  Applications of Quantum Tunneling effect have long gone beyond the
traditional physical meaning. Initially created by Gamow to explain
{\alpha}-decay of nuclear particles, along the time, quantum tunneling found
fertile domain of research in chemistry and recently in biology, where the new
discipline of Quantum Biology emerges. The present paper extends the
applicability of quantum tunneling to financial markets. In a recent paper [1]
a time-independent equation for pricing the options having the underlying stock
in a range bound markets is found. The equation is identical with a
time-independent Schrodinger equation but incorporates elements of finance. The
financial time-independent equation for option pricing is solved to explain a
particular explosive violent movement of stock price in range bound markets.
The aforementioned particular stock price movement is assimilated with a
quantum tunneling effect. The probability of stock price to quantum tunneling
out of the bounded region, known as transmission coefficient, is deduced.
Quantum aspects of tunneling effect in financial markets are discussed. Recent
evidences of price quantum tunneling in stock market are also shown.
