Invest in a global tracker in that case is some option. I do prefer to choose most of the direction rather then just use one tracker but I wouldn't stick to just one country if you can avoid it.
Ideally the stocks of a country should be linked to the world market but its not always the case, the ideal would be in giving you some diversity away from just your national economy.
Unfortunately Trump is making things harder for those he deems not friendly when all that might be true is they are merely not close which is hardly fair. The only positive I can be sure of is this is not a beneficial policy for either party buyer or seller and it will not last beyond this term of office imo.
Mostly people don't know the idea of diversification because they have no financial knowledge which starts from the home and they are from poor families as there are many poor people in our society and they are spreading negativity about the money and investment. Rich people always try to earn money from different resources and investment because they have mindset of rich people and these kind of people could not be poor at any time when any unexpected situation happens. People have to work on their knowledge to do investment on different platforms which is not an easy task .Diversification is best topic for the people who want to become a wealthy person of their family but at the same time, that is not easy.
Financial self-improvement is crucial. Some people acquire this knowledge from their families, others from school and their surroundings. A mindset often guides individuals and provides an advantage in how they make decisions. Diversification requires knowledge in many areas. Diversifying without prior knowledge is a mistake, as there are many investment instruments available, and making sound decisions becomes difficult without understanding what to invest in.
Every investment carries risks, so when diversifying, you should carefully analyze these risks and plan for these risks.
