sort of a bonus depending on how well the platform performs.
If you are looking for a fairly valued platform I strongly suggest you visit the website above
