The fourth asset in our portfolio will be well-known chain of restaurants in the United States, referring to the category of fast casual food, including the Olive Garden, LongHorn Steakhouse, Bahama Breeze and many others. The key difference Darden is an established process and transparency of the company's revenues, though that the network does not include fast-food restaurants. We intentionally do not include in the portfolio shares, which are not traded in US dollars. Despite the diversification of country risk, a greater threat in itself carries a currency risk. In addition to the usual Argentinian, Russian and Brazilian currency devaluations in 2015 there is an unexpected weakening of the currency of such a stable country like Switzerland. Foreign investors, who receive income in Swiss francs, incur large losses. source: marketwatch.comDeveloping countries such as China and India are not better. Waiting for the big news from the Fed and the European Central Bank, we have decided to refrain from foreign investment at this stage. Restaurant business in America is fundamentally different from Russian, because of the different culture of consumption, income and a larger share of the middle class. American restaurants are more resistant to bad economic times.Source: washingtonpost.comWith regard to the company, so over the last four years, the company has grown revenue by 27%. It has also doubled net income from last year. On the earnings front, Darden has beaten estimates for five straight quarters and now projects next year’s earnings at 13%.source: investing.comIn 2015, the company has overstepped all the expected financial results, showing stable growth and leadership in the US market.Best of all, shares were sold off with the rest of the consumer discretionary sector, which means they’re ripe for the picking. Meanwhile, homebuilders have consistently outperformed this year as the housing market picked up. In June, home starts hit a seven-year high. Inventories are tight, and buyers have rushed into deals for homes this summer before interest rates rise, further fueling recovery. Best of all, the uptrend shows few signs of slowing down.Trends in casual dining have remained strong this year as the middle-class, typically the target for casual dining spots, have seen higher disposable incomes due to lower gas prices, rising employment and lower inflation etc. As such, competition has been fierce. To take peers on head-to-head, Darden spun off its less popular Red Lobster unit last summer to focus more on its Olive Garden business. That seems to be paying off, Olive Garden saw overall sales increase 12% last quarter, with same store sales up 3.4%. However, there has been some concern around traffic which was down 2% in the spring, with the chain relying heavily on its regulars. Higher food costs led to an increase of menu prices by 2%. Other well-known chains owned by Darden, such as LongHorn Steakhouse and The Capital Grille have also been doing incredibly well. Since the completion of the sale of Red Lobster, Darden Restaurants’ shares have soared over 55%. Gas is the main "unstable" input element in the business of Darden. Products are purchased from local suppliers under long-term contracts.We can trace some correlation between the price of gas and Darden profit, expressed in share price:It is difficult to predict energy prices for a long period, but the decline in production in developing countries and plenty supply of energy companies do not portend a sharp jump in prices upwards. Moreover, the introduction of electrical grill and alternative energy sources (solar panels) will reduce the dependency on energy prices and stabilize profits in the long run.Diversified chain of restaurants based on traditional American eating habits - an abundance of fried beef, chicken and pork, and fish cuisine in the coastal regions. This policy prevents the re-branding at the exit of the fashion exotic cuisine, as happened for example with the Vietnamese one.On the stability of dividend payments the company stands alone in the value-shares, even when compared with companies such as Coca-Cola, and AT&T:source: investing.com Payments amount to approximately 3.86% compared to 2.7% of the industry.Of further interest is the possibility of a simple hedge, based on key commodities in the business of the company, we will tell about this later in the article about the final derivatives portfolio.
