Answer:
600 shares
Step-by-step explanation:
If a 3-for-2 stock split will take place, for every 2 stocks that an investor has, he will receive three stocks. So this specific investors who owns 400 stocks will receive:
(400 / 2) x 3 = 200 x 3 = 600 stocks.
After the 3-for-2 stock split, the company will have 50% more stocks outstanding and the price of each stock should be reduced by one third. So the investor shouldn't earn any profit from this split since the market value of the investment should remain about the same (stock prices change daily whether the split takes place or not).
