Yes, I agree. That is my understanding. With stocks you will face substantial risk, especially if you have done no reading. You should start reading and then ask specific questions.
Stocks are risky. If you don't know what you are doing, you could lose a lot of money in a short period of time.
Even if you know what you are doing, your stocks may drop in value in the short term, and they may not be high enough for you to sell at a profit. You may need to hold for the long term.
Again, start reading all you can. Try
