It's likely to be institutional. Even with self-wealth, a $300 trade that gives you 20% gain - i.e. $60, only Endy up being $40 profit due to buy/sell fees. Then tax on the income brings that to $20-30.

The trend is clear though. Typically in the last hour to 30 mins of trade, there are one or more low volume, low-ball trades. Particularly on a Friday. Clearly taking advantage of how the share price is recorded and announced (i.e. end of day or week price).

I don't know what the motivation is, but potentially trying to keep the price down so they can accumulate for a future announcement on sales. Or maybe they invest in a stock that might be considered a competitor. If others can offer an explanation... I'm all ears.
