If the board of directors approves a two-for-one stock split, how many shares will an investor own after the split if they initially had 150 shares?

When a company implements a two-for-one stock split, it effectively doubles the number of shares outstanding while halving the value of each individual share. This action does not change the overall value of the investor's holdings; it merely increases the number of shares while decreasing the price per share proportionately.

If an investor initially owns 150 shares, after a two-for-one stock split, they will receive an additional share for every share they already own. Therefore, the calculation would be as follows:

150 shares x 2 = 300 shares.

Thus, after the stock split, the investor will own a total of 300 shares. This reflects the nature of a stock split where existing shareholders have their shares multiplied by the split ratio, leading to increased share count while the total value of their investment remains unchanged.
