What Is Annual Turnover?

Annual turnover is the percentage rate at which something changes ownership over the course of a year. For a business, this rate could be related to its yearly turnover in inventories, receivables, payables, or assets.

In investments, a mutual fund or exchange-traded fund (ETF) turnover rate replaces its investment holdings on a yearly basis. Portfolio turnover is the comparison of assets under management (AUM) to the inflow, or outflow, of a fund’s holdings. The figure is useful to determine how actively the fund changes the underlying positions in its holdings. High figure turnover rates indicate an actively managed fund. Other funds are more passive and have a lower percentage of holding turnovers. An index fund is an example of a passive holding fund.

Calculating Annual Turnover

To calculate the portfolio turnover ratio for a given fund, first determine the total amount of assets purchased or sold (whichever happens to be greater), during the year. Then, divide that amount by the average assets held by the fund over the same year.


$\begin{aligned}&\text{portfolio turnover}\ =\ \frac{\operatorname{max}\begin{cases} \text{fund purchases}\\ \quad \text{fund sales}\end{cases}}{\text{average assets}}\end{aligned}$​portfolio turnover = average assetsmax{fund purchasesfund sales​​​

For example, if a mutual fund held $100 million in assets under management (AUM) and $75 million of those assets were liquidated at some point during the measurement period, the calculation is:


$\begin{aligned}&\frac{\$75\text{m}}{\$100\text{m}}=0.75\\&\textbf{where:}\\&\text{m}=\text{million}\end{aligned}$​$100m$75m​=0.75where:​

It is important to note that a fund turning over at 100% annually has not necessarily liquidated all positions with which it began the year. Instead, the complete turnover accounts for the frequent trading in and out of positions and the fact that sales of securities equal total AUM for the year. Also, using the same formula, the turnover rate is also measured by the number of securities bought in the measurement period.

Annualized Turnover in Investments

Annualized turnover is a future projection based on one month—or another shorter period of time—of investment turnover. For example, suppose that an ETF has a 5% turnover rate for the month of February. Using that figure, an investor may estimate annual turnover for the coming year by multiplying the one-month turnover by 12. This calculation provides an annualized holdings turnover rate of 60%.

Actively Managed Funds

Growth funds rely on trading strategies and stock selection from seasoned professional managers who set their sights on outperforming the index against which the portfolio benchmarks. Owning large equity positions is less about a commitment to corporate governance than it is a means to positive shareholder results. Managers who consistently beat the indices stay on the job and attract significant capital inflows.

While the passive versus active management argument persists, high volume approaches can realize moderate success. Consider the American Century Small Cap Growth fund (ANOIX), a four-star-rated Morningstar fund with a frantic 141% turnover rate (as of February 2021) that outperformed the S&P 500 Index considently over the last 15 years (through 2021).

Passively Managed Funds

Index funds, such as the Fidelity 500 Index Fund (FXAIX), adopt a buy-and-hold strategy. Following this system, the fund owns positions in equities as long as they remain components of the benchmark. The funds maintain a perfect, positive correlation to the index, and thus, the portfolio turnover rate is just 4%. Trading activity is limited to purchasing securities from inflows and infrequently selling issues removed from the index. More than 60% of the time, indices have historically outpaced managed funds.

Also, it is important to note, a high turnover rate judged in isolation is never an indicator of fund quality or performance. The Fidelity Spartan 500 Index Fund, after expenses, trailed the S&P 500 by 2.57% in 2020.

Annual Turnover in Business: Inventory Turnover

Businesses use several annual turnover metrics for understanding how well the business is running on a yearly basis. Inventory turnover measures how fast a company sells inventory and how analysts compare it to industry averages. A low turnover implies weak sales and possibly excess inventory, also known as overstocking. It may indicate a problem with the goods being offered for sale or be a result of too little marketing. A high ratio implies either strong sales or insufficient inventory. The former is desirable while the latter could lead to lost business. Sometimes a low inventory turnover rate is a good thing, such as when prices are expected to rise (inventory pre-positioned to meet fast-rising demand) or when shortages are anticipated.

The speed at which a company can sell inventory is a critical measure of business performance. Retailers that move inventory out faster tend to outperform. The longer an item is held, the higher its holding cost will be, and the fewer reasons consumers will have to return to the shop for new items.

What Is the Aroon Indicator?

The Aroon indicator is a technical indicator that is used to identify trend changes in the price of an asset, as well as the strength of that trend. In essence, the indicator measures the time between highs and the time between lows over a time period. The idea is that strong uptrends will regularly see new highs, and strong downtrends will regularly see new lows. The indicator signals when this is happening, and when it isn’t.

The indicator consists of the “Aroon up” line, which measures the strength of the uptrend, and the “Aroon down” line, which measures the strength of the downtrend.

The Aroon indicator was developed by Tushar Chande in 1995.

Formulas for the Aroon Indicator


$\begin{aligned} \text{Aroon Up}&= \frac{25-\text{Periods Since 25 period High}}{25} \ast100\\ \text{Aroon Down}&=\frac{25-\text{Periods Since 25 period Low}}{25}\ast100 \end{aligned}$Aroon UpAroon Down​=2525−Periods Since 25 period High​∗100=2525−Periods Since 25 period Low​∗100​

How to Calculate the Aroon Indicator

The Aroon calculation requires the tracking of the high and low prices, typically over 25 periods.

1. Track the highs and lows for the last 25 periods on an asset.
2. Note the number of periods since the last high and low.
3. Plug these numbers into the Up and Down Aroon formulas.

What Does the Aroon Indicator Tell You?

The Aroon Up and the Aroon Down lines fluctuate between zero and 100, with values close to 100 indicating a strong trend and values near zero indicating a weak trend. The lower the Aroon Up, the weaker the uptrend and the stronger the downtrend, and vice versa. The main assumption underlying this indicator is that a stock’s price will close regularly at new highs during an uptrend, and regularly make new lows in a downtrend.

The indicator focuses on the last 25 periods, but is scaled to zero and 100. Therefore, an Aroon Up reading above 50 means the price made a new high within the last 12.5 periods. A reading near 100 means a high was seen very recently. The same concepts apply to the Down Aroon. When it is above 50, a low was witnessed within the 12.5 periods. A Down reading near 100 means a low was seen very recently.

Crossovers can signal entry or exit points. Up crossing above Down can be a signal to buy. Down crossing below Up may be a signal to sell.

When both indicators are below 50 it can signal that the price is consolidating. New highs or lows are not being created. Traders can watch for breakouts as well as the next Aroon crossover to signal which direction price is going.

Example of How to Use the Aroon Indicator

The following chart shows an example of the Aroon indicator and how it can be interpreted.

In the chart above, there is both the Aroon indicator and an oscillator that combines both lines into a single reading of between 100 and -100. The crossover of the Aroon Up and Aroon Down indicated a reversal in the trend. While the index was trending, prior to the reversal, the Aroon Down remained very low, suggesting that the index had a bullish bias. Despite the rally on the far right, the Aroon indicator hasn’t shown a bullish bias yet. This is because the price rebounded so quickly that it hasn’t made a new high in the last 25 periods (at the time of the screenshot), despite the rally.

The Difference Between the Aroon Indicator and the Directional Movement Index (DMI)

The Aroon indicator is similar to the Directional Movement Index (DMI) developed by Welles Wilder. It too uses up and down lines to show the direction of a trend. The main difference is that the Aroon indicator formulas are primarily focused on the amount of time between highs and lows. The DMI measures the price difference between current highs/lows and prior highs/lows. Therefore, the main factor in the DMI is price, and not time.

Limitations of Using the Aroon Indicator

The Aroon indicator may at times signal a good entry or exit, but other times it will provide poor or false signals. The buy or sell signal may occur too late, after a substantial price move has already occurred. This happens because the indicator is looking backwards, and isn’t predictive in nature.

A crossover may look good on the indicator, but that doesn’t mean the price will necessarily make a big move. The indicator isn’t factoring the size of moves, it only cares about the number of days since a high or low. Even if the price is relatively flat, crossovers will occur as eventually a new high or low will be made within the last 25 periods. Traders still need to use price analysis, and potentially other indicators, to make informed trading decisions. Relying solely on one indicator isn’t advised.

What Is Absolute Return?

Absolute return is the return that an asset achieves over a specified period. This measure looks at the appreciation or depreciation, expressed as a percentage, that an asset, such as a stock or a mutual fund, achieves over a given period.

Absolute return differs from relative return because it is concerned with the return of a particular asset and does not compare it to any other measure or benchmark.

How Absolute Return Works

Absolute return refers to the amount of funds that an investment has earned. Also referred to as the total return, the absolute return measures the gain or loss experienced by an asset or portfolio independent of any benchmark or other standard. Returns can be positive or negative and may be considered uncorrelated to other market activities.

Relative and Absolute Returns

In general, a mutual fund seeks to produce returns that are better than its peers, its fund category, and the market as a whole. This type of fund management is referred to as a relative return approach to fund investing. The success of the asset is often based on a comparison to a chosen benchmark, industry standard, or overall market performance.

As an investment vehicle, an absolute return fund seeks to make positive returns by employing investment management techniques that differ from traditional mutual funds. Absolute return investment strategies include using short selling, futures, options, derivatives, arbitrage, leverage, and unconventional assets. Absolute returns are examined separately from any other performance measure, so only gains or losses on the investment are considered.

The History of Absolute Return Funds

Alfred Winslow Jones is credited with forming the first absolute return fund in New York in 1949. In recent years, the absolute return approach to fund investing has become one of the fastest-growing investment products in the world and is more commonly referred to as a hedge fund.

Hedge Funds

A hedge fund is not a specific form of investment; it is an investment structured as a pool and set up as either a limited partnership or limited liability company (LLC). A hedge fund manager raises funds by working with outside investors. The manager uses the funds to invest based on a declared strategy involving only the purchase of long equities, such as common stock.

Hedge funds may specialize in specific areas, such as real estate or patents, and may also engage in private equity activities. While anyone may invest in a hedge fund, participants are traditionally accredited and sophisticated investors.

Example of Absolute Return

As a historical example, the Vanguard 500 Index ETF (VOO) delivered an absolute return of 150.15% over the 10-year period ending Dec. 31, 2017. This differed from its 10-year annualized return of 8.37% over the same period. Further, because the S&P 500 Index had an absolute return of 153.07% over the same period, absolute return differed from the relative return, which was -2.92%. 

What Is the 11th District Cost of Funds Index?

The 11th District Cost of Funds Index (COFI) is a monthly weighted average of the interest rates paid on checking and savings accounts offered by financial institutions operating in Arizona, California, and Nevada. It is one of many indices used by mortgage lenders to adjust the interest rate on adjustable rate mortgages (ARM) and was launched in 1981. With an ARM mortgage, the interest rate on a mortgage moves up and down along with some standard interest rate chosen by the lender, and COFI is one of the most popular indices in the western states.

Published on the last day of each month, the COFI represents the cost of funds for western savings institutions that are members of Federal Home Loan Bank of San Francisco, a self-regulatory agency, and satisfy the Bank’s criteria for inclusion in the index.

Understanding the 11th District COFI

The 11th District Cost of Funds Index (COFI) is computed using several different factors, with interest paid on savings accounts comprising the largest weighting in the average. As a result, the index tends to have low volatility and follow market interest rate changes somewhat slowly; it is generally regarded as a two-month lagging indicator of market interest rates. The interest rate on a mortgage will not match the COFI, rather the ARM rate is typically 2% to 3% higher than COFI, depending on the borrower’s credit history, the size and terms of the loan, the ability of the borrower to negotiate with the bank and many other factors.

Because it is computed using data from three western states, the COFI is primarily used in the western U.S., while the 1-year Treasury index is the measure of choice in the eastern region. On April 30, the Federal Home Loan Bank of San Francisco announced the COFI for March 2018 of 0.814%, slightly lower than February.
