Stock price when the opinion was issued
When you buy these, you're saying you want less emphasis on the Mag 7 and more on the other companies. You're saying mid-cap stocks are going to do better. At this point, he'd say the mid-cap sector is preferred. He's bullish on small caps in the shorter term, and mid-caps also benefit in that environment.
(Note the short timeframe.) At the time, market was still in the post-election honeymoon, and the bull market was finally getting to the smaller names. Had a run, and then petered out. Enthusiasm changed on small- and mid-caps, and retrenched to large-cap defensives.
