Commonwealth Bank: A Colossal Presence in the ASX
The Commonwealth Bank of Australia (ASX: CBA) has solidified its status as a giant in the Australian share market, commanding over 10% of the ASX by market capitalisation and outpacing other listed companies significantly. Recent research suggests that this dominance may not be as alarming as many investors perceive.
A Steady Ascent Over Three Decades
CBA’s journey to becoming an industry leader has unfolded over three decades. Its notable share price increase in the past year reflects a broader trend of gradual growth, reminiscent of mining titan BHP, which has consistently held a mega-cap position. Unlike transient leaders such as Telstra, News Corporation, or CSL—whose prominence was closely linked to specific trends—CBA’s sustained success has shown resilience through diverse economic challenges.
Historical Market Concentration
Concerns about the concentration of market power are not new. UBS analyses indicate that Australia’s stock market has historically experienced similar dominance by a single entity, as evidenced by previous peaks held by Telstra in 1999, News Corp in 2000, BHP in 2009, and CSL in 2020. Notably, these occurrences are evenly spread between market peaks and troughs, illustrating no clear correlation with market conditions during these pivotal moments.
The Misconception of Easier Stock Selection
A common belief among investors is that identifying strong stocks becomes easier once a market leader’s influence wanes. However, data refutes this theory, demonstrating no patterned improvement in stock selection post-leader decline. Additionally, the assumption that foreign investors cause peak valuations only to subsequently withdraw lacks robust evidence, as investment flows from abroad showed no significant declines during these highs.
Observations from Market Trends
An important revelation from historical trends is the impact on sector peers when a dominant player falters. Typically, companies within the same sector suffer alongside the declining leader. For instance, after News Corp’s devaluation in 2000, other media stocks experienced severe downturns, as did peers in healthcare following a peak decline in CSL in March 2020. This trend underscores that issues affecting a market leader can equally cascade through its sector, suggesting that seeking refuge in similar entities may prove futile.
Implications for Banking Sector
This pattern holds substantial implications for Australia’s banking sector. Analysts at UBS point out that all major banks currently appear overvalued, dissuading investors from making sector-specific rotations. Should CBA experience a downturn, it is likely that other banks will follow suit, as the underlying triggers are often sector-wide rather than isolated incidents.
Seeking Alternatives
Investors worried about CBA’s stronghold might consider diversifying outside the banking sector. UBS suggests that large-cap healthcare stocks may offer a viable alternative, with appealing valuations and growth potential drawing investment interest.
Conclusion
In essence, when market leaders falter, the repercussions frequently extend throughout their sectors, reinforcing the notion that strategic investment across different sectors is crucial during such periods. Investors should recognise that trying to pivot within a declining industry might lead to increased losses, advocating instead for broader diversification to navigate market uncertainties effectively.
