Return On Equity Adalah

A More Sophisticated Calculation Of Roa

How Return on Equity Works

ROE is considered a measure of how effectively management is using a company’s assets to create profits.

ROE is expressed as a percentage and can be calculated for any company if net income and equity are both positive numbers. Net income is calculated before dividends paid to common shareholders and after dividends to preferred shareholders and interest to lenders.

$\begin{matrix} Return on Equity = \frac{Net Income}{Average Shareholders’ Equity} \end{matrix}$ Return on Equity=Average Shareholders’ EquityNet Income

Net Income is the amount of income, net of expense, and taxes that a company generates for a given period. Average Shareholders' Equity is calculated by adding equity at the beginning of the period. The beginning and end of the period should coincide with that which the net income is earned.

Net income over the last full fiscal year, or trailing 12 months, is found on the income statement—a sum of financial activity over that period. Shareholders' equity comes from the balance sheet—a running balance of a company’s entire history of changes in assets and liabilities.

It is considered the best practice to calculate ROE based on average equity over the period because of this mismatch between the two financial statements. Learn more about how to calculate ROE.

Return on equity (ROE) deemed good or bad will depend on what’s normal for a stock’s peers. For example, utilities will have a lot of assets and debt on the balance sheet compared to a relatively small amount of net income. A normal ROE in the utility sector could be 10% or less. A technology or retail firm with smaller balance sheet accounts relative to net income may have normal ROE levels of 18% or more.

A good rule of thumb is to target an ROE that is equal to or just above the average for the peer group. For example, assume a company, TechCo, has maintained a steady ROE of 18% over the last few years compared to the average of its peers, which was 15%. An investor could conclude that TechCo’s management is above average at using the company’s assets to create profits.

Relatively high or low ROE ratios will vary significantly from one industry group or sector to another. When used to evaluate one company to another similar company the comparison will be more meaningful. A common shortcut for investors to consider a return on equity near the long-term average of the S&P 500 (14%) as an acceptable ratio and anything less than 10% as poor.

Sustainable growth rates and dividend growth rates can be estimated using ROE assuming that the ratio is roughly in line or just above its peer group average. Although there may be some challenges, ROE can be a good starting place for developing future estimates of a stock’s growth rate and the growth rate of its dividends. These two calculations are functions of each other and can be used to make an easier comparison between similar companies.

To estimate a company’s future growth rate, multiply ROE by the company’s retention ratio. The retention ratio is the percentage of net income that is “retained” or reinvested by the company to fund future growth.

Assume that there are two companies with an identical ROE and net income, but different retention ratios. Company A has an ROE of 15% and returns 30% of its net income to shareholders in a dividend, which means company A retains 70% of its net income. Business B also has an ROE of 15% but returns only 10% of its net income to shareholders for a retention ratio of 90%.

For company A, the growth rate is 10.5%, or ROE times the retention ratio, which is 15% times 70%. business B's growth rate is 13.5%, or 15% times 90%.

This analysis is referred to as the sustainable growth rate model. Investors can use this model to make estimates about the future and to identify stocks that may be risky because they are running ahead of their sustainable growth ability. A stock that is growing slower than its sustainable rate could be undervalued, or the market may be discounting risky signs from the company. In either case, a growth rate that is far above or below the sustainable rate warrants additional investigation.

This comparison seems to make business B look more attractive than company A, but it ignores the advantages of a higher dividend rate that may be favored by some investors. We can modify the calculation to make an estimate of the stock’s dividend growth rate which may be more important to income investors.

Continuing with our example from above, the dividend growth rate can be estimated by multiplying ROE by the payout ratio. The payout ratio is the percentage of net income that is returned to common shareholders through dividends. This formula gives us a sustainable dividend growth rate, which favors company A.

The company A dividend growth rate is 4.5%, or ROE times payout ratio, which is 15% times 30%. Business B's dividend growth rate is 1.5%, or 15% times 10%. A stock that is growing its dividend far above or below the sustainable dividend growth rate may indicate risks that need to be investigated.

It’s reasonable to wonder why an average or slightly above average ROE is good rather than an ROE that is double, triple, or even higher the average of their peer group. Aren’t stocks with a very high ROE a better value?

Sometimes an extremely high ROE is a good thing if net income is extremely large compared to equity because a company’s performance is so strong. However, more often an extremely high ROE is due to a small equity account compared to net income, which indicates risk.

Inconsistent Profits

The first potential issue with a high ROE could be inconsistent profits. Imagine a company, LossCo, that has been unprofitable for several years. Each year’s losses are on the balance sheet in the equity portion as a “retained loss.” The losses are a negative value and reduce shareholder equity. Assume that LossCo has had a windfall in the most recent year and has returned to profitability. The denominator in the ROE calculation is now very small after many years of losses which makes its ROE misleadingly high.

Excess Debt

Second is excess debt. If a company has been borrowing aggressively, it can increase ROE because equity is equal to assets minus debt. The more debt a company borrows, the lower equity can fall. A common scenario that can cause this issue occurs when a company borrows large amounts of debt to buy back its own stock. This can inflate earnings per share (EPS), but it doesn’t affect actual growth rates or performance.

Negative Net Income

Finally, there’s negative net income and negative shareholder equity that can lead to an artificially high ROE. However, if a company has a net loss or negative shareholders’ equity, ROE should not be calculated.

If shareholders’ equity is negative, the most common issue is excessive debt or inconsistent profitability. However, there are exceptions to that rule for companies that are profitable and have been using cash flow to buy back their own shares. For many companies, this is an alternative to paying dividends and it can eventually reduce equity (buybacks are subtracted from equity) enough to turn the calculation negative.

In all cases, negative or extremely high ROE levels should be considered a warning sign worth investigating. In rare cases, a negative ROE ratio could be due to a cash flow supported share buyback program and excellent management, but this is the less likely outcome. In any case, a company with a negative ROE cannot be evaluated against other stocks with positive ROE ratios.

While return on equity looks at how much in profit a company can generate relative to shareholders’ equity, return on invested capital (ROIC) takes that calculation a couple of steps further.

The purpose of ROIC is to figure out the amount of money after dividends a company makes based on all its sources of capital, which includes shareholders equity and debt. ROE looks at how well a company utilizes shareholder equity, while ROIC is meant to determine how well a company uses all its available capital to make money.

A high return on equity might not always be positive. An outsized ROE can be indicative of a number of issues—such as inconsistent profits or excessive debt. As well, a negative ROE, due to the company having a net loss or negative shareholders’ equity, cannot be used to analyze the company. Nor can it be used to compare against companies with a positive ROE.

For example, imagine a company with an annual income of $1,800,000 and average shareholders' equity of $12,000,000. This company’s ROE would be as follows:

$R O E = (\frac{$ 1, 800, 000}{$ 12, 000, 000}) = 15 %$ ROE=($12,000,000$1,800,000)=15%

Consider Apple Inc. (AAPL)—for the fiscal year ending Sept. 29, 2018, the company generated US$59.5 billion in net come. At the end of the fiscal year, it’s shareholders’ equity was $107.1 billion versus $134 billion at the beginning. Apple’s return on equity, therefore, is 49.4%, or $59.5 billion / (($107.1 billion + $134 billion) / 2).

Compared to its peers, Apple has a very strong ROE.
