It was a difficult month for Aussie investors, with the S&P/ASX 200 Index (ASX: XJO) crashing 3% during the period.
Unfortunately, that decline wasn't anywhere near as bad as what some ASX 200 shares recorded. Here's why these shares fell 10% or more during November:
Bendigo and Adelaide Bank Ltd (ASX: BEN)
The Bendigo and Adelaide Bank share price was down 19.1% in November. This reflects weakness in the banking sector after the release of the results of an investigation by Deloitte into suspicious activity. The investigation, which was initiated by the bank, concluded that deficiencies existed regarding the bank's approach to the identification, mitigation and management of money laundering (ML) and terrorism financing (TF) risk. The bank stated: "The Board is very disappointed with the findings and is fully committed to ensuring that the Bank undertakes the necessary enhancements to its systems, processes and frameworks to ensure it is fully compliant with its obligations." In addition, the release of a disappointing first quarter update weighed on investor sentiment.
Commonwealth Bank of Australia (ASX: CBA)
The CBA share price lost 11.2% of its value during the month. This was driven by the release of its first quarter result. CBA reported operating income growth of 3% and a 1% lift in cash net profit after tax to $2.6 billion. While not a bad result, it just wasn't enough to justify its premium valuation. CBA's CEO, Matt Comyn, also spoke cautiously about its outlook. He said: "We are closely watching the increased competitive intensity and implications across the financial system, and we will continue to adjust our settings as appropriate. The Australian economy remains resilient. Economic growth is recovering and disposable income is rising for many households. We remain focused on our strategy to build a brighter future for all."
DroneShield Ltd (ASX: DRO)
The DroneShield share price had a month to forget in November and crashed 48.3% lower. The catalyst for this was news that insiders sold down their holdings. This includes its CEO, Oleg Vornik, who offloaded approximately 14.8 million shares through an on-market trade for a total consideration of $49.5 million. But it is worth remembering that he retains a significant amount of vested and unvested equity in the business. As a result, it is fair to say that his interests remain firmly aligned with shareholders.
TechnologyOne Ltd (ASX: TNE)
The TechnologyOne share price was a poor performer and sank 18.4% last month. This was despite the enterprise software company delivering another record full year result for FY 2025. In fact, TechnologyOne outperformed its guidance, announced a special dividend, and reiterated its 2030 $1 billion+ annualised recurring revenue (ARR) target. However, it seems that some investors were expecting even stronger ARR growth for the 12 months and were quick to hit the sell button.
