Word of the Day: Intraday range (Composite 1,185.48, -0.56%)
This is Lin Yi. A lot of news today, which makes it a good day to explain "Intraday range".
There was one market-wide headline today: "The city tightens mortgage and development-loan rules". The Authority has raised down-payment requirements and tightened development loan quotas. Transaction expectations move lower, and growth in building materials demand and bank mortgages slows. How the news and the prices relate is something you can check against the numbers above.
The intraday range is the day's high minus the day's low, divided by the prior close. The index travelled between 1,185.48 and 1,220.10 today, a range of 2.90%. Among single stocks the widest was Basinrock Resources (PRMX) at 15.93%. A close tells you where the day ended; the range tells you how far it wandered on the way.
First, today's tape: the Composite closed at 1,185.48, -0.56%; 20 names up, 17 down. The biggest gainer was Milemark Digital (MRAX) +9.07%, the biggest decliner Fahrenheit Beverages (CELX) -14.36%.
Homework: pick a company that barely moved today, look up its sector's average change, and think about why it didn't follow.
Class dismissed. See you tomorrow.
