By Lloyd Khaner Just when it seemed like we might ease into the summer doldrums without incident, June served up a subprime mortgage debacle that stress-tested the financial markets and the players in them.

Potential concerns on the horizon include the hurricane season, private-equity-buyout burnout, unnerving Chinese market volatility and a tightening in global liquidity that could threaten the now-more-tentative hedge fund environment. Is a full-blown correction in the offing? No one knows, but working on your shopping list might be a good use of that hour you once spent watching The Sopranos.
