Does money market pay out per-diem interests?

Yes, and no. Or should I say "not really".

During the month the interest is built in to the share price of the shares. If you watched it daily you would see the value of your MM goes up during the month and when the interest is "paid" if it was reinvested that by itself doesn't change the total value.

For example, if your fund earned 1% a month and it was worth $1.00 at the start of the month, by the end of the month the day before the interest payment, it would be worth $1.01 a share then pay $0.01 or 1% and the share price would fall back to $1.00 a share. But you would still have $1.01 total.

During the month, half way, the share prices might be $1.00.5 times the number of shares. Since it is a fraction you don't see it in the share price but it is represented in the total value of your holdings.

The same is not true for savings accounts or CDs. Some pro rate the interest, most don't. CDs have a specific start date and you are not putting money in and taking it out all the time. To prevent that CDs have a penalty for withdrawing early. Savings account you might and they would use the "average" total to figure interest once a month.

With mutual funds it has to be that way or I could buy just before the interest is paid and sell the next day picking up 1% in two days, not 30 days, or 15 times what it really earns. They would go broke doing that.

And I would get more interest than I was entitled if I was putting in any money during the month. So the interest is figured every day in to the share price but paid out only once a month.

Nursing is a very demanding, hands-on, minds - on, hard-working career, but it can also be a very rewarding career for the right person. I cannot decide whether or not nursing would be right for you, but by looking at your post, you said you are considering it because of the pay and the job stability. Let me tell you from experience - the people I know that have gone into nursing (or any other career for that matter) with those reasons alone usually don't make it out happy. They are the ones that suffer from burn-out, unnecessary stress and unhappiness because they are doing something they really don't want to do. I would suggest you shadow a nurses job from day-to-day. If you're not wanting to work weekends, holidays, and nights - that limits your possibilities as a nurse, however there are so many opportunities in this field. Investigate and search for yourself whether or not this career is something that suits you well. It's only up to you!
