Out of interest, is that better or worse than you were expecting? You don't say when in 2013 you started, but since the start of the year the S&P is up around 6%, the NASDAQ composite is up 4.5%, and the FTSE All Share is up a similar amount.

Assuming you did put the money in in January you would have probably made more profit by simply investing in an index tracker.

True, I'm losing to the market, since January. But 'the market' is unpredictable, unrealized gains on paper. Unless you sell your index tracking positions, you will, in the next couple years, see some nice unrealized losses on paper.

My gains are realized. And fairly predictable.

Also, I only have about $55k in capital. But my rapid buy/sell cycle (not HFT) allows me to keep 'reusing' it.

So you're up 5% on capital employed. Well, if you can sustain that, you'll be doing pretty well!
