Word of the Day: Advancers (Composite 1,368.65, -4.50%)
This is Lin Yi. A big down day, which makes it a good day to explain "Advancers".
Advancers are simply the companies that closed above yesterday's close. Today: 12 up, 25 down, 0 unchanged. When the index moves, a glance at the advancers tells you whether most companies moved together or a few large ones carried it.
First, today's tape: the Composite closed at 1,368.65, -4.50%; 12 names up, 25 down. The biggest gainer was Irisview Medical (GKOX) +6.89%, the biggest decliner Milemark Digital (MRAX) -13.49%.
There was one market-wide headline today: "City regulators open antitrust investigations into several platform companies". Regulators have opened a formal investigation into bundling and data practices at the city's largest platforms. Expectations of fines and business break-ups rise, and smaller merchants gain bargaining power. How the news and the prices relate is something you can check against the numbers above.
Homework: open the market directory, find today's biggest gainer and biggest decliner, and compare their turnover.
A different word tomorrow. If a term stumps you, tell me through site feedback.
