My wife, Sari, and I love old movies and one of our favorites is the Long, Long Trailer, staring Lucille Ball and Desi Arnaz.  Desi and Lucy are newly-weds who decide, instead of buying a house, to purchase a trailer home which they hitch onto the back of their car and set off on their adventures.  Soon, without any idea of how to drive such a contraption, they find themselves ascending into the Sierra Nevada mountains, driving up steep, narrow and twisty mountain roads.  Unbeknownst to Desi, Lucy decided to collect rocks as souvenirs along the way which she hid all over the trailer, adding extra weight to an already dangerously unwieldy vehicle.  The funniest part is watching them making small talk, pretending nothing is going on, as their car engine roars, gears squeal and little rocks spit out from their tires, over the cliffs and out into the abyss below.  The contrast between the nonchalance of their conversation and the terror in their eyes is priceless and it only increases as they head over the peak and begin to descend.

The most dangerous time, both for oversized trailers and central bankers, is when you begin to descend from a peak.  Recent data suggest the Fed should, finally, begin to cut rates in September.  This operation could work out OK.  However, it is a delicate one and, particularly, when both markets and portfolios appear to be overconcentrated, it is important that investors take what steps they can to maintain or regain balance in their portfolios.
