A naif with great instincts.

I need to understand the costs of buying and selling stock. As well as the tax implications.

I turned to my wife on Sunday and said, "I wish I had sold everything last week."

I know when I bought Barnes and Noble stock, that there was a cost involved. When it reached a peak of 15% higher, I thought I ought to sell, but I wasn't sure how much it would cost.

As of today, the stock is 10% lower than when I bought it, for a swing of 25%.

It was a small amount I invested, just to experiment. But obviously, I need to do more research, because what stopped me from selling was fear of costs, and I'm not sure about that.

I'm a naif.

A naif with great instincts, I think, which come from watching the collectibles market rise and fall for a few decades. It appears to me that there are many similar characteristics in customer behavior.
