You apparently o not understand short selling, so I will attempt to explain it to you one more time despite your obvious lack of intelligence and your desire to just be negative.
The recent pattern of daily trading has been for the price to rise in pre-market trading, an indication of demand, followed by a rise in price at the opening, followed by a series of small sales at the bid which is an attempt to drive the price back down or limit the rise. This is a graphic indication of short selling.
However, most recently the shorts have not been able to cause a decline in the price and so we are now trading at $18.25, the high for the day. The inability of the shorts to achieve their goals is due to several factors--1) some of the short sellers have covered and moved on in the face of strengthening demand, 2) with more than 35% of the float sild short, it is increasingly difficult for short sellers to borrow shares to sell short. I was recently contacted by 2 brokerage firms where I hold substantial shares of LFMD to see if I would like to earn interest income on my holdings by lending shares. (of course I declined).
We may see a short squeeze develop soon as remaining shorts scurry to buy shares to cover their naked position.
An analogy may help you understand. Short sellers sell assets they do not possess and must later cover the sale. So, by analogy, if you sold brain matter you would be a short seller.
