These are some references of texts with reasons why we're still far from being able to make accurate predictions of market fluctuations:
Evidence-Based Technical Analysis, by David Aronson:
http://www.evidencebasedta.com/
The (mis) behavior of Markets, by B. Mandelbrot and R. L. Hudson
http://users.math.yale.edu/~bbm3/web_pdfs/misbehaviorprelude.pdf
Debunking Economics, by Steve Keen
http://www.debunkingeconomics.com/
These are some of the best critiques I've seen on the "science" of economics. I've come to the conclusion that economics is a protoscience, more than a science.
