Traders buy "disaster" put options to hedge against the risk of a crash in US technology stocks.

Options traders are becoming increasingly worried that tech stocks will plunge in the coming weeks, and are rushing to purchase "insurance" as a result. Since the market crash triggered by Donald Trump's comprehensive tariffs in early April, the Nasdaq 100 index, which is dominated by tech stocks, has risen by nearly 40%. This rally has been driven mainly by large tech companies, with the Bloomberg Big Seven Index surging by almost 50% from the bottom on April 8; the index's components include Nvidia, Meta Platforms, and Microsoft. However, there are concerns in the market that this rally is masking some weaknesses. From the upcoming Federal Reserve Jackson Hole Symposium in a few days, to Nvidia's earnings report due next week, there are potential triggers for a stock market downturn.
