PEAK6 Investments, L.P.'s disclosed holdings carry a Herfindahl concentration index of 0.014 — mathematically equivalent to about 71 equally-sized positions, well below its 4219 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 5.20), with a handful of outsized bets alongside many smaller positions.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
Sector classification currently covers about 51% of this portfolio's disclosed value; the remainder includes holdings (e.g. unmapped tickers, options, or other security types) not yet covered by our sector mapping.

PEAK6 is doubling down on the most liquid, high-momentum US mega-cap growth stories — Amazon alone jumps to 9% — while simultaneously trimming its Chinese tech exposure and adding a small Russell 2000 ETF. This signals a conviction that domestic tech supremacy will accelerate, with the small-cap bet a mere tactical tail hedge rather than a conviction pivot.
These flows are pricing in a late-cycle regime where US consumer and tech growth remain robust enough to justify expanding multiples, with a subtle hedge that small caps may finally catch up. The opposing thesis is that momentum is already exhausted, consensus is too crowded in FAANG, and the Fed’s tightening or a trade war disruption will compress multiples, particularly as Chinese exposure is explicitly reduced.
Despite holding 1,989 positions, PEAK6’s effective portfolio is driven by a handful of massive bets (AMZN alone is ~9% of the portfolio), creating a hidden concentration risk. A drawdown in these core holdings will overwhelm the diversification benefit from the hundreds of tiny positions, amplifying losses due to correlations tightening in a downturn.
