Tim Hughes, head of sales trading at IG Index, said: "After closing at a six-year low yesterday, investors clearly got up early to go bargain hunting this morning.
"As a result, the FTSE was already up around sixty points by midday. But we saw a similar initial rally yesterday too, so investors were asking themselves what was driving the rally and would it last?"
He added: "Its still nervy times ahead. Today saw the inevitable rebound after the vast losses of the past days, but were certainly not out of the woods yet.
"The general feeling is that its still too early to call this as a definitive turning point and investors are unlikely to be hitting the buy button with abandon at this stage. The fabled dead cat bounce has almost certainly played a part today, with uncertainty still hanging firmly over the future direction of markets."
