Bitcoin is booming again - up roughly 20% this week and back above $76K. Can it be useful to equity investors even if they never intend to hold it directly?

Our latest QuantConnect research examines whether Bitcoin can serve as a real-time indicator of market risk appetite. The strategy uses Bitcoin’s trend and momentum to determine when to hold QQQ and when to rotate into SHY.

When Bitcoin is above its 50-day moving average and has positive 20-day momentum, the strategy holds QQQ. When those conditions are not met, it moves into SHY.

The hypothesis is that Bitcoin’s continuous trading and highly responsive market structure may allow changes in global risk appetite to appear there before they are fully reflected in growth equities.

That relationship is particularly interesting during the current strength in Bitcoin prices. If Bitcoin is capturing a broader shift toward risk-taking, its price behavior may provide useful information for systematic equity allocation.

From 2014 to 2026, the strategy produced a Sharpe ratio of 0.838, beating 0.682 for buy-and-hold QQQ and 0.564 for SPY.

What if momentum works better in stocks that don't pay dividends?

We tested the idea.

Buy the strongest-momentum stocks among liquid US companies that pay no dividends, then rebalance monthly.

With a 10-year backtest: 📈 Sharpe: 0.602, beating the benchmarks with almost all parameter combinations 💪. A surprisingly simple behavioral-finance signal.

What if the VIX could tell you when to short volatility... and when to get out? 👀

This dual-signal strategy uses VIX + VIX3M to switch between short and long VIXY exposure.

Result: 0.729 Sharpe vs 0.582 for SPY.

Can algorithmic execution reveal a return signal?

This strategy ranks liquid US equities by intraday volume periodicity, then weights them by confirmed execution flow.

Sharpe: 0.792 vs. 0.406 for SPY. All 25 parameter tests beat the benchmark.

New Friday Research Drop!🎉 🔬 💹 Read: https://t.co/XOEYtJ5xNl

In this study, we build a long-short momentum strategy with conditional short legs to improve the performance and reliability.

The objective is to preserve the strength of long-only portfolio momentum, without continually paying for short assets that may rebound.

Using asset correlations, we can exclude any hard-coded regime parameters, indicating true divergence among the short candidates.

From July 2007 through June 2026, the conditional hedge increased the strategy’s Sharpe ratio from 0.451 to 0.498, compared with 0.407 for SPY. The result was also relatively stable: 24 of the 25 correlation-window combinations tested outperformed the benchmark’s Sharpe ratio.

Can changes in filing language predict returns?

The team @ Triton Quantitative Trading tested a strategy that selects liquid US stocks with the most stable filing language.

The result was a modest improvement in risk-adjusted returns for those companies that make _fewer_ changes to their filings.

New Friday Research Drop!🧪🔬🎉

Community member, Zhaoren Deng, explored a classic options concept applied dynamically to the Magnificent 7 - conversion arbitrage.

Conversion combines a long stock position, a long put, and a short call at the same strike and expiry. In theory, the package behaves like a fixed-payoff instrument, with returns driven by deviations from put-call parity.

New Friday research drop from the QuantConnect team!🎉🧪🔬

This week, we explored the MAX Effect: how a simple empirical observation can be translated into a practical, systematic strategy.

Check it out: https://t.co/EXNlFr4Jr7

Building on earlier work, this QuantConnect study explores using VIX-based leverage scaling to adjust market exposure across volatility regimes.

The research shows that stocks with extreme positive daily returns can behave differently in subsequent periods, creating a measurable anomaly in expected returns.

We extend that intuition into a dynamic portfolio approach: instead of treating leverage as fixed, exposure adapts to changing market stress. The result is a clean example of how volatility signals can support risk management and portfolio construction.

This strategy was also almost entirely implemented by our new agentic Research Pipeline. We fed the research paper into the AI, which expanded the idea, backtested it, tested parameter sensitivity, and helped draft the first version of the research post ✨
