Drinks giant SABMiller has served up an excellent set of results today, putting some new fizz into the share price as it beats expectations. With the post-2009 trend solidly intact, investors are looking to toast further trading updates.

Online supermarket Ocado is enjoying a surge after news about a cash raising. However, questions linger about the future of the company as it seeks to expand outside its Home Counties heartland.

Investors in Supergroup have enjoyed a rollercoaster ride, having seen the shares hit all-time lows this year before rallying strongly. Today's results show further progress, so perhaps it's time for a more sober look at the company now that the excitement has dissipated.

Today's results from M&S mark a mid-point in the CEO's three-year turnaround plan. It seems to be on track, with sales holding up in the UK. International expansion appears to be gaining priority, which should help M&S reduce its reliance on the UK market.

BP has spent the past two years in recovering from the 2010 Deepwater crisis. Its recent results show progress is being made, while changes in its Russian operations mean that the future looks brighter than it has for some time.

Better than expected jobs data has kept markets supported, but it does feel as if some of the momentum from recent months has started to flag. The focus has now switched to the US earnings season, and so far the results have been encouraging.

As widely expected, this week saw the US central bank do more to stimulate the economy — and it ended up being quite a lot more than markets were expecting. The net result is that US stock markets are back to pre-financial-crisis levels; the euro recovery continues and even gold has woken up in recent weeks - but will it last?

Disappointment at the ECB press conference brought volatility back with a bang this week – although a better-than-expected US unemployment report helped markets claw back the losses. With these major events out of the way the next week could be calmer, but thin trading during the summer months can always present its own problems.

It's a relatively calm period at the moment despite the Libor scandal occupying the headlines. It's starting to look like the usual summer slowdown, although of course last July ended up being the calm before the eurozone crisis storm. Is this year different?

The focus for markets this week should not come as a surprise to anyone – Europe once again. With the latest in a long line of EU summits set to start on Thursday 28 June, it could well be a cautious few days as investors wait to see if there are any fresh ideas on how to contain the crisis.
