I went 3-for-4 with my August 2012 stock market predictions, correctly calling advances in VTSMX (US equities, dominated by large caps), VDMIX (foreign developed equities), and VEIEX (foreign emerging equities), but missing on my prediction of decline in NAESX (US small caps). I am now 15-for-24 in my predictions all time (i.e. since March of this year), just far enough above the 50/50 odds to start entertaining delusions of grandeur.
If my 62.5% accuracy doesn't impress you, then you are either (a) unaware that it's way better than vast majority of market gurus or (b) intelligent enough to realize that until I accumulate, say, a decade worth of monthly predictions there's no rational way of judging my predictive powers.
For September 2012 I predict declines in VTSMX, NAESX, VDMIX, and advance in VEIEX.
