In this edition of The Motley Fool's "Ask a Fool" series, Motley Fool analysts Jason Moser and Brendan Mathews take a question from a reader who asks, "It seems like you set up new funds every so often, to start afresh, and then advertise those that do well long term, ignoring those that do poorly. Can you explain this?”

While we never like to see our stocks down after we recommend them, we know that investing is a marathon, not a sprint. Part of Foolish investing is looking at things with a longer time horizon and it’s important that individual investors recognize this. When looking at companies like InvenSense (NYSE:INVN) and (NASDAQ:AMZN), there will be ups and downs with the stock prices in the near term but both businesses are sound with large market opportunities and excellent prospects. InvenSense is playing into the greater trend of mobile and wearable technology and Amazon is playing into the greater trend of e-commerce which should have investors encouraged and looking out over the next 3-5 years (and even beyond). Jason sees these businesses as great opportunities for investors today.
