When you invest, it implies that you are investing your own money, but you can invest someone else's. For example, you might say "I invested my parents' money in bonds". If you were to say "I invested in bonds", then it is always your own money. However, sometimes, for clarity, you might want to stress that it was your own money. In that case, "I invested my money in stocks" would be fine. In fact, it is more likely that when you use this sentence, it is in response to someone asking about your money:

A: What did you do with your savings?
B: I invested all of it in stocks.

Or like this:

A: I invest in bonds. What do you do with your money?
B: Me? I invest my money in stocks and foreign exchange.

Or it could not even be a question:

A: I invest my money in shares.
B: Really? I invest my money in bonds.

I hope that makes it clear.
