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.

Volume is a count of trades in a security or market, or their derivative instruments and can be indicative of trends and sentiment. Volume is the number of trades in a security or market in a given time. Trade volume is important because it helps analysts pick apart the factors driving a trend or get an idea of the strength of a trend. Potential buyers and sellers can push the Bid and Ask prices around at will, hypothetically, but a trade only occurs when the buyer and seller transact business; also, even only a minimal number of trades can move prices around, but this is not indicative of a strong trend — a few trades more and the price is where it was before. Continue reading...
On-Balance Volume (OBV) is a popular leading indicator introduced in the 1960s by Joe Granville. OBV is a line built using differences between daily trading volume – in Granville’s estimation, the major driver of market behavior – adding the difference on days that the market or stock moves up and subtracting the difference on days when the market or stock moves down. It looks for instances of rising volume that should correlate with price movement, but price movement has not occurred; additionally, OBV can be used to confirm lag. 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...
A short position is a sale made by an investor for a security which he or she will deliver to the buyer in the near future, but which he or she is hoping will go down in price in the near future so that a profit can be retained from the price collected in the short sale. A short position is a bearish play on a security which an investor believes will decrease in price in the near future. The investor offers shares for sale, and collects the current market price for the shares from the buyer. Continue reading...
A long position - or to be “long a stock” - means that an investor has share ownership and will receive an economic benefit if the share price rises, and vice versa. Creating and maintaining a long position is simple: an investor just buys and owns the investment. A “long-only” strategy refers to an asset manager that only buys and sells securities in the portfolio as a management strategy - they will not use options or shorting strategies as a result. Continue reading...
The Volume Weighted Average Price (VWAP) helps traders consider the influence of volume on prices. VWAP is calculated by taking the average of prices from a time period and dividing it by the trading volume for the current day. Traders use VWAP to confirm trends and decide whether to take long or short positions, while large institutions are likely to use VWAP to avoid disrupting market prices, finding the liquid and illiquid price points and trading so as not to move prices away from the averages. 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...
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...
A long position in a security means owning shares and having a positive investment balance in a stock, bond, commodity, etc. This is done by simply buying and owning the investment. An investor with a long position in a stock will benefit financially when the price of the stock rises. What is a Short Position? What is Short Selling? Continue reading...
To be “long” means to own a security, and to essentially be bullish on it. A long position is to own a security and to expect it to appreciate. When people buy stocks, they are “long” those stocks. Listening to fund managers giving market commentary, you may hear them say they are “long” on China or Industrials or Apple Inc., and this means that even though they may have hedged their position with some “short” sales, their outlook for those markets is optimistic and their bullish bets outweigh their bearish ones. 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...
Taking a short position is selling a security that you don’t own because you anticipate that its value is set to fall. In simple terms, an investor that takes a short position is betting against it. “Shorting” is the opposite of being “long” in a security, where being “long” means to actually own it and to wait for it to appreciate. When you contact your broker or custodian to take a short position on a security, you essentially sell shares you don’t own, and then after a period, you have to return those shares to the custodian. Continue reading...
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.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...
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...
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...
