Hypothesis

Stocks with positive price momentum experience smaller post-ex-date price declines during dividend capture.

The theory is that existing buying pressure (evidenced by momentum indicators) partially offsets the dividend gap when a stock goes ex-dividend. We test this by comparing a control group (all eligible dividends) against filtered groups that only enter positions in stocks showing positive momentum.

What's Wrong With This Experiment

Use With Caution

Results are directionally useful but missing 2 planned variants. Use with caution for real trading decisions.

Medium

Missing ADX/MACD Indicators

Variants B (Strong Uptrend) and C (Combined Momentum) could not be tested due to missing ADX and MACD data in the indicators table.

Impact: Only 3 of the planned 5 variants are included in results.

Medium

Declaration Date Coverage

Only 70.5% of dividends have declaration dates. Trades without declaration dates are excluded to prevent look-ahead bias.

Impact: Trade universe reduced by ~30%.

Info

Indicator Timing

Technical indicators are taken from the day BEFORE entry date. This assumes end-of-day decision making.

Info

Transaction Costs

No transaction costs applied in this version. Real trading would incur ~0.10-0.20% round-trip costs.

Note: These issues have been identified through post-hoc audit. Future experiments will address these problems through improved data validation, stricter look-ahead bias checks, and better methodology. This experiment (v1.0) will not be re-run but serves as a learning reference.

Total: 10,290 trades | $7,441 dividends captured
