When RSI 14 exceeds 70 (indicating overbought conditions), the average next-day return is 0.0200%. This occurred on 1,950 trading days in the dataset.

Coca-Cola stock delivered an impressive total cumulative return of 24,197.94% from 1980 to 2019. This means if you invested $100 in January 1980, it would have grown to approximately $24,298 by the end of 2019.

When RSI 14 falls below 30 (indicating oversold conditions), the average next-day return is 0.2294%. This occurred 944 times in your dataset, and 55.1% of those instances resulted in positive returns the following day.

The analysis shows how Bollinger Band Width (BB Width), a key volatility indicator, has evolved across different decades for Coca-Cola stock. The visualization displays both the average and median BB Width values for each decade, with error bars showing the standard deviation to illustrate the range of volatility within each period.

When MACD crosses above the signal line (bullish crossover), the average next-day return is 0.15%, compared to just 0.04% when MACD crosses below (bearish crossover). This means bullish crossovers outperform bearish ones by approximately 0.11 percentage points.

When the closing price is below the 200-day moving average, the average forward 1-day return is 0.0907%, compared to 0.0527% when above the MA 200. This represents a difference of 0.0381 percentage points in favor of being below the moving average.

The analysis compared average annual returns for Coca-Cola stock across four decades. The 1990s was the strongest performing decade with an average annual return of 24.68%, followed by the 1980s at 13.62%. The 2010s showed modest growth at 7.00%, while the 2000s was the weakest decade with an average annual return of -0.48%.

I've identified the 10 largest single-day percentage gains and losses in Coca-Cola's stock history. The analysis includes a horizontal bar chart showing all 20 extreme trading days, with gains displayed in green and losses in red, making it easy to compare the magnitude of these significant market movements.

Q4 (October-December) consistently delivers the best average returns across all years for Coca-Cola stock, with an average daily return of 0.1072%. This makes it the strongest performing quarter historically.

When the closing price touches the lower Bollinger Band, the next day's return averages 0.087% with a 53.3% chance of being positive. In contrast, when price touches the upper Bollinger Band, the next day's return averages only 0.029% with a 49.2% chance of being positive. This pattern suggests mean reversion behavior - prices tend to bounce back more strongly after touching the lower band.

The analysis identified 34 Golden Cross events where the 50-day moving average crossed above the 200-day moving average. A visualization was created showing the stock performance following these bullish signals, with returns tracked at 30, 60, and 90-day intervals after each crossing event.

The analysis reveals that Daily Range has virtually no predictive power for subsequent price movements. The correlation between Daily Range and next-day returns is -0.022, which is extremely weak and close to zero.

There is essentially no meaningful relationship between volume relative to its 20-day moving average and daily returns. The correlation coefficient is 0.0104, indicating a very weak positive relationship that is practically negligible.
