"Re: your comment on Monday evening: "I would not trust the first bounce, which may occur mainly on short covering". Wise advice indeed, as trading on Tuesday and Wednesday shows us. Unfortunately I was tempted to make some purchases on Tuesday around mid-day, but nothing like as much as I would have done if I had not read your comment."
David Fuller's view I am glad the comment helped.
Tactically, your decision to buy on weakness is very sensible. However you may wish to do so incrementally, particularly as Wall Street only really broke downwards last week and the growth economies have yet to announce a shift in monetary policy.
