Wall Street’s speculative trades rebound after sharp losses

The semiconductor sector lost more than $1 trillion in market value on Friday. By Monday, traders were already buying the dip.

The selloff and the snapback

On June 6, US chip stocks cratered in a session that wiped out roughly $1 trillion from the semiconductor group, which had been valued at approximately $1.4 trillion before the rout. That translates to about a 14% haircut in a single day. The ten largest decliners alone accounted for $1.1 trillion in losses, meaning the damage was heavily concentrated among the biggest names in the space.

By June 8, traders flooded back into the same names they’d been dumping, sending chip stocks and AI-linked equities sharply higher.

Micron Technology offered the clearest illustration of the volatility. The memory chipmaker plunged 13.3% during the Friday selloff, only to surge 9.9% on Monday. Micron’s shares had already more than tripled on a year-to-date basis heading into the turbulence.

The PHLX Semiconductor Index, along with Nvidia and other major semiconductor companies, helped anchor the broader recovery.

What this means for the AI trade

Concentration risk in the semiconductor sector is extreme. When the top ten decliners account for $1.1 trillion in losses out of a $1.4 trillion sector, a small number of mega-cap names are driving virtually all of the action.

A sector that can lose 14% and recover most of it within two trading days is one where position sizing and risk management matter enormously. Micron’s ability to triple year-to-date and still swing 23 percentage points in two sessions illustrates the scale of volatility in the current market.
