Sun Life Financial is trading 10.31% lower at CA$102.71 as investors react to third-quarter results and analyst downgrades. - Underlying EPS rose 10% to $2.05, but analysts cited elevated U.S. long-term disability losses and substantial MFS outflows. - National Bank and TD Cowen lowered their ratings and price targets. - A sharp broader-market sell-off added pressure, though company-specific earnings concerns and downgrades appear to be the more direct catalyst.
