I am a very long term investment. I had bought this share $ResMed(RMD)$ since 2008 till now. However, I have sold and bought along the years. If I have hold on all the shares that I had bought since 2008. I could easily earn more than 1million now. Therefore, my thought is like Warren Buffet, hold on to the shares if you like the company business model. You think the company have a great potential of growthing in the market, you should hold on for long term. It will be able to give you the return x2/×3/×4/×5.....×10.
