MM: All waves are sawtoothed???

I have seen a few sinewaves in my life, but I never saw a saw with a sine wave that looked like a sawtooth wave.

I think we have different thinking caps on. Obviously you are writing about stock price sawtooth profiles(velocity, trend reversals, etc.) while I wrote originally about general curve fitting techniques. In that discussion I stated that curve fitting destroys original real data.

In this sense curve fitting may be a "dangerous" technique if it is not applied with good understanding of what it does. Other than that I recognise that curve fitting on stock data may well be very usefull for investment purposes.
