C²I combines corporate insider trading disclosures with congressional stock transaction reports to surface stocks worth investigating—and rigorously test whether those signals outperform the market.

01 / Our investment thesis

Why these signals might matter

Executives can choose to purchase shares using their own capital, and congressional investment disclosures can provide a second independent lens. We research whether meaningful buying activity precedes future stock gains. We do not assume insiders always predict stock performance.

SIGNAL 01

Executive conviction

Open-market purchases by a CEO or CFO may indicate a belief that shares are undervalued. We distinguish discretionary purchases from grants, tax withholding and option exercises.

SIGNAL 02

Buying clusters

Purchases by several independent officers and directors can be more informative than an isolated transaction. We test this assumption rather than treating it as proven.

SIGNAL 03

Congressional agreement

Newly disclosed purchases by legislators may corroborate a signal—but late filing dates, broad value ranges and contrary evidence can substantially weaken usefulness.

Our proposed scoring framework · not yet calibrated
C²I = 55% insider buying + 15% buying clusters + 15% congressional activity + 15% agreement
Insider buying · 55%Clusters · 15%Congress · 15%Agreement · 15%

A separate investment-quality review considers valuation, financial health, earnings events, liquidity and downside risk. These initial weights are hypotheses, not verified predictors.

Why we're cautiously optimistic: Prior academic research has found that some categories of corporate insider purchases contain useful information, particularly when separating voluntary buying from other transactions. But abnormal returns vary across samples, and congressional copying strategies have not consistently outperformed the market. C²I needs its own point-in-time backtest before claiming a demonstrated edge.

04 / Accountability

Results, not hype

We will track each candidate from the next practicable trading session after its signal is publicly disclosed and compare holding-period returns with SPY. This prevents using future information to make a historical strategy look more successful than it was.

Research status: No validated C²I win rate or excess-return backtest has been published. The initial positions are research candidates, not an audited model portfolio. Returns will be posted only when the necessary starting prices and subsequent history are verified.

How we will judge success

For each horizon: percentage of winners, average and median total return, average excess return relative to SPY, drawdowns, the impact of spreads and costs, and performance of insider-only versus Congress-only versus combined signals. We also count losing selections and delisted stocks.

05 / Transparency

Primary sources

The filing date is critical: a trade can occur well before it is publicly known. Most SEC Form 4 transactions are due within two business days, while covered congressional trades are generally reported within 30 days of notification and no later than 45 days after the trade.

Important caveats: disclosures may be amended; some congressional transactions belong to spouses or dependents; reported amounts may be broad ranges; insider sales frequently have non-informational reasons. Public disclosures do not establish illegal insider trading or misconduct.
