Right. A "full lot" is 100 shares and any number of shares traded below 100 is considered an "odd lot".
Now here's something not everyone knows: When you look at chart data with open, high, low, and close prices, did you know that odd lots do not contribute to that chart data? Example: if the highest full-lot trade for a day was $139.14 but the highest odd-lot trade was $139.20, you will see $139.14 as the high on the chart. I think this was due to a past convention of not posting odd-lot trades to the TOS, Time of Sales. Although you can see odd-lot trades on the TOS nowadays, data providers seem to be sticking to that past convention. Robert -
