What’s the power of compounding?

INVESTMENT NEEDS SKILL which is "buying" shares when market is on downfall and "selling" shares when market is in upswing.

     LIKE GOVT OF INDIA INVESTED 'WHEN PUBLIC LTD COMPANIES WERE ON DOWNTREND IN 1960's' AND IS DISINVESTING 'WHEN PUBLIC LTD COMPANIES ARE IN UPSURGE AT PRESENT'.
