thank you to everyone, page-8

Can I recommend the excellent book "Fooled by Randomness"?

While P+D is undoubtedly routine in the market, it's probably a mistake to assume that every move is the result of one. Market volatility- particularly at the moment- is a fact of life.

Statistical studies have shown that the stock market is far more volatile than you'd expect, that moves that should be "outliers" are far more common than they should be.

That's the game.
