This article is solely about positive feedback loops (even though the author never says "positive.") If positive feedback loops were the whole story every stock that rose a little would take off like a rocket. Clearly that doesn't happen, and it's because there are also negative feedback loops, like noticing that a stock is overvalued and refusing to buy it until the price comes down.

What makes the future difficult to predict is that negative feedback loops and positive feedback loops are often fighting each other and you never know early on which will ultimately dominate.
