It's occurred to me that I don't nearly have as much money to invest as I once did. That, and I've become real skittish regarding the stock market. Anyhow, my transaction fee is $7.00 per trade. What's a reasonable minimum amount to be spent on a trade and still get value as per the $7.00 transaction fee? (e.g. does it make sense to make a $300 trade if the transaction fee is $7.00)?
