It started in September, when share prices on the New York Stock Exchange (NYSE) collapsed, and ended in mid-November. The pivotal role of the 1920s' high-flying bull market and the subsequent catastrophic collapse of the NYSE in late 1929 is often highlighted in explanations of the causes of the worldwide Great Depression.

In statistics, economics, and finance, an index is a statistical measure of change in a representative group of individual data points. These data may be derived from any number of sources, including company performance, prices, productivity, and employment. Economic indices track economic health from different perspectives. Examples include the consumer price index, which measures changes in retail prices paid by consumers, and the cost-of-living index (COLI), which measures the relative cost of living over time.

Market sentiment, also known as investor attention, is the general prevailing attitude of investors as to anticipated price development in a market. This attitude is the accumulation of a variety of fundamental and technical factors, including price history, economic reports, seasonal factors, and national and world events. If investors expect upward price movement in the stock market, the sentiment is said to be bullish. On the contrary, if the market sentiment is bearish, most investors expect downward price movement. Market participants who maintain a static sentiment, regardless of market conditions, are described as permabulls and permabears respectively. Market sentiment is usually considered as a contrarian indicator: what most people expect is a good thing to bet against. Market sentiment is used because it is believed to be a good predictor of market moves, especially when it is more extreme. Very bearish sentiment is usually followed by the market going up more than normal, and vice versa. A bull market refers to a sustained period of either realized or expected price rises, whereas a bear market is used to describe when an index or stock has fallen 20% or more from a recent high for a sustained length of time.
The "Fed model", or "Fed Stock Valuation Model" (FSVM), is a disputed theory of equity valuation that compares the stock market's forward earnings yield to the nominal yield on long-term government bonds, and that the stock market – as a whole – is fairly valued, when the one-year forward-looking I/B/E/S earnings yield equals the 10-year nominal Treasury yield; deviations suggest over-or-under valuation.

The Super Bowl Indicator is a spurious correlation that says that the stock market's performance in a given year can be predicted based on the outcome of the Super Bowl of that year. It was "discovered" by Leonard Koppett in 1978 when he realized that it had never been wrong, until that point. This pseudo-macroeconomic concept states that if a team from the American Football Conference (AFC) wins, then it will be a bear market, but if a team from the National Football Conference (NFC) or a team that was in the NFL before the NFL/AFL merger wins, it will be a bull market.
Development of solar power in Greece started in 2006 and installations of photovoltaic systems skyrocketed from 2009 because of the appealing feed-in tariffs introduced and the corresponding regulations for domestic applications of rooftop solar PV. In 2019, 90% of the around 2.5 GWp capacity was installed in 2011, 2012 and 2013. However, funding the FITs created an unacceptable deficit of more than €500 million in the Greek "Operator of Electricity Market" RES fund. To reduce that deficit, new regulations were introduced in August 2012 including retrospective feed-in tariffs reduction, with further reductions over time. These measures enabled the deficit to be erased by 2017.
Solar power in France including overseas territories reached an installed capacity figure of 11.2 GW in 2020, and rose further to 17.1 GW at the end of 2022. Government plans announced in 2022 foresee solar PV capacity in France rising to 100 GW by 2050.
The 2015–2016 stock market selloff was the period of decline in the value of stock prices globally that occurred between June 2015 to June 2016. It included the 2015–2016 Chinese stock market turbulence, in which the SSE Composite Index fell 43% in just over two months between June 2015 and August 2015, which culminated in the devaluation of the yuan. Investors sold shares globally as a result of slowing growth in the GDP of China, a fall in petroleum prices, the Greek debt default in June 2015, the effects of the end of quantitative easing in the United States in October 2014, a sharp rise in bond yields in early 2016, and finally, in June 2016, the 2016 United Kingdom European Union membership referendum, in which Brexit was voted upon.
