The caveat is that a forward contract is highly inflexible, because it is a binding contract that the buyer and seller are obligated to execute at the agreed-upon rate. Understanding exchange risk is an increasingly worthwhile exercise in a world where the best investment opportunities may lie overseas.
Consider a U. Because currency moves can magnify investment returns, a U. Of course, at the beginning of , with the Canadian dollar heading for a record low against the U. With the benefit of hindsight, the prudent move in this case would have been to not hedge the exchange risk. However, it is an altogether different story for Canadian investors invested in the U. Hedging exchange risk again, with the benefit of hindsight in this case would have mitigated at least part of that dismal performance.
Interest rate parity is fundamental knowledge for traders of foreign currencies. In order to fully understand the two kinds of interest rate parity, however, the trader must first grasp the basics of forward exchange rates and hedging strategies. Armed with this knowledge, the forex trader will then be able to use interest rate differentials to his or her advantage.

Related Terms Understanding Interest Rate Parity Interest rate parity IRP is a theory according to which the interest rate differential between two countries is equal to the differential between the forward exchange rate and the spot exchange rate. Understanding Uncovered Interest Rate Parity — UIP Uncovered interest rate parity UIP states that the difference in two countries' interest rates is equal to the expected changes between the two countries' currency exchange rates.
Understanding Covered Interest Rate Parity Covered interest rate parity refers to a theoretical condition in which the relationship between interest rates and the spot and forward currency values of two countries are in equilibrium.
The covered interest rate parity means there is no opportunity for arbitrage using forward contracts. Forward Premium A forward premium occurs when the expected future price of a currency is above spot price which indicates a future increase in the currency price. Forex FX Forex FX is the market where currencies are traded and is a portmanteau of "foreign" and "exchange.
Covered Interest Arbitrage Definition Covered interest arbitrage is a strategy where an investor uses a forward contract to hedge against exchange rate risk. Returns are typically small but it can prove effective. Traders and institutions buy and sell currencies 24 hours a day during the week. For a trade to occur, one currency must be exchanged for another. Whatever currency is used will create a currency pair. Access to these forex markets can be found through any of the major forex brokers.
This rate tells you how much it costs to buy one U. To find out how much it costs to buy one Canadian dollar using U. It costs 0. When you go to the bank to convert currencies, you most likely won't get the market price that traders get. The bank or currency exchange house will markup the price so they make a profit, as will credit cards and payment services providers such as PayPal , when a currency conversion occurs.
At the bank though, it may cost 1. The difference between the market exchange rate and the exchange rate they charge is their profit. To calculate the percentage discrepancy, take the difference between the two exchange rates, and divide it by the market exchange rate: 1.
Multiply by to get the percentage markup: 0. A markup will also be present if converting U. They are charging you more U. For most people looking for currency conversion, getting cash instantly and without fees, but paying a markup, is a worthwhile compromise. Shop around for an exchange rate that is closer to the market exchange rate; it can save you money. Some banks have ATM network alliances worldwide, offering customers a more favorable exchange rate when they withdraw funds from allied banks.
Need a foreign currency? Use exchange rates to determine how much foreign currency you want, and how much of your local currency you'll need to buy it. The market rate may be 1. Now assume you want 1, euros, and want to know what it costs in USD.
Multiply 1, by 1. Since we know Euros are more expensive, one euro will cost more than one US dollar, that is why we multiply in this case. Exchange rates always apply to the cost of one currency relative to another. Remember the first currency is always equal to one unit and the second currency is how much of that second currency it takes to buy one unit of the first currency.
From there you can calculate your conversion requirements.
In general, when comparing investment options whose other characteristics are similar, the investment with the highest IRR would probably be considered the best. Excel does all the necessary work for you, arriving at the discount rate you are seeking to find. All you need to do is combine your cash flows, including the initial outlay as well as subsequent inflows, with the IRR function. Here is a simple example of an IRR analysis with cash flows that are known and annually periodic one year apart.
Assume a company is assessing the profitability of Project X. The initial investment is always negative because it represents an outflow. Each subsequent cash flow could be positive or negative, depending on the estimates of what the project delivers or requires as capital injection in the future.
In this case, the IRR is Keep in mind that the IRR is not the actual dollar value of the project. It is the annual return that makes the net present value equal to zero. XIRR is used when the cash flow model does not exactly have annual periodic cash flows.
There are several formulas and concepts that can be used when seeking to identify an expected return. The IRR is generally most ideal for analyzing the potential return of a new project that a company is considering undertaking. You can think of the internal rate of return as the rate of growth an investment is expected to generate annually. Thus, it can be most similar to a compound annual growth rate CAGR.
In reality, an investment will usually not have the same rate of return each year. Usually, the actual rate of return that a given investment ends up generating will differ from its estimated IRR. For example, an energy company may use IRR in deciding whether to open a new power plant or to renovate and expand a previously existing one.
While both projects could add value to the company, it is likely that one will be the more logical decision as prescribed by IRR. Analysis will also typically involve NPV calculations at different assumed discount rates. In theory, any project with an IRR greater than its cost of capital should be a profitable one.
Any project with an IRR that exceeds the RRR will likely be deemed a profitable one, although companies will not necessarily pursue a project on this basis alone. Rather, they will likely pursue projects with the highest difference between IRR and RRR, as these likely will be the most profitable. Market returns can also be a factor in setting a required rate of return.
IRR differs in that it involves multiple periodic cash flows—reflecting the fact that cash inflows and outflows often constantly occur when it comes to investments. ROI tells an investor about the total growth, start to finish, of the investment. It is not an annual rate of return. The two numbers would normally be the same over the course of one year, but they won't be the same for longer periods of time.
Return on investment is the percentage increase or decrease of an investment from beginning to end. It is calculated by taking the difference between the current or expected future value and the original, beginning value, divided by the original value and multiplied by ROI figures can be calculated for nearly any activity into which an investment has been made and an outcome can be measured.
However, ROI is not necessarily the most helpful for long time frames. It also has limitations in capital budgeting, where the focus is often on periodic cash flows and returns. IRR is generally most ideal for use in analyzing capital budgeting projects. It can be misconstrued or misinterpreted if used outside of appropriate scenarios.
In the case of positive cash flows followed by negative ones and then by positive ones, the IRR may have multiple values. However, it is not necessarily intended to be used alone. The IRR itself is only a single estimated figure that provides an annual return value based on estimates.
Scenarios can show different possible NPVs based on varying assumptions. Companies usually compare IRR analysis to other tradeoffs. If another project has a similar IRR with less upfront capital or simpler extraneous considerations then a simpler investment may be chosen despite IRRs. In some cases, issues can also arise when using IRR to compare projects of different lengths. For example, a project of short duration may have a high IRR, making it appear to be an excellent investment.
Conversely, a longer project may have a low IRR, earning returns slowly and steadily. The ROI metric can provide some more clarity in these cases. Though some managers may not want to wait out the longer time frame. Combining foreign and domestic assets together tends to have a magical effect on long-term returns and portfolio volatility; however, these benefits also come with some underlying risks. Several levels of investment risks are inherent in foreign investing: political risk , local tax implications, and exchange rate risk.
Exchange rate risk is especially important because the returns associated with a particular foreign stock or mutual fund with foreign stocks must then be converted into U. Let's break each risk down. Despite the perceived dangers of foreign investing, an investor may reduce the risk of loss from fluctuations in exchange rates by hedging with currency futures.
Simply stated, hedging involves taking on one risk to offset another. Futures contracts are advance orders to buy or sell an asset, in this case, a currency. An investor expecting to receive cash flows denominated in a foreign currency on some future date can lock in the current exchange rate by entering into an offsetting currency futures position. In the currency markets , speculators buy and sell foreign exchange futures to take advantage of changes in exchange rates.
Investors can take long or short positions in their currency of choice, depending on how they believe that currency will perform. For example, if a speculator believes that the euro will rise against the U. This is called having a long position. Conversely, you could argue that the same speculator has taken a short position in the U. There are two possible outcomes with this hedging strategy. If the speculator is correct and the euro rises against the dollar, then the value of the contract will rise too, and the speculator will earn a profit.
However, if the euro declines against the dollar, the value of the contract decreases. When you buy or sell a futures contract, as in our example above, the price of the good in this case the currency is fixed today, but payment is not made until later. Investors trading currency futures are asked to put up margin in the form of cash and the contracts are marked to market each day, so profits and losses on the contracts are calculated each day. Currency hedging can also be accomplished in a different way.
Rather than locking in a currency price for a later date, you can buy the currency immediately at the spot price instead. In either scenario, you end up buying the same currency, but in one scenario you do not pay for the asset upfront. The value of currencies fluctuates with the global supply and demand for a specific currency.
Demand for foreign stocks is also a demand for foreign currency, which has a positive effect on its price. Fortunately, there is an entire market dedicated to the trade of foreign currencies called the foreign exchange market forex, for short. This market has no central marketplace like the New York Stock Exchange ; instead, all business is conducted electronically in what is considered one of the largest liquid markets in the world.
There are several ways to invest in the currency market, but some are riskier than others. Investors can trade currencies directly by setting up their own accounts, or they can access currency investments through forex brokers. However, margined currency trading is an extremely risky form of investment, and is only suitable for individuals and institutions capable of handling the potential losses it entails.
In fact, investors looking for exposure to currency investments might be best served acquiring them through funds or ETFs —and there are plenty to choose from.

Key Takeaways Compound return is the rate of return for capital over a cumulative series of time. Compound returns are a more accurate measure as compared to average returns to calculate growth or decline in an investment over a period of time.
Compare Accounts. The offers that appear in this table are from partnerships from which Investopedia receives compensation. Compound Interest Compound interest is the interest on a loan or deposit calculated based on both the initial principal and and the accumulated interest from previous periods.
Return In finance, a return is the profit or loss derived from investing or saving. Understanding Geometric Mean The geometric mean is the average of a set of products, the calculation of which is commonly used to determine the performance results of an investment or portfolio. Cumulative return is the total change in the price of an investment over a set time period. It is an aggregate figure, not an annualized rate. When considering individual investments or portfolios, a more formal equation for expected return of a financial investment is:.
In essence, this formula states that the expected return in excess of the risk-free rate of return depends on the investment's beta, or relative volatility compared to the broader market. Note that it can be quite dangerous to make naive investment decisions based entirely on expected return calculations. Before making any investment decisions, one should always review the risk characteristics of investment opportunities to determine if the investments align with their portfolio goals.
For example, assume two hypothetical investments exist. Their annual performance results for the last five years are:. Investment A is approximately five times riskier than Investment B. That is, Investment A has a standard deviation of The expected return does not just apply to a single security or asset. If the expected return for each investment is known, the portfolio's overall expected return is a weighted average of the expected returns of its components.
For example, let's assume we have an investor interested in the tech sector. His portfolio contains the following stocks:. Thus, the expected return of the total portfolio is Expected return and standard deviation are two statistical measures that can be used to analyze a portfolio.
The expected return of a portfolio is the anticipated amount of returns that a portfolio may generate, making it the mean average of the portfolio's possible return distribution; whereas the standard deviation of a portfolio measures the amount that the returns deviate from its mean, making it a proxy for the portfolio's risk.
