  The Bohmian quantum approach is implemented to analyze the financial markets.
In this approach, there is a wave function that leads to a quantum potential.
This potential can explain the relevance and entanglements of the agent's
behaviors with the past. The light is shed by considering the relevance of the
market conditions with the previous market conditions enabling the conversion
of the local concepts to the global ones. We have shown that there are two
potential limits for each market. In essence, these potential limits act as a
boundary which limits the return values inside it. By estimating the difference
between these two limits in each market, it is found that the quantum
potentials of the return time series in different time scales, possess a
scaling behavior. The slopes of the scaling behaviors in mature, emerging and
commodity markets show different patterns. The emerge market having a slope
greater than 0.5, has a higher value compared to the corresponding values for
the mature and commodity markets which is less than 0.5. The cut-off observed
in the curve of the commodity market indicates the threshold for the efficiency
of the global effects. While before the cut-off, local effects in the market
are dominant, as in the case of the mature markets. The findings could prove
adequate for investors in different markets to invest in different time
horizons.
