S&P 500 could be seen as an ideal risk averse investment, especially to novice investors, because of its nature.
Risk averse means that an investor prefers to take less risk to avoid high exposure to price movements or leverage, and as a result expects lower returns.
Because the S&P 500 include hundreds of stocks from different sectors and industries, the huge risk associated with individual stock volatility is eliminated.
S&P 500 is also seen as a steady long term investment because of the highly ranked nature of the companies selected, ones that are long term performers not only in steady stock capital gains, but also their impact on the society and economy as a whole.
Individual low performing equities, in variables such as stock price movements or low reported earnings, generally have low impact in the overall performance of the SPX index due to its diversification in assets.
Conclusively, SPX index covers most of the market risk involved in the trading of stock equities, as such S&P 500 index sums up to be a highly ranked buy and hold investment.
