Trading Curb
A trading curb (also known as a circuit breaker in Wall Street parlance) is a financial regulatory instrument that is in place to prevent stock market crashes from occurring, and is implemented by the relevant stock exchange organization. Since their inception, circuit breakers have been modified to prevent both speculative gains and dramatic losses within a small time frame. When triggered, circuit breakers either stop trading for a small amount of time or close trading early in order to allow accurate information to flow among market makers and for institutional traders to assess their positions and make rational decisions.

Positive Feedback
Positive feedback (exacerbating feedback, self-reinforcing feedback) is a process that occurs in a feedback loop where the outcome of a process reinforces the inciting process to build momentum. As such, these forces can exacerbate the effects of a small disturbance. That is, the effects of a perturbation on a system include an increase in the magnitude of the perturbation. That is, ''A produces more of B which in turn produces more of A''.Keesing, R.M. (1981). Cultural anthropology: A contemporary perspective (2nd ed.) p.149. Sydney: Holt, Rinehard & Winston, Inc. In contrast, a system in which the results of a change act to reduce or counteract it has negative feedback. Both concepts play an important role in science and engineering, including biology, chemistry, and cybernetics. Mathematically, positive feedback is defined as a positive loop gain around a closed loop of cause and effect. That is, positive feedback is Phase (waves), in phase with the input, in the sense that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Program Trading
Program trading is a type of trading in Security (finance), securities, usually consisting of baskets of fifteen stocks or more that are executed by a computer program simultaneously based on predetermined conditions. Program trading is often used by hedge funds and other institutional investors pursuing index arbitrage or other arbitrage strategies. There are essentially two reasons to use program trading, either because of the desire to trade many stocks simultaneously (for example, when a mutual fund receives an influx of money it will use that money to increase its holdings in the multiple stocks which the fund is based on), or alternatively to arbitrage temporary price discrepancies between related financial instruments, such as between an index and its constituent parts. According to the New York Stock Exchange, in 2006 program trading accounts for about 30% and as high as 46.4% of the trading volume on that exchange every day.

Black Monday (2020)
On 20 February 2020, stock markets across the world suddenly crashed after growing instability due to the COVID-19 pandemic. The crash ended on 7 April 2020. Beginning on 13 May 2019, the yield curve on U.S. Treasury securities inverted, and remained so until 11 October 2019, when it reverted to normal. Through 2019, while some economists (including Campbell Harvey and former New York Federal Reserve economist Arturo Estrella), argued that a recession in the following year was likely, other economists (including the managing director of Wells Fargo Securities Michael Schumacher and San Francisco Federal Reserve President Mary C. Daly) argued that inverted yield curves may no longer be a reliable recession predictor. The yield curve on U.S. Treasuries would not invert again until 30 January 2020 when the World Health Organization declared the COVID-19 outbreak to be a Public Health Emergency of International Concern, four weeks after local health commission officials ...
