Why Tech Sector Correlation Matters Now
March 22, 2025
Something interesting happened in February that
a lot of retail investors missed. Technology
stocks that normally move somewhat independently
started clustering together in their daily
movements. When correlation increases like this,
it changes the actual diversification benefit
you're getting from holding multiple tech names.
I've watched this pattern before—usually during
periods of uncertainty when investors treat
entire sectors as single bets rather than
collections of distinct businesses. It doesn't
mean you should panic and sell everything, but
it does suggest your tech-heavy portfolio might
not be as diversified as you think.
Key Considerations
- Correlation coefficients between major
tech stocks reached highest levels since late
2023
- Sector rotation patterns suggest
institutional investors reducing concentrated
positions
- Historical precedent shows these periods
typically last 3-5 months before normalizing
- Consider reviewing position sizing if
tech represents more than 35% of your equity
allocation
The practical takeaway? Look at your holdings as
groups rather than individual stocks right now.
If you own five technology companies that all
move together, you effectively have one position
split five ways. That changes your risk profile
more than most people realize until a correction
happens.
