buy and sell, page-7

What you are looking for is some education on fundamental analysis. There is a heap of stuff available through websites like Investopedia. This woulg give you more confidence in making your decisions. Also it doesn't hurt to make sure you only buy shares in companies that are fundamentally sound so that even if the price goes down below where you are comfortable selling you can take a break and wait till it goes back up again.
One thing is for certain it doesn't help to keep looking at the price and wringing your hands over your losses. That's a sure fire way of getting so wound up you sell just as the shareprice is bottoming out.
And you don't always have to buy more when they go lower just to dilute your price, especially while you are gaining confidence at reading charts. Unless you really want to increase your holding in a particular company.
BTW if you look at a long term BUD chart there is support at 26 cents so it is probably due to bottom out around now. That's what I'm doing. The market failed to acknowledge the importance of a recent announcement that BUD made but certainly once they start to announce earnings projections we will see some positive response. in the meantime, stop worrying
