All the advice around S&P 500 index funds have always been ignore the news, forget about the headlines, and put your money in an index fund and forget about as they always go up in the long run. But when you look at recent news like 7 companies dominating the value of S&P500 so the market being more susceptible to a crash, plus all the crazy geopolitical posturing happening, is an index fund of S&P 500 still considered a long term safety option?
Also noting that nothing is predictable when it comes to the markets, and all we are doing is guessing based on the past, but just curious to see what are the general thoughts around this?
