A Market Maker exists to “create a market” for specific company securities by being willing to buy and sell those securities at a specified displayed price and quantity to broker-dealer firms that are members of the exchange.

These firms help keep financial markets liquid by making it easier for investors to buy and sell securities–they ensure that there is always someone to buy and sell to at the time of trade.

The winter solstice, also called the hibernal solstice, occurs when either of Earth’s poles reaches its maximum tilt away from the Sun. This happens twice yearly, once in each hemisphere (North and South). For that hemisphere, the winter solstice is the day with the shortest period of daylight and longest night of the year, and when the Sun is at its lowest daily maximum elevation in the sky. Each polar region experiences continuous darkness or twilight around its winter solstice.

US stocks bounced back Friday as investors digested key inflation data that showed a deceleration in price increases during the month of November.

The tech-heavy NASDAQ Composite (^IXIC) gained 1%. The Dow Jones Industrial Average (^DJI) added 1.2%, while the S&P 500 (^GSPC) rose 1.1%.

But the rebound wasn’t enough to overcome losses earlier in the week. All three major gauges finished the week lower. The NASDAQ gave up 1.8% while the Dow and the S&P both shed around 2%.
