Did Dr Reddy’s Share Price Really Fall by 80%? Understanding the Stock Split and F&O Adjustments

Dr Reddy’s Stock Split Explained: Why Share Price Dropped by 79.6%

Against a previous close of Rs 6,514.15 on October 25, Dr Reddy’s Laboratories Ltd.’s share price opened on Monday at Rs 1,328.90, showing an apparent drop of 79.6%. This drop isn’t a sign of lost value but rather the result of a stock split that adjusted each share’s face value from Rs 5 to Rs 1. Here’s how this split affects both the share price and the Futures & Options (F&O) contracts associated with it.

What is a Stock Split, and Why Do Companies Do It?

In a stock split, each existing share is divided into smaller shares, each with a lower face value. For Dr Reddy’s, each Rs 5 share is split into five shares with a face value of Rs 1, which explains the sharp fall in share price seen on the market. This move is aimed at enhancing liquidity and making shares more accessible to a broader range of investors.

Impact of Stock Split on Trading Apps

The sudden price drop shown in some trading apps led to confusion, as some apps displayed the old pre-split price of Dr Reddy’s share price, suggesting a steep fall. Adjusted for the stock split, the share price actually remained stable, trading at around Rs 1,316.90, up by 1.04% on the NSE.

Key Adjustments for Derivative Market Traders

For traders holding F&O positions in Dr Reddy’s, the stock split requires specific adjustments to ensure that contracts reflect the new share structure without altering their value. Here’s what has been adjusted:

Futures Contracts

1. Positions: All open positions have been multiplied by an adjustment factor of 5.
2. Price: The futures price was divided by 5, keeping the contract’s value balanced after the split.
3. Carry Forward Value: Positions are carried forward based on the last settlement price before the split date.

Options Contracts

1. Strike Price: Pre-split strike prices were divided by 5.
2. Positions: Existing options positions were adjusted by multiplying the lot size by 5, aligning with the new share count.

Important Dates: When the Adjustments Take Effect

The Ex-Date for this corporate action was October 28, 2024. From this date, all adjustments in F&O contracts were implemented, meaning all derivative positions in Dr Reddy’s now align with the new share structure.

Practical Example: What this Means for Traders

Consider a call option with a strike price of Rs 6,600 before the split. After the adjustment, the strike price is now set to Rs 1,320, and the contract lot size has increased fivefold. This ensures that the overall value remains intact despite the structural change in share price.
