Sure that all sounds nice in theory. Reality is different though. I don't know how many "bagholders" I have seen in the last 15 years who all pretended to be long term investors. Heck maybe I just followed the wrong stocks for 15 years.
I think we just look at it from different angles. Think about it. What do I have from your 4.5% ROI every week if the stock is at a 2 or 3 year low now? That's all that counts in my book. Nothing else. All else is just theoretical noise.
