Richard Arms invented the analysis tool that bears his name in 1967. The Arms Index, a technical analysis indicator, is also called the TRIN (short for “Trading Index”) because it seeks to indicate overbought or oversold conditions by serving as an index of trading activity relative to price. The Arms index is calculated using readily available data from major indexes such as the S&P 500 or NASDAQ. The ratio of the number of advancing stocks (stocks whose prices are increasing) to the number of declining stocks (stocks whose prices are decreasing) is computed to give us the A/D Ratio, a market breadth indicator that is one way of viewing the daily breadth of a security. The Advance/Decline Ratio uses the same numbers as the Advance/Decline Line but presents them as a ratio instead. The AD Ratio is sometimes more useful than an AD Line, including in instances where comparing AD for different indexes which have different metrics; the ratio is the standardization with which comparisons can be made.

The Ease of Movement (EMV) indicator measures the degree to which prices can be moved by a lower volume of trading. It was developed by Richard Arms, inventor of the Arms Index, which also attempts to quantify the relationship between price movements and volume. High positive values indicate a present tendency for prices to increase on low volume, and larger negative values indicate that prices are slipping lower but with relatively low trade volume. Continue reading...
Market indexes attempt to give an overall picture of the behavior of the market by tracking the performance of a representative sample of stocks. Different indexes have different focuses. The Russell 3000 samples more of the smaller companies than the S&P 500. Index mutual funds and ETFs track specific indexes but, as you’ll notice in their disclosures, it is impossible to invest directly in an index; they only follow the index by investing in as many of the companies as possible and minimizing lag as much as they can. Indexes give numerical values for the progressive fluctuations in the price action for specific sets of stocks. Continue reading...
The MSCI ACWI is the “All Country World Index” - providing the broadest measure for global stocks. The MSCI ACWI tracks performance of stocks from all over the world - literally. It includes all markets and gives the broadest picture for how world stocks are performing. Developed markets account for some 75% of total global output, so the MSCI ACWI includes many countries that are not necessarily palatable contributors to world growth. Continue reading...
Social Security retirement benefits are computed by finding the average monthly income of a worker during the highest-earning 35 years of employment, and then it plugs that amount into a formula for to determine their full benefit at Normal Retirement Age (NRA). A person may then choose to take benefits before or after NRA, with applicable reductions or additions. There are different equations for spousal benefits, survivor’s benefits, and maximum family benefits. Continue reading...
Social Security uses a formula that applies a factor to your average monthly income from the 35 years in which you earned the most. The benefit will be calculated for your Normal Retirement Age (67 for most people today), and you should receive statements in the mail keeping you updated on your projected or actual Social Security Retirement Benefits. Every year, you should get a statement from the Social Security Administration that provides you with exact numbers. The amount depends on the age at which you retire, and the contributions you made to Social Security over the years. The formula uses the 35 years in which you earned the most, and divides it by the total number of months in 35 years, which is 420, which leads to your Average Indexed Monthly Earnings (AIME). Continue reading...
A mortgage whose rate is variably adjusted according to the interest rate environment is known as an ARM. With an adjustable rate mortgage (ARM) , the interest rate is lower at the beginning than the fixed-rate alternative, but the customer bears the risk of interest rates going up in the future. The bank or institution creating such a product will usually peg the rate to a specific index or benchmark rate, and will also probably give the customer a cap at which rate hikes would stop. Continue reading...
The main idea behind index investing is that markets are efficient, and, especially with the low fees of indexed funds, it can be a winning strategy. Index investing is a simple strategy of choosing the indices which reflect your investment beliefs and offer diversification, buying mutual funds or ETFs that track these indices, and holding them for a long period of time. The last 10 years have seen the propagation of index funds for any specific market, industry, country, commodity, etc. Continue reading...
Index futures are futures contracts written on an index in which a large position can be held with a relatively small margin requirement. Index futures can be used for hedging or speculation. A "good faith" initial margin deposit (also called a performance bond) of a fraction of the contract size is all that is required to hold a substantial position, with a notional value worth significantly more than the amount invested. Continue reading...
Most index funds are known for using a completely passive strategy to track an index, but some take a more active approach. Some mutual funds track an index by passively using algorithms to buy the shares necessary to build a portfolio which closely replicates an index. Such a fund will have low turnover, will only rebalance slightly based on the market cap or other criteria set forth in the prospectus, and will basically ride out all of the ups and downs of the index in a blind faith for the efficient market hypothesis. Continue reading...
Market Breadth is a descriptor that is used in several market indicators such as the daily breadth, the A/D Line, the McClellan Oscillator, and Arms Index. Breadth is the relative difference in the amount of advancing stocks and declining stocks. Daily breadth is simply computed by subtracting one from the other, or creating a ratio in which one is divided by the other. Daily breadth is closely related, even interchangeable, with the Advance/Decline ratio. It can also refer to the difference between New Highs and New Lows, or Net New Highs. Continue reading...
When creating an index, it must be decided what criteria will affect the value of the index, and in the case of a price-weighted index, the only consideration is the price of shares. A price-weighted index is created by adding up the individual price per share of the companies included in the index and dividing by the number of companies. Essentially what you've done is arrived at the average price per share of the companies included in the index. Continue reading...
Commodity indexes are also called commodity price indexes, and they are informational services which reflect the price action in a designated commodity or basket of commodities. Indexes are often tracked by mutual funds or ETFs, and these can be confused with the actual index. Indexes are computed and published by market research firms. They can serve as benchmarks against which the performance of a specific asset or an investment portfolio can be compared, or they can serve as the model that index funds seek to emulate. Continue reading...
The Accumulative Swing Index (ASI) is a trendline representing the running total of an oscillator called the Swing Index, first described by Webb Wilder in his book, “New Concepts in Technical Trading Systems.” The Swing Index itself compares the price data from the current period and the preceding period to quantify the positive or negative “swing,” which can be understood as a measure of directional velocity in a price. Continue reading...
The House Price Index (HPI) tracks average prices of homes using data from sales and refinancing, tracking the data for the same residential properties over many years. The Federal Housing Finance Agency (FHFA) publishes it quarterly and relies on data from Fannie Mae and Freddie Mac. The HPI is an important index for the real estate and mortgage industry, as well as the economy as a whole. It uses information from Fannie Mae and Freddie Mac about home sale prices and the refinancing value of homes, tracking the sales and refinancing prices of homes in the Fannie Mae and Freddie Mac databases, all the way back to 1978. They do this using a weighted repeat-sales method. It is published quarterly by the Federal Housing Finance Agency (FHFA). Continue reading...
The Positive Volume Index (PVI) is a technical indicator that tracks increases in trade volume for an index or security, as well as the changes in price on those days. Paul Dysart developed the original version of this indicator for market indexes using advance-decline numbers instead of prices. The Positive Volume Index was then redesigned by Norman Fosback for individual securities – the version commonly used today. Continue reading...
The Negative Volume Index (NVI) is a technical indicator that tracks decreases in trade volume for an index or security, as well as price changes on those days. Paul Dysart developed the original version of this indicator for market indexes, and it garnered renewed attention when it was reworked in the 1970s via Norman Fosback in his book Stock Market Logic. The price changes in a security or the percentage change in an index are only added to or subtracted from the Negative Volume Index on days when the trading volume is lower than the day before. By watching market movement on days with lower trading volume, investors can identify where institutions and fund managers are moving their money. If trading volume is down and the market continues to do well, it means that there is a strong bullish primary trend, and that trading volume is not artificially pushing prices around. Continue reading...
The Wilshire 5000 is about as broad as an index gets. There are over 9,000 companies traded on all of the U.S. equity markets, and the Wilshire 5000 tries to capture a broad sense for how they are performing. Though the index says 5000, there are actually just under 7,000 listed stocks in the index. It is a cap-weighted index meaning bigger stocks have more influence, and vice versa. It can be considered the broadest index of all U.S. equity markets. Continue reading...
The Commodity Selection Index (CSI) is a momentum indicator based on the Directional Movement Indicator and the Average True Range. It helps commodities traders find momentum in commodities futures that seem to be the best candidates to make the trader money in the short term, based on volatility and also the cost of holding the position. This momentum indicator uses multiple other indicators for price, volume, and volatility to find short term trends. It may identify situations where a price movement is likely to persist. This is certainly not a guarantee, and even if a trend is strong there are often retracements and unexpected reversals. Continue reading...
MSCI Inc. is a company that is best known for its global indices. MSCI also provides research and pricing capabilities to institutional investors. MSCI was formerly a branch of Morgan Stanley, but grew to be so big that they spun off and formed the independent company, MSCI Inc. Perhaps its best known and used index is the MSCI EAFE, which tracks broad performance of Europe, Asia, and the Far East. Continue reading...
