I recently started investing in the stock market. I initially started with the idea that I'd invest in 5 diversified ETF's or Index Funds and just let it sit . . . . .the idea being I wouldn't incur any tax penalties for a few years. I got tired of waiting for those funds to get moving, so I sold those shares and am now invested in ~15 fairly diversified stocks and have been actively trading for profit (and losses, of course). If things continue the way they are, I will hopefully have a nice profit . . . I'm just concerned that taxes are going to kill me. In the books I've read, there are two prominant themes: 1) Taxes + Fund Expenses + Trading Commissions will erode any profits you may have made trading. Just stay invested in a few diversified index funds and rebalance once per year. or 2) If you're paying taxes, it's because you're making money. It's not a bad thing to have to pay taxes. Trade away. Any thoughts/advice? Any good books on stock trading and taxes?
