[INVX] Post-Earnings Announcement DriftWhat does this strategy do?
This Pine Script strategy implements the Post-earnings announcement drift (PEAD) strategy, which is a financial market anomaly where a stock's price tends to drift in the direction of the firm's earnings surprise for an extended period of time.
Ref: en.wikipedia.org
An earnings announcement is an official public statement of a company's profitability for a specific time period, typically a quarter or a year. It includes various financial metrics but the most watched figure is the Earnings Per Share (EPS). Analysts estimate the EPS before the announcement, and the actual EPS is compared to this estimate to determine if there was an earnings surprise.
An earnings surprise occurs when the actual EPS is significantly different from the analysts' estimates. A positive earnings surprise indicates that the actual EPS is higher than the estimate, while a negative earnings surprise suggests the EPS is lower than anticipated.
The script takes the following inputs
" Holding periods (bar) " : This input defines the number of periods (or bars) the script will hold a position after the earnings announcement.
" Surprise threshold (%) ": This input sets the minimum percentage for an earnings surprise, which triggers the strategy to enter either a long or short position. In essence, it represents the minimum deviation between the estimated and actual Earnings Per Share (EPS) that will trigger a trade. A higher threshold may lead to fewer, potentially more significant trades, while a lower threshold might result in more frequent, possibly less impactful trades. This parameter allows you to adjust the sensitivity of the strategy to earnings surprises.
Positive earnings surprise
After the earnings announcement, the script compares the actual EPS with the estimated EPS to identify an earnings surprise. If there is a positive earnings surprise, the script will enter a long position. A long position is a bullish strategy where the investor expects the stock price to rise.
Negative earnings surprise
On the other hand, if there is a negative earnings surprise, the script will enter a short position. A short position is a bearish strategy where the investor expects the stock price to fall.
In both scenarios, the position (either long or short) is held for the number of periods specified in the "Holding periods (bar)" input. This strategy is based on the assumption that the stock price will continue to drift in the direction of the earnings surprise for the specified holding period.
