d) At the New York Stock Exchange a certain online gaming stock had an initial public offering (IPO) price of 10 USD per share and is traded 24 hours a day. Sketch the graph of the share price over a 2-year period for each of the following cases:
(i) The price increases steadily to 50 USD a share over the first 18 months and then decreases steadily to 25 USD per share over the next 6 months.
(ii) The price takes just 2 months to rise at a constant rate to 15 USD a share and then slowly drops to 8 USD over the next 9 months before steadily rising to 20 USD.
(iii) The price steadily rises to 60 USD a share during the first year, at which time an accounting scandal is uncovered. The price gaps down to 25 USD a share and then steadily decreases to 5 USD over the next 3 months before rising at a constant rate to close at 12 USD at the end of the 2-year period.
