I said I can’t do that. They are all so cut-and-dried, such simple buys and sells…Once anyone realizes they can do this themselves why would they pay me?

He replied: “You’re not selling signals, dad, you would be selling the reassurance the signals work. That is worth a lot, a lot, lot more than the signals themselves?

I had to laugh since I’m only do this for fun, and, needless to say, the benefit of all mankind.

“Sometimes they don’t work the way they are expected to work,” I said. And he reminded me I’ve always said “when the McClellans are doing what they are supposed to do, they are great, but when they are not working the way they’re supposed to, they are even greater.”

Even greater when they don’t work? Indeed.

For instance, when they are not working it is often a sign that something bigger in the market is going on — like an…
