Apple, my biggest tech holding

Nearly 43% of Warren Buffett's Portfolio Is Invested in These 5 Tech Stocks: Apple, TSM, Activision Blizzard, HP, and Verisign.

So for me I invested apple at the biggest account, up to nearly a half of my portfolio. Last year, I increased my holding in TSM and gained some profits. But because of some geopolitical factors, TSM will lose its strength so I reduced it around one month ago.
