At the start of every trading day, it can be useful to know which stocks are humming out of the gate.

Large percentage moves in small caps aren’t uncommon, but sometimes a big announcement can cause a stock to rocket higher (or fall).

Stockhead’s Top 10 at 10 highlights the best (and worst) performing ASX small caps in morning trade.

The market opens at 10am (eastern time) and the data is taken at 10:15am, once every stock has commenced trading.

Stocks highlighted in yellow have made potentially market-moving announcements:
