What a week for ASX shares!

The S&P/ASX All Ordinaries Index (ASX: XAO) has been on a rollercoaster this week.

On Monday, we saw the biggest fall of the week at 4.12%. On Tuesday, we saw a 2.39% rebound.

Then Wednesday brought another dip of 1.85%. Yesterday, the market went up again, with ASX All Ords shares ripping 4.66% higher.

Today, we are back in the dip, down 1.28% at the time of writing.

All of this turmoil has been caused by the US reciprocal tariffs announced on 3 April, and the about-face on them this week.

US President Donald Trump announced a 90-day reprieve for every nation except China.

For the next 90 days, trading partners will be subject to the baseline 10% tariff only rather than the much higher individualised tariffs.

Upon last check, the US tariff on China is now 145%. But that could change in a nano-second, such is the President's unpredictability.

All of this has sent the markets into a spin, presenting buying opportunities galore for those investors brave enough to buy the dip.

New data from online trading platform Stake provides an insight into which ASX shares Aussie investors have been targeting during the market sell-off.

Investors buying the dip target ASX blue-chip shares

Stake's markets analyst Samy Sriram said Aussie investors buying the dip on Monday gravitated to ASX 200 large-cap shares.

Sriram said:

On Stake Aus, positioning has been largely geared towards banks and miners.

With the recent market volatility and uncertainty around US trade policy dominating markets, investors have been adding exposure to large caps and steering clear of the smaller end of the market.

Weakening commodity prices also encouraged investors to target ASX mining shares.

Sriram commented:

Stocks like BHP and Fortescue saw big declines in light of copper and iron ore prices declining significantly Monday, but a significant proportion of retail investors on Stake saw this as an opportunity to buy the dip in these miners.
