As most investors would be acutely aware, the past six weeks or so have been an exceptionally volatile time for investors. Between 14 February and 13 March, the S&P/ASX 200 Index (ASX: XJO) dropped by a painful 9.4%. Over in the United States, the S&P 500 had a similar experience, led by the big tech stocks.
Yep, between 19 February and 13 March, the S&P 500 fell by 10.13%.
Over in the US, the big tech stocks like Apple, Microsoft, NVIDIA, Tesla and Amazon command the largest weighting on the stock market, just as the big four banks do here on the ASX.
Given this fall in the S&P 500, it will come as no surprise to hear that the 'magnificent seven' tech stocks had a rather nasty few weeks, too. For example, Apple stock tanked by more than 15% between 25 February and 13 March. Nvidia fared even worse, crashing 24% between 20 February and 10 March.
Over a similar period, Tesla shares plunged more than 38%, although there were probably other factors at play there.
More recent weeks have been kinder to some of the big tech stocks over the States.
But whether we have truly found a bottom and turned a corner remains to be seen. After all, we are set for a fairly dramatic week on global markets this week with President Donald Trump's tariff 'liberation day' fast approaching.
However, if an investor reckons we've hit or already seen a bottom in this big tech correction, there is one ASX ETF that might be a top buy.
One ASX ETF to buy if big tech has bottomed
That ASX ETF is the Global X FANG+ ETF (ASX: FANG). This exchange-traded fund (ETF) is essentially a pure-play bet on the biggest US tech stocks. Unlike most ASX ETFs, it holds a very small portfolio, with only ten underlying holdings at present. Those ten underlying holdings consist of six of the magnificent seven stocks (Tesla misses out), in addition to Netflix, Crowdstrike Holdings, ServiceNow and Broadcom.
These ten shares are given an equal weighting of approximately 10% each.
As such, if an ASX investor is looking for a quick and easy way to invest in the biggest tech stocks on the US markets, this ETF is a prime candidate. On an on-going basis, it is more expensive owning this ETF than the individual stocks, with FANG charging a management fee of 0.35% per annum.
As one would expect, FANG has also had a volatile few weeks. Between 18 February and 11 March, FANG units cratered by 17.22%. Those same units are still 17.5% down from where they were on 18 February.
Let's see how the rest of 2025 treats the Global X FANG+ ETF. If we have indeed seen a bottom for big tech over in the US, this will be an interesting fund to watch.
