Can anyone explain this? |

for each stock, three choices: remain, sold, given, so 3^6 in total |

For each stock you have 3 choices (or Outcomes) thus the number of possible outcomes is:3*3*3*3*3*3 or 3^6 |

i got it right, but what is the logic against using 6^3 instead of 3^6? |

Each stock can be distributed 3 ways, so 3^6 (3 ways each stock) |
