Can optimal hedge ratio be more than 1?
The larger is the variance of the product used to hedge the lower the hedge ratio. It is even possible that h would be greater than 1.
Hedge ratio is the comparative value of an open position's hedge to the overall position. A hedge ratio of 1, or 100%, means that the open position has been fully hedged. By contrast, a hedge ratio of 0, or 0%, means that the open position hasn't been hedged in any way.
What is the Optimal Hedge Ratio? An optimal hedge ratio is an investment risk management ratio that determines the percentage of a hedging instrument, i.e., a hedging asset or liability that an investor should hedge. The ratio is also popularly known as the minimum variance hedge ratio.
The minimum variance hedge ratio, or optimal hedge ratio, is the product of the correlation coefficient between the changes in the spot and futures prices and the ratio of the standard deviation of the changes in the spot price to the standard deviation of the futures price.
A perfect hedge is one that eliminates all risk in a position or portfolio. In other words, the hedge is 100% inversely correlated to the vulnerable asset. This is more an ideal than a reality on the ground, and even the hypothetical perfect hedge is not without cost.
The hedge ratio calculation requires 3 steps: Determine the value of total exposure. Determine the value of hedge position. Divide the hedge position by the total exposure to get the hedge ratio.
Yes. Correlations max out at 1. However if the correlation is near 1 and the volatility of the spot is significantly larger than the volatility of the future the hedge ratio will be greater than 1.
Optimal Hedge Ratio
Optimal, or the minimum-variance hedge ratio, is a very crucial input in the hedging of risk. It defines the relationship between the sports instrument price and that of the hedging instrument. Therefore, it helps determine the percentage of your portfolio that you should hedge.
The hedge ratio compares the value of a position protected through the use of a hedge with the size of the entire position itself. A hedge ratio may also be a comparison of the value of futures contracts purchased or sold to the value of the cash commodity being hedged.
That may depend on what you think the market might do in the near future. For example, if you strongly believe the stock market will fall 5%–8% over the next three months, an effective hedging strategy that costs less than 5% of your total portfolio's value may be worth consideration.
What is perfect hedge?
What Is a Perfect Hedge? A perfect hedge is a position by an investor that eliminates the risk of an existing position, or a position that eliminates all market risk from a portfolio. Rarely achieved, a perfect hedge position needs to have a 100% inverse correlation to the initial position.
The minimum variance hedge ratio, also known as the optimal hedge ratio, is a formula to evaluate the correlation between the variance in the value of an asset or liability and that of the hedging instrument that is meant to protect it.
Naïve or one-to-one hedge assumes that futures and cash prices move closely together. In this traditional view of hedging, the holding of both the initial spot asset and the futures contract used to offset the risk of the spot asset are of equal magnitude but in opposite direction.
(d) How can the daily settlement of futures contracts be taken into account? The minimum variance hedge ratio is 0.95×0.43/0.40=1.02125. The hedger should take a short position.
There are a number of effective hedging strategies to reduce market risk, depending on the asset or portfolio of assets being hedged. Three popular ones are portfolio construction, options, and volatility indicators.
While risks can seldom be avoided completely, portfolio hedging is one way to protect a portfolio against a potential loss. Hedging stocks does come at a cost but can give investors peace of mind. This can help investors take on enough risk to achieve long-term investment goals.
Hedging against investment risk means strategically using financial instruments or market strategies to offset the risk of any adverse price movements. Put another way, investors hedge one investment by making a trade in another.
To find the delta hedge quantity, you multiply the absolute value of the delta by the number of option contracts by the multiplier. In this case, the quantity is 300, or equal to (0.20 x 15 x 100). Therefore, you must sell this amount of the underlying asset to be delta neutral.
To calculate the test statistic, subtract from one the ratio of the sum of the squared periodic changes in the hedge and the hedged item to the sum of the squared changes in the hedged item. The mean-squared deviation from zero is used because the variance ignores certain types of ineffectiveness.
Hedges may not be perfect because: The quantity to be hedged may differ from the quantity that can be covered by a futures contract. Futures contracts for a particular commodity or for a particular quality of the commodity may not exist.
Is there a perfect hedge in a complete market?
Perfect hedging is a risk management activity that aims at eliminating risk completely. In theory, perfect hedges are possible via dynamic trading in frictionless complete markets and are obtained by standard no-arbitrage methods (e.g., Cvitanic and Zapatero, 2004).
The hedger's gain and loss in the spot and futures market are not fully offset and the hedger will end up with some gain or loss. This is called imperfect hedge. Note that the gain or loss of hedging will be much less than not utilizing hedge.
The sign of hedging ratio shows the position in your portfolio. For instance, negative hedging ratio means that you should take a short position.

It represents the relative weight of the stock in the index. In the above example if all the 5 stocks are weighted to the overall portfolio and then the weighted beta is calculated for each stock, then the total portfolio beta comes to 1.2622. This is called the hedge ratio.
(d) What is the optimal number of futures contracts with tailing of the hedge? The minimum variance hedge ratio is 0.95×0.43/0.40=1.02125. The hedger should take a short position. The optimal number of contracts with tailing is 1.012125×(55,000×28)/(5,000×27)=11.65 (or 12 when rounded to the nearest whole number).
A perfect hedge does not always lead to a better outcome than an imperfect hedge. It just leads to a more certain outcome. Consider a company that hedges its exposure to the price of an asset. Suppose the asset's price movement prove to be favorable to the company.
A perfect hedge refers to a position which an investor undertakes to eliminate the risk of an existing position, or a position which eliminates every market risk from a portfolio. In a bid to be a perfect hedge, a position must have a 100% inverse correlation to the first position. Thus, the perfect is rare to find.
