First, it is very difficult for a government to support its citizens if there is no stability. If a country is considered politically unstable, the people who run the country are going to be more concerned about keeping themselves in power and less concerned about providing the necessary support for its people. Furthermore, political stability is important because it allows countries to form alliances with others. If a country is deemed politically unstable, it will be difficult for other countries to take the leader of that country seriously. Finally, political stability is also important from a safety perspective.

NerdWallet, Inc. does not offer advisory or brokerage services, nor does it recommend or advise investors to buy or sell particular stocks, securities or other investments. The free-float adjusted market capitalizations for all constituent stocks are summed to obtain the total market capitalization of the S&P 500. It is then divided by an index divisor, which is a proprietary figure developed by S&P.The divisor is adjusted to reflect stock splits, special dividends, and spinoffs that could affect the value of the index. The divisor ensures that these non-economic factors do not affect the index. Although ESG funds appeal to those who want to invest with a conscience, a strong ESG focus is also good for returns. Companies that pose little ESG-related risk often deliver superior financial performance, making ESG funds, such as the Fidelity U.S. Sustainability Index Fund, a good choice for long-term investors.

In addition to bonds, a stable value fund also invests in insurance contracts that are issued by insurance companies or banks. For stable value funds the insurance is designed to make sure that no matter what is going on with interest rates, the value of the fund will not fall. Like a money market mutual fund, stable value funds aim to always maintain a net asset value (NAV) of $1.00 per share. A stable value fund is a low-risk investment (like a money market fund) that delivers higher yields (like a bond fund).

These tend to be good choices because they’re well diversified and allow you to lock in the historical growth of the domestic stock market. However, higher rewards come with greater risk, and dividend payments will likely be minimal. If you want investment income, a dividend fund like the SPDR S&P Dividend ETF is a good choice.

• In 2022, the fund fell more than 18%, almost identical to the S&P 500’s losses for the year.
• So, it’s unsurprising that the SPDR S&P 500 Dividend ETF had much smaller losses than the S&P 500 in 2022 or that it underperformed compared to the S&P 500 in 2023 and the first four months of 2024.

The ETF is underweighted in tech stocks, which don’t tend to pay generous dividends. Over the past thirty years, various macro codes have been released by researchers to compute some stability statistics. Piepho [105] published the first SAS’s code, which only was able to calculate the Shukla’s stability variance (σ2), coefficient of variance (CV), and deviation from regression (Sdi2).

S&P 500 Benefits

There are numerous reports related to the use of non-parametric methods in analyzing the GEI effect and selection of stable genotypes in different crops. For instance, Ahmadi et al. [46] used a set of non-parametric methods to investigate stability of grain and forage yields in 14 advanced lines of grass pea in semi-warm regions of Iran for three consecutive years. According to their results, among non-parametric parameters, the TOP parameter showed a dynamic concept of stability and showed a strong correlation with grain and forage yields. In a study conducted by Karimizadeh et al. [47], non-parametric statistic S(6) showed a dynamic concept of stability and well-recognized high-yielding and stable lentil genotypes in a MET experiment. Khalili and Pour-Aboughadareh [48] evaluated yield stability and adaptability of 40 barley doubled haploid lines in eight environments, reporting a dynamic concept of stability for TOP parameter. However, Sabaghnia et al. [49] reported a positive correlation between grain yield and NP(2), NP(3), and NP(4) stability parameters in durum wheat genotypes, and also showed a dynamic concept of stability for these measurements.

If a country is not politically stable, it is prone to having protests, riots, and even a full-out civil war in the worst situations. The main difference between MASV and ASV is the use of all significant IPCAs in the MASV statistic. Similar to ASV, a genotype with the lowest value of MASV will be selected as the most stable. In the race for the lowest of the low-cost index funds, this Fidelity fund made news by being among the first to charge no annual expenses. That means investors can keep all their cash invested for the long run. Below, we’re looking at some of the best index funds that track the S&P 500 and Nasdaq-100 indexes.

What Is the Most Political Stable Country?

When interest rates rise—and especially when bond yields are starting from very low levels—a bond fund’s total return can occasionally turn negative. That happens if the decline in bond prices is more than the yield the fund is earning. The stocks of companies in emerging markets have historically underperformed compared to U.S. stocks. Between 2014 and 2023, the Schwab emerging market funds had total returns of about 33% on a combined basis.

Burbano-Erazo et al. [65] used a set of AMMI-based methods to test the stability of common bean genotypes for heat and drought environments. They reported that the ASV and YSI parameters allow selecting stable genotypes across environments. Indeed, these parameters provided a measure of stability in a dynamic sense. The propensity to model the GEI led to the development of a series of methods and approaches called “stability analyses”, the concepts of which precede even analysis of variance (ANOVA) [5].

Furthermore, they were able to predict the genetic gain and accrue estimations of performance using the BLUP model. In a comparative study, Anuradha et al. [71] used a set of AMMI- and BLUP-based stability statistics to select stable and high-yielding finger millet genotypes. Based on the obtained results, they stated that several statistics, such as ASV, ASTAB, AVAMGE, DA, Dz, EV, and FA, proved that all have equal potential in the identification of stable genotypes.

R is identified as a free software environment for statistical computing and graphics. This software is compatible with a wide variety of Windows, MacOS, and UNIX platforms. Due to this advantage, many researchers and plant breeders have been encouraged to create scripts for computing stability statistics. Until now, there have many R scripts that each enable calculation of some stability parameters. However, Olivoto and Lucio [109] developed an R package “metan” for analyzing the GEI effect in plant breeding experiments. This package enables breeders to compute the AMMI model and GGE biplot, as well as estimating several parametric and non-parametric stability statistics.

The results obtained by this software will be graphically released [76]. Because of its methodology, very large stocks become more influential components of the index and tend to drown out or diminish the influence of this broad diversification.

Given the added cost of the insurance component in a stable value fund, the expense ratio may be higher than the cost of a comparable core bond fund. But if there’s a wide gap you need to decide if it’s worth the extra cost for the security a stable value fund provides. When looking to see if your 401(k) offers stable value funds, keep in mind that they come in a variety of names. Look for fund names that riff on terms such as principal preservation, capital accumulation or guaranteed income.

As a result, many people are curious about the political stability of certain countries. When we are talking about political stability, we are referring to whether a country is prone to civil unrest and whether the government is prone to being overthrown. We are also talking about countries that have a peaceful transition of power whenever an election takes place.

In the static concept, a specific stable genotype has a performance that is unaffected by the environmental conditions. Furthermore, this concept is analogous to the biological concept of stability such that the yield performance of a stable genotype has an environmental variance near to zero [6]. The dynamic concept states that a stable genotype has no deviation from predictable response to environments. In other words, the performance of a stable genotype is accordance with the estimated level or the prediction for each environment. Thus, the genotypic response to environmental conditions is not equal for all genotypes.

Based on this statistic, the genotypes that show higher values for this statistic are considered more stable. In the above equation, Xij is the grain yield of genotype ith in environment jth; X¯i. Is the grand mean; SSGE is the GEI sum square; and p and q are the numbers of genotypes and environments, respectively. Based on this statistic, the genotypes that show a lower value for 𝜃𝑖 are considered more stable. According to available data, the genetic improvements have accounted for 50% of the total gains in performance per unit area for major crops over the past seven decades.

In general, non-parametric stability parameters are easy to use and interpret. Furthermore, any deletions or additions of one or a few genotypes have no significant effects on the results. In this regard, if breeders are only interested in the existence of rank order differences across environments, these methods provide the best alternative to parametric models currently used. Hence, the relative comparisons of the tested genotypes are more important than absolute comparisons. As non-parametric methods are based on rank values, a target genotype is considered stable if it reveals a constant ranking pattern across different environments.

There are plenty of countries in the world that are considered politically stable, and most of them are located in the developed world. For example, Switzerland is generally called the most politically stable country on Earth. This is a country that takes a stance of isolationism whenever a conflict breaks out, and Switzerland was not even involved in World War 2. Furthermore, because it is so stable, it is widely considered to be the center of Europe’s economy. It was even major news when Switzerland broke with its long-standing policy of isolationism to condemn the Russian invasion of Ukraine, even though every other country in Europe, except Belarus, did so.

Four NP(1–4) statistics are a set of alternative non-parametric stability statistics defined by Thennarasu [33]. Indeed, these parameters are based on the ranks of adjusted means of the genotypes in each environment. This statistic was introduced by Kang [29] to select high-yielding and stable corn genotypes across various environments.

In other words, a large effect of the GEI results in smaller heritability; thus, progress from selection would be limited [8]. In METs, the best linear unbiased prediction (BLUP) is a useful model that will provide an ideal opportunity for the estimation of heritability across various environments [12,13]. Furthermore, this model provides additional information for the test of stability, adaptability, and simultaneous stability-adaptability in METs, which will be described in the following. Pour-Aboughadareh et al. [104] developed another free and user-friendly web-based software to compute several parametric and non-parametric stability statistics.

GENES is a software package used for data analysis and processing with different biometric models for genetic studies applied to plant and animal breeding. It allows parametric and non-parametric stability statistics to be computed and presents integration with MS Word, MS Excel and Paint. It is also compatible with the free software R and Matlab, through the supply of useful scripts available for complementary analyses in different areas [99].

As another non-parametric stability statistic, Fox et al. [30] suggested an ideal and simple parameter to superiority measure of general adaptability. This method is a stratified ranking approach that includes scoring the number of test environments in which each entry ranked in the LOW (bottom), MID (middle), and TOP (top) thirds of trial entries. The genotype that occurred mostly in the top third (high top value) was considered a widely adapted cultivar. The proportion of environments at which the genotype occurred in the each of these groups was determined to form the non-parametric measures of LOW, MID, and TOP, respectively.

In the above equations, N and K are the number of environments and genotypes, respectively. Like the other S&P 500 funds on this list, this fund gives exposure to 500 of the largest U.S. companies, which make up about 75% of the U.S. stock market’s total value.

Ultimately, though, how much of your bond allocation you might want to move into stable value funds is a matter of personal choice, based on your risk tolerance. If you really hate the idea of any price volatility, you might want to invest more of the fixed income portion of your portfolio in a stable value fund than in a core bond fund. Stable value funds typically invest in short-term US government bonds and high-quality corporate bonds. The duration for stable value funds is typically around three years or so. The longer a fund’s duration, the more sensitive it is to interest rate moves.
