I am in favour of stacking up one investment against another when making an investment decision. It prevents tunnel vision investment that can lead to investment disaster. However, because no-one can predict the future with all its twists and turns, it does make sense to have a diversified portfolio across different industries that are not reliant on one theme. For this reason, and knowing you have done your due diligence on both HGH and GNE, if you are happy with both, then I would invest in both. There is no need to try and pick 'the winner' here.
