Technology and Healthcare sectors lead with recent "Strong Buy" ratings. Notable large-cap additions include MELI, TTWO, and VRT on Monday, with CHTR also upgraded. ANET and COIN received "Strong Buy" initiations on Tuesday. Conversely, several large-cap stocks faced "Hold" downgrades, including CSCO, HAL, and HCA on Monday. PARA saw a "Strong Sell" downgrade on Monday, and TSLA was downgraded to "Hold" on Friday. Average target price upsides suggest continued momentum for many upgraded names, but caution is warranted in some previously favored growth sectors.
