- Four Big Tech companies - Apple, Microsoft, Tesla, and Meta - lost a combined $625 billion in market value this month.
- That may be largely due to seasonal trends as August tends to be a weak month for equities, historically.
- The tech selloff comes against the backdrop of a broader decline in US equities, triggered in part by higher bond yields.
It's been a tough month for Big Tech stocks.
Some of the world's biggest companies lost hundreds of billions of dollars in market value in August as the US stocks head for its worst month of 2023.
