It is super speculative until the next 4c (thanks to the company for providing the report) but based on my knowledge of the T20 and paying a private investigator on the register it would be my guess that it could be:
Oklahoma Energy Consultants, Inc. (OEC):
Were issued 30.5m shares at 0.0075 in exchange for payment. Plus the $340k issued in December 2020. As per the last 4C they held under $20m. As their facility is coming up it makes sense for them to sell at a very nice profit as the company has the cash to pay them out or will likely refinance them at a more competitive rate given its financial position.
Merchant:
In their April update, they were 50% up on their position:
https://www.merchantfunds.com.au/wp-content/uploads/2021/05/MFM-Newsletter-April-2021.pdf . Based on today's SP they have around $4.9m plus a serious amount of free options (they had 28m as at the annual report). The position is getting large given their fund size so I completely understand why they would be selling down their shares and holding the options. They also hold down their position in Dec.
Most of the other names are long-term holders and appear to be accumulating.
I know I keep on going on about liquidity and it is hard/pointless to chart microcaps and this is another example of why. Let's use OEC and just the February share issue as an example (note the prior ones they make much more $$$), they were provided 30.5m shares at 0.0075 per share (US$117,181 or call it $150k ish in AUD). That $150k is now worth $671k at today's close and over $1m at the high. That is more than the 12% per year that they are getting in interest for the US$4m loan they provided. I cant be bothered doing the maths but I bet they have made the loan back in profit easy.
Where i am getting to is that people are going to buy and sell all day every day, the company is going from a $10m MC to grow well over the $100m mark. It will outgrow the original holders/funders as it has an established track record and is much more financially stable ect. You cant blame people for selling and moving on or taking their profits as everyone has a different appetite for risk.
The biggest issue with BRK to date is not the drilling of oil or the early days where they struggled with cash flow it is the so called twitter/HC traders who pumped this stock to 3.8 based on hype. This has left a bad taste in people's mouths when there is a down day and the panic sets in. They have no understanding of the underlying business and just want to make crypto like profits based on momentum and finding someone else to invest. There is no doubt, this company has a very bright future and its SP will hit amazing levels. While the pumpers and pumping the company are drilling and doing what they do best, the smart money is investing and the time will come.
