Abstract:
activities and macroeconomic factors in Sri Lanka.
Design/methodology/approach– This study uses principal component analysis (PCA) and
autoregressive distributed lag (ARDL) techniques to examine the relationship between IPO activities and
macroeconomic factors. Ten macroeconomic variables are transformed into principal components (factors)
using PCA. Then, ARDLisapplied to investigate the long- and short-term relationships between IPO activities
and the transformed macroeconomic factors.
Findings– Theempirical investigation identifies three principal factors from the ten macroeconomic variables,
of which twofactors have a significant long-run association with IPO activities: “return on investment (RTOI)”
and “economic and market development (ECMD).” In the short run, “trade openness and banking sector
development (TOBD)” and RTOI are significantly associated with IPO activities.
Research limitations/implications– The study was based on 30 years of observations, which passed all
diagnostic tests but may be insufficient for generalizing the findings. Future studies could use high-frequency
data (monthly or quarterly) to increase the number of observations and repeat the method and analysis. Also,

Practical implications– The study highlights the importance of considering both long- and short-term
associations when analyzing the impact of macroeconomic variables on IPO activities.
Originality/value– This study is the first to comprehensively examine the relationship between IPO activities
and macroeconomic variables using PCA and the ARDL technique. The study provides insight into the
macroeconomic factors that influence IPO activities in Sri Lanka and highlights the importance of considering
long- and short-term associations.
