How would an investor have "inside info" - Shells do one thing - Merge.
Sometimes investors can find out what is coming by calling the company.
You can bet though that MM's have strategies on a few OTCBB / pinks.
Most they could care less about and just trade with the flow selling at top and then walking down and covering. They make their money on the spread and covering post run up.
Some though, with very small floats, and non-dilution histories they know will run.
Management here seems pretty tight.
My guess would be that someone had a sell in at $10 and moved it to $15 to cancelled it al together.
