What the numbers mean
Over this 19-year window the Swensen Lazy Portfolio compounded at roughly 6.03%per year. That growth was not a straight line: the strategy's worst peak-to-trough decline reached -27.6%, a reminder that even the steadiest allocations go through painful stretches.
Its best single year returned +21.7% (2009), while its worst year fell -21.3% (2008). Adjusted for inflation, the ending $30,563 is worth about $18,044 in 2007 dollars — the real purchasing power your money would have gained after rising prices are stripped out.
