Algorithmic trading systems – whether they are executed by computer programs or used as decision support tools by disciplined individuals – have been shown to significantly outperform traditional methods of investing. (1,2) Take, for example, that algorithmic trading programs do not hold onto losing trades nor do they hold winning trades until they move adversely. When trading volatile markets, intra-day, computers have a decided advantage in response time. But in the realm of algorithmic investing and longer horizons, it will be knowledge-based investors whose decisions are supported by machine algorithms that possess the key to superior returns. (3)
Buy-sell decisions essentially reflect the cognitive ability of investors to make rational decisions about timing and position size. But such decisions are multifaceted, requiring integration of algorithmic trade signals and risk-reward calculations while continuously self-regulating emotions and cognition. Taken together, one’s ability to succeed in this complex environment relies upon three things: (1) good models, (2) quantitative decision support tools, and (3) keen attentional skills and self-awareness.
Empirical Tools for Side-stepping Drawdowns
Ultimately, the only way to avoid drawdowns is to forecast them and then evade them. To mitigate unfavorable return distributions, nextSignals synthesizes data from multiple sources:
- asymmetric depth in out-of-the money options and composite gamma exposure as a primary measure of information content [4,5,6,7,8,9],
- significant changes in FINRA short sale trade data [10,11],
- inversion in VIX futures term structure [12,13,14], and
- descriptive statistics that measure volatility clustering (e.g. GJR-GARCH ) for predicting one-day ahead returns in aggregate indexes [15,16].
A Beta Rotation Algo
Close to 90% of investment returns are determined by portfolio asset allocation. nextSignals’ principle strategy amounts to a regime-switching asset allocation model, moving from risk-free assets and defensive equities during periods of high variance to momentum stocks during low variance states.
Combining momentum with defensive signaling through relative performance has been effectively applied to asset allocation and risk positioning.  But even the most sophisticated machine code is unable to collect and interpret multiple anticipatory signals ahead of an imminent selloff.
nextSignals‘ original investment algorithm was based on a momentum strategy shown to consistently outperform when the investing environment is more favorable towards higher-beta sectors with a high positive correlation to the S&P 500 Index. Otherwise, the algorithm rotates into lower-beta sectors with a low correlation to the S&P 500 Index. While capable of outperforming the usual market benchmarks, drawdowns dogged performance potential. A simple method was needed to preserve the performance of beta rotation while temporarily moving to a safe haven (e.g. US Treasuries, Japanese Yen, or gold) when indicated.
Crash Protection through Anticipatory Signaling
Consistent with the work of Gerd Gigerenzer, Director of Risk Literacy and the Max Planck Institute of Human Development, nextSignals has created “fast and frugal trees” – heuristics built on a few key metrics. Take, for example, the coincident selling by dark pools (DIX) and contraction in long gamma positioning (GEX) that nextSignals has found appear at market highs prior to significant retrenchments. In fact, when asset allocation in the beta rotation algo (above) switches to US Treasuries when DIX-GEX signaling appears, the algorithm’s performance improves substantially and drawdowns are largely be averted.
