A trader is short 10,000 European call options on a non-dividend-paying stock. Each option has a delta of 0.55. To make the position delta-neutral, the trader should:

The trader should buy 5,500 shares. The short calls have a combined delta of -5,500 (0.55 times 10,000, with a negative sign for being short), so holding 5,500 long shares brings the net delta of the portfolio to zero.

Explanation

A short call position has delta of -0.55 x 10,000 = -5,500 shares. Buying 5,500 shares adds +5,500 and offsets it to zero. Selling shares would double the negative exposure; 10,000 shares ignores the delta scaling.
