The Short and Long-Run Performance of Sharia-Compliant Initial Public Offerings (IPOs) in the Emerging Market: Evidence from the Saudi Arabia Share Market
Bibliographic record
Abstract
This study examines the short-and long-run share performance of 40 Sharia-compliant IPO companies listed on the Saudi Arabia Stock Exchange (Tadawul) from 1 st January 2000 to 31 st August 2017.This study employs both market-adjusted initial returns and buy-and-hold abnormal return to measure the share performance of IPOs.First, the analysis shows that Sharia-compliant IPOs are underpricing with abnormal initial returns of 79.23%.Second, the results suggest that investors could earn positive and significant market-adjusted BHAR of 14.67% if they held IPO shares over the eighteen-month period following the listing date when EWI is used as a market benchmark.This study also finds that IPO companies outperformed the VWI although the results are insignificant.The findings on the long-run overperformance contribute to the IPO literature on long-run performance of Sharia-compliant IPOs.The present study would benefit foreign investors and market regulators who are trying to understand the market behaviour in an emerging market.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
