A client owns 200 shares of ABC stock at $45 per share. The company announces a 1-for-4 reverse stock split. After the split, what will be the client's new share count and cost basis per share?

  1. A50 shares at $45 per share
  2. B800 shares at $11.25 per share
  3. C800 shares at $180 per share
  4. D50 shares at $180 per share
Show answer & explanation

Correct answer: D. 50 shares at $180 per share

In a reverse stock split, the number of shares decreases, and the price per share increases proportionally, while the total value of the investment remains the same. For a 1-for-4 split, the investor will have 1/4 of their original shares, and the cost basis per share will be 4 times the original cost basis.

Why the other options are wrong

  • A. While the share count is correct, the cost basis per share should increase, not stay the same.
  • B. This represents a forward stock split (4-for-1) rather than a reverse split.
  • C. This incorrect combination reflects both an increased share count and increased price, which is not how a reverse split works.

Reverse Stock Split

A corporate action where a company reduces the total number of its outstanding shares by consolidating them into fewer, proportionally more valuable shares. The total market value of an investor's holding remains the same.

  • Decreases the number of shares.
  • Increases the price per share.
  • Total value of holding remains unchanged.
  • Often used to increase stock price to meet listing requirements or improve perception.

Memory trick: Reverse Split: Fewer shares, higher price, same total pie!
