This is only my opinion. It might be true the cross is for taxe loss purpose. Is the trade is by the same people ?
To buy back the stock you need to wait 30 days to claim the loss, which in this case is very close.
However there is one thing the persone who buy back the stock still have confidence that the stock will rise
again. Unless we have a clear signal that LFD indeed has something coming, we shareholders just don't have clue what is going on with LFD.
