There is already two companies starting exploration drilling offshore in the falklands but you can expect a long wait before anything meaningful happens. Due to the fact that its uncharted territory down there in as much it such extreme conditions etc. Add the fact the argentinians want to restrict shipping in the waters between them and the islands. There will be a lot of political manouvering to come.
REgards the stock markets, I have a stocks and shares ISA that I invest in every month that is to be my retirement fund. But as I'm only 35 and have hopefully only about 20yr left to work (thats the plan anyway) a falling market is good for long term investors. Cheaper stocks mean more for your money and so I'll have more shares when the market starts to recover. Other than that I try to ignore it because its still not nice seeing your investments falling!
