IHS
Best and worst times to own IHS in the past two years
Buying and selling at the close. Each colored stretch is the best or worst window for that holding period, green for a gain and red for a loss: longer holds are wider and darker underneath, shorter ones brighter on top. The grey line is the full two years. Letters mark events inside the windows (E earnings, A analyst, I insider, M mention spike, V volume spike, T theme move, N news). Hover a period above the chart to pick it out and see only its events; click it to hide or show it.
