This is true (although I’m buy side and am not an analyst). Banks will sell their reports to customers/tip hand on upgrades before doing it, especially the big ones, since these upgrades can really move stocks.
More over, large buy side funds won’t release reports since they make more money trading on their research than selling it.
However this concept of cheap shares doesn’t really exist in stocks as large and liquid as amarin (now, it did when we were a 600m company). There is too much risk to sell now to buy back cheaper...getting caught on the wrong side of that trade is not explainable. We have too much visibility and popularity at this point, and with a BO looming, no one bullish the stock would dare sell millions of shares. Those are more likely bear raids or actual skeptics. Based on the fund raising, unfortunately the banks proved they could buy cheap shares ($18) for size when they feel like it
