Forget That Old Adage

Despite the markets remaining near all-time highs, there are many people that are frightened of putting money to work in the S&P 500. It probably comes from an old investing wive’s tale, or meme, as we call them now. I heard it when I spoke to my daughter’s second-grade class on Career Day last week.

The teacher, who had worked for a year as a financial advisor 20 years ago, has been teaching the kids about economics. Well as much as you can teach 8-year olds. When it came to stocks the class choose 4 to follow -- Walt Disney (NYSE:DIS), Apple (NASDAQ:AAPL), Starbucks (NASDAQ:SBUX) and Nike (NYSE:NKE). After a week they were experts (sounds like Twitter (NYSE:TWTR) traders) and ready to express their opinions, including the teacher.

I started my presentation to the children and happened to have a 4-year chart of Walt Disney, moving strongly from the lower left to the upper right, they could easily identify the trend -- Up. And that's when it happened. The teacher jumped in to tell the class that this would not be a good stock to buy because you “buy low and sell high”. The kids all chimed in before she could finish. I immediately corrected her. Actually, buying high and selling higher is a great strategy. We then got into a wrestling match and now I'm looking for a new school for my daughter.
