Portfolio Insurance
Portfolio insurance is a hedging strategy developed to limit the losses an investor might face from a declining index of stocks without having to sell the stocks themselves. The technique was pioneered by Hayne Leland and Mark Rubinstein in 1976. Since its inception, the portfolio insurance strategy has been dubiously marketed as a ''product'' (similar to an insurance policy). However, this is a misnomer as it is not a policy and there is no insurer of last resort. This strategy involves selling futures of a stock index during periods of price declines. The proceeds from the sale of the futures help to offset paper losses of the owned portfolio. This is similar to buying a put option in that it allows an investor to preserve upside gains but limits downside risk. Portfolio insurance is most commonly used by institutional investors when the market direction is uncertain or volatile. In practice, a portfolio insurance strategy uses computer-based models to analyze an op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Put Option
In finance, a put or put option is a derivative instrument in financial markets that gives the holder (i.e. the purchaser of the put option) the right to sell an asset (the ''underlying''), at a specified price (the ''strike''), by (or at) a specified date (the ''expiry'' or ''maturity'') to the ''writer'' (i.e. seller) of the put. The purchase of a put option is interpreted as a negative sentiment about the future value of the underlying stock. page 15 , 4.2.3 Positive and negative sentiment The term "put" comes from the fact that the owner has the right to "put up for sale" the stock or index. Puts may also be combined with other derivatives as part of more complex investment strategies, and in particular, may be useful for hedging. Holding a European put option is equivalent to holding the corresponding call option and selling an appropriate forward contract. This equivalence is called " put-call parity". Put options are most commonly used in the stock market to protect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institutional Investor
An institutional investor is an entity which pools money to purchase securities, real property, and other investment assets or originate loans. Institutional investors include commercial banks, central banks, credit unions, government-linked companies, insurers, pension funds, sovereign wealth funds, charities, hedge funds, REITs, investment advisors, endowments, and mutual funds. Operating companies which invest excess capital in these types of assets may also be included in the term.

In 2019, the world's top 500 asset managers collectively managed $104.4 trillion in Assets under Management (AuM). Although institutional investors appear to be more sophisticated than retail investors, it remains unclear if professional active investment managers can reliably enhance risk-adjusted returns by an amount that exceeds fees and expenses of investment managemen ...

Volatility (finance)
In finance, volatility (usually denoted by ''σ'') is the degree of variation of a trading price series over time, usually measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Volatility terminology Volatility as described here refers to the actual volatility, more specifically: * actual current volatility of a financial instrument for a specified period (for example 30 days or 90 days), based on historical prices over the specified period with the last observation the most recent price. * actual historical volatility which refers to the volatility of a financial instrument over a specified period but with the last observation on a date in the past **near synonymous is realized volatility, the square root of the realized variance, in turn calculated using the sum of squ ...

Index Arbitrage
Index arbitrage is a subset of statistical arbitrage focusing on index components. An index (such as S&P 500) is made up of several components (in the case of the S&P 500, 500 large US stocks picked by S&P to represent the US market), and the value of the index is typically computed as a linear function of the component prices, where the details of the computation (such as the weights of the linear function) are determined in accordance with the index methodology. The idea of index arbitrage is to exploit discrepancies between the market price of a product that tracks the index (such as a Stock market index future or Exchange-traded fund) and the market prices of the underlying index components, which are typically stocks. For example, an arbitrageur could take the current prices of traded stocks, calculate a synthetic index value using the relevant index methodology, and then apply an interest rate and dividend adjustment to calculate the "fair value" of the stock market index f ...

Program Trading
Program trading is a type of trading in 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 (1987)
Black Monday is the name commonly given to the global, sudden, severe, and largely unexpected stock market crash on Monday, October 19, 1987. In Australia and New Zealand, the day is also referred to as ''Black Tuesday'' because of the time zone difference from other English-speaking countries. All of the twenty-three major world markets experienced a sharp decline in October 1987. When measured in United States dollars, eight markets declined by 20 to 29%, three by 30 to 39% (Malaysia, Mexico and New Zealand), and three by more than 40% (Hong Kong, Australia and Singapore). The least affected was Austria (a fall of 11.4%) while the most affected was Hong Kong with a drop of 45.8%. Out of twenty-three major industrial countries, nineteen had a decline greater than 20%. Worldwide losses were estimated at US$1.71 trillion. The severity of the crash sparked fears of extended economic instability or even a reprise of the Great Depression. The degree to which the stock market crashe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
