For more than a year I worked on this concept:
Would it be possible to consistently beat the $SPY by investing into the single strongest sector(s) and rotate regularly. I wanted some simple and a method that was easy to determine strength. For a while I tracked (and invested into):
XHB
XLK
XLU
XLI
XLF
XLE
XLV
XLP
XLY
QQQ
IWM
Based upon which ETFs sectors were the strongest performing and inside an early Bull Trend. The concept proved to be quite difficult to manage.
Summer of 2013 - I decided to simplify and examine only 6 sectors that were essentially based off the diversification concept from the American Association of Individual Investors. The 6 sectors comprised of:
IVV - Large Cap
IJH - Mid Cap
IJR- Small Cap
EFA- International
ADRE - Emerging Mkts
IEF - Bonds
Rather than diversifying into each of these funds, I backtested a strategy to see what would happen if I invested 100% into the strongest sector and rotated monthly. I call this the SH Monthly Rotation Strategy and I bench marked that to the $SPY that was a buy and hold..
The results of a 10 year back test are pretty strong.
Beginning with a portfolio of $10k in 2003 - today:
The SH Portfolio balance would currently sit at $135k vs the $SPY at $26k.
While the past couple of yeasr the $SPY has outperformed this strategy by a couple of % pts each year. The SH Portfolio Rotation Strategy in 10+ years has never suffered a losing year.
I've participated in the strategy since Nov 2013, and update the latest rotation on my site.
