The Australian market has recently experienced a remarkable trading run, with the ASX hitting all-time highs despite some geopolitical tensions. As traders anticipate potential interest rate cuts and key speeches that could influence market dynamics, attention is also turning to smaller investment opportunities. Penny stocks, though an older term, continue to capture interest due to their affordability and growth potential; they often represent newer companies with strong financials that can lead to significant returns.
