Silicon Motion Technology CORP trades publicly (SIMO), so every calculator below prices off the live SIMO price — no 409A estimate required. If you hold Silicon Motion Technology CORP equity (incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs)), your after-tax outcome turns on a few linked decisions.
The tools below model each of these: whether exercising ISOs triggers the alternative minimum tax (AMT) this year, and the share count that keeps you under the crossover, whether to sell RSUs at vest or hold for long-term capital-gains treatment, and how much SIMO concentration to carry versus diversify or hedge.
