"However, we think this self-help potential as well as the current positive market outlook is now reflected in estimates and valuation," read this morning's research note. "We also continue to note MGGT's lower exposure to the large jet market (~35% of revenues) vs. peers provides less potential for top-line-driven earnings growth." Analysts concluded: "We downgrade our rating to 'equal weight' (from 'overweight') with a 550p PT (up from 530p) & prefer Senior PLC ( LON:SNR ), where we see more top-line potential, and valuation and earnings aren't based on self-help." Meggitt shares were down 0.6% to 539.6p in mid-morning trading.
