The line graph above plots the daily fluctuation of the stock market index for the 19 days from March 1 to March 19.
On March 1, the stock market index sat at approximately 1.05. From there it climbed to roughly 1.25 on March 4, plunged for a day, and then by March 7 nearly regained its previous peak. The index then declined for two days. It rebounded slightly to above 1.1 on March 10, but declined again the following day. From March 12 to 14 the index increased again, reaching just above 1.2 before it plunged drastically on March 15. March 16 saw the greatest single-day increase in the stock index, up to 1.3. The final three days first saw a plunge in the index, then a slight continued decline back to the same level as the first day.
Although the stock market index peaked on March 16, from start to finish for this period there was no increase in the index.
