Suppose that you write 1000 European call options and try to do the delta hedging by purchasing underlying stocks. The hedge is rebalanced weekly. If the delta of Week 5 is 0.4 and the delta of Week 6 is 0.5, you have to rebalance your position by buying 100 stocks because the delta increases and (0.5 - 0.4) x 1000 = 100.
