This month, the top trades were strongly led by the Smartshares US 500 ETF (NZX: USF), followed by Microsoft (NASDAQ: MSFT) and NVIDIA (NASDAQ: NVDA). It was a strong month for ETF trading overall, with 9 of the top 20 trades consisting of ETFs. US tech stocks were also a particular focus for New Zealand investors over the period.
It should be noted that the assets in our trading snapshots are ordered by the number of Sharesight users trading that asset, while the size of the bars indicate the actual trade volume. So while there were more customers trading in MSFT, the volume of NVDA trades was higher, meaning that while there were fewer people trading in NVDA compared to MSFT, they made more trades.
