Tech just can't get out of its own way. Or, more aptly, bonds just won't get out of tech's way. This week was a fitful, spasmodic exercise in the type of "churn" discussed here at length on Wednesday. It culminated Friday in another awkward session that found yields rising sharply, pressuring tech anew. It's virtually impossible to make the case that overvalued pandemic stocks, high-flying tech shares, and other perennial, secular growth winners have de-rated enough to make them "bargains."
