Markets are efficient, but prices are not.  Prices move wherever the
markets lead them to in response to supply and demand.  Prices tend to
equalize supply and demand, in order to maintain the markets
efficiency, ie., a free market's.  But it does take time to maintain a
markets efficiency.  During this time, a seemingly random movement of
the prices is a tug of war between bulls and bears responding to
supply and demand.

A market that is not free is not efficient because the prices are
artificially controlled by a state monopoly (with no regard to profits
and losses except the alledged public good) and not by the competition
created by free market.  In a fully free ("laisez-faire") market,
monopolies cannot exist but for a brief duration in time before other
producers enter the market and depress prices...
