Tech stocks had a decent day — the Nasdaq-style indices climbed over a percent — but the broader portfolio slipped slightly, as several of the experiment's strategies were either betting against the market or caught on the wrong side of a choppy session.

The dip-buyers continued to be the stars of the experiment. The version that learns and adjusts over time is up nearly 20% overall, and today it locked in a solid gain on a name it had been patiently holding. The cautious, frozen-in-place dip-buyer also quietly closed a winning trade. On the other side, the agent that bets against markets — shorting things it expects to fall — is having a rough go of it; a rising market is its natural enemy, and that's mostly what it's faced. The strategy built around gold and silver ratios remains the portfolio's deepest hole. Meanwhile, the hyperactive day-trader churned through a dozen positions and came out slightly ahead, which is about as good as that approach tends to do.

All told, a mildly frustrating day for the collective — the market moved up, but the portfolio didn't fully come along for the ride.
