AMRI is thinly traded and therefore more easily manipulated than stocks with larger volumes.
I bring this up because of the posts below, where it seems someone is trying to drive the price down, either to buy it at a lower price or because he/she is a short-seller who wants to profit from the decline.
If we AMRI shareholders don't want to see the stock price swing around wildly, my advice for all of us is not to keep our shares in a margin account, where they can be borrowed by short-sellers.
Instead, hold them in a non-margin account because they can't be lent out by your broker from such an account.
Short-selling has the effect of depressing the share price. Here's how it works: they borrow a stock, sell it with the aim of hopefully buying it back at a lower price, and then return it to the rightful owner. But as I say, only stocks held in margin accounts can be borrowed in the first place. So if you hold AMRI in a non-margin account, less shares will be available to be shorted.
By the way, this is all transparent to you, the owner -- the shares you own still appear on your statements, and if you wanted to do sell them yourself while they were loaned out to a short-seller, the broker would go through backroom maneuvers to accomplish the sale for you and you'd never even know about it.
So, why make it easy for short-sellers to borrow and short such a thinly traded stock as AMRI? Consider keeping it out of your margin accounts.
