Just when you thought our stock market had had a shocker for 2026, we have seen the S&P/ASX 200 spike by 6%, so it begs the question: how come? US stock market indexes have been hit by AI anxiety and doubts about overinvestment in this new age innovation that promises much. And that should send stocks up, which will not only justify the recent rise in local stocks but give momentum for further rises. It is up 7.9% over the month, but only 1.38% over the week, as the local stock market has surged. This could really help ETFs that focus on the top 200 stocks such as VAS, A200, STW and IOZ.
