The Nasdaq-100 home to Apple Microsoft and other Big Tech stocks just entered a bull market—and now looks like as good a time as any to take profits.

That might seem like a weird thing to do. The Nasdaq-100, which contains the 100 biggest stocks in the Nasdaq, has gained 21.9% since its Dec. 28 low, meeting the technical definition of a bull market, which starts with a 20% rise off a bear-market low. Why dump what is working?
