You could try saying something to him like "I know that I don't understand as much about stocks and stuff as you do, but this stuff is important to me. For one thing, it affects our future. For another, it's important to you, and that makes it important to to me. I know I don't understand a lot of it, but you know so much about it I bet if you explained it to me it would help me get it a lot better."
If he's concerned and isn't telling you because he doesn't want to worry you, then you can say something to him like "Sweetheart, I know you don't want to talk about it and worry me, but the thing is, I can see it bothers you, and that worries me, so I'm already worried. Wouldn't it be better if we were both able to worry about the same thing, and be able to support each other through it? I know it would make me feel better, even if I can't fix it, it would help knowing what's going on in your life."
