Formal Letter to Investment Analyst

Dear investment analyst

My friend told me, that you are very good specialist in investments, thats why I decide to write you. I have some free money, which I want to invest in stocks and shares, but I now that it is quite risky.
I found big, successful but quite new company. Now it is very popular, but I am afraide that after some years it can bankrupt, because in the early years, many businesses fail. In this situation my shares could become worthless and I will lose all my money. How can I understand that this company will be successful in the future?…
