I sold my shares of LJPC awhile ago but fwiw there are far worse "garbage" biotechs than this. The whole sector is reaching bubble-like proportions and supply is hitting the market at a fever pitch via financings. I'm not saying that bios won't keep rising further but eventually all bubbles pop and when they do things can get ugly in a hurry.
Very rarely do I sell exact tops and buy exact bottoms. Like most traders more often than not a stock will rise further after I sell it and drop further after I buy it. Bought around where it is now, sold in the $3.80's and rebought at $2.91. Regardless of how the stock has acted the past few days this news really is a big deal for this company. GL.
