Executive Summary The time period under consideration had two bear market crashes, when the market had a 50% loss. The IULtype strategy avoided those crashes, but at the cost of delivering substantially less overall gain. One test was run where the last 10 years had a $1500 monthly withdrawal. By coincidence, the start date for the withdrawals was at the bottom of the first crash. Even so, the IULtype strategy had a lower return.
An alternative strategy was also tested, which uses a simple timing signal to move in and out of the S&P500. This strategy has less volatility than the S&P, but higher volatility than the IUL strategy. It delivered a better overall return than the IUL strategy.
The IULtype strategy is claimed to deliver marketlike performance without market risk. It does not. It does eliminate market risk, but it has nowhere near market performance  except perhaps in the shortterm.
After a suitable time to allow for comments & discussion, I will upload the spreadsheet for public access.  Here are the assumptions: S&P500 index from 1/1/1975 to 1/1/2013. This is a period of 38 years, or 456 months. Assumed dividend yield: constant 2.25%
Secondarily, the 2nd half of this period is also computed. 7/1/1993 to 1/1/2013
Initial deposit (purchase) of $10,000 Subsequent deposit (purchase) of $100 each month. ($1,000 per month is much too high.) That's a total of $55,600 over the 38 years.
The IULlike rules are: Index only, without dividends. Floor of 0% annual return. Cap of 12% annual return. Annual fee: 0.00% (This is the most optimistic fee. A fee of 0.50% was distinctly worse.)
For the markettimed strategy, cash earned 1.0% interest when out of the market.
For the Sortino Ratio, the MAR is 3%.
No taxes are considered. No trading fees are considered.
 Three strategies were compared. 1) Buyandhold of the S&P500 index, including dividends.
2) Market timing overlay on the S&P500 index, including dividends. Each month, compute the 10month simple moving average (SMA) Buy when the S&P index is >= the SMA. Sell when the S&P index is <3% below the SMA. This turns out to be about 0.4 trades a year, with an average hold time of 715 days.
3) IULtype modified annual returns. If the S&P500 index return is < 0%, deliver 0% return. (0% floor) If the S&P500 index return is > 12%, deliver 12% return. (12% cap)
Explantion of the below statistics. CAGR = compound annual growth rate. Higher is better. StDev = volatility of the returns. Lower is better. MaxDD = maximum drawdown. The worst dollar loss from the 12month high. Lower is better. Sortino Ratio = a figure of merit, measures shortfalls of returns below the target MAR. Higher is better. Initial to: The final value that the initial deposit (only) has grown to. Final value: Final value including initial and monthly deposits and withdrawals (if any). Higher is better.
Note this: S&P500 B&H with and without dividends:
S&P B&H w/div CAGR 10.7% Initial to: $478,263 Final Val $932,426
S&P B&H EXCLUDING dividends CAGR 8.3% Initial to: $206,683 Final Val $444,769
Excluding the dividends cuts the final value in half. That's a large headwind for an indexonly strategy.
The statistics of the three strategies.
S&P B&H w/div CAGR 10.7% StDev 15.3% MaxDD 46% Sortino 0.66 Initial to: $478,263 Final Val $932,426
10mSMA CAGR 9.8% StDev 12.1% MaxDD 25% Sortino 0.72 Initial to: $348,844 Final Val $773,118
IUL floor/cap CAGR 6.9% StDev 1.7% MaxDD 0% Sortino 11.49 Initial to: $123,904 Final Val $337,235
A sortino ratio of 11 is excellent. That's the result of having a 0% "noloss" floor. The tradeoff is that the total return is substantially lower  only 1/2 or 1/3rd of the other strategies. Equity curve: See chart 1 http://i1131.photobucket.com/albums/m543/rayvt/chart1_zps8f...
Chart 5 is the same, except the scale is adjusted so that the period from Jan1975 to Jan1997 is more visible. The Oct87 Black Monday crash is quite apparent. That was a 30% loss in just 3 months time. http://i1131.photobucket.com/albums/m543/rayvt/chart5_zps8e...
Second half  Jul1993 to Jan2013
S&P B&H w/div Final Val $94,202
10mSMA Final Val $108,312
IUL floor/cap Final Val $85,487

For comparison, the full period with no monthly deposits:
S&P B&H w/div Initial to: $478,263 Final Val $482,219
10mSMA Initial to: $348,844 Final Val $351,493
IUL floor/cap Initial to: $123,904 Final Val $124,570
Equity curve: See chart 3 http://i1131.photobucket.com/albums/m543/rayvt/chart3_zps9e...
================================================= A 28 year accumulation, $10,000 initial + $100/mo from Jan1975 to Jan2003, then withdrawing $1,500/mo from Jan2003 to Jan2013. This is an 11% annual withdrawal rate based on the IUL value on Jan2003 ($162K), which is far higher the customary Safe Withdrawal Rate of 4%.
S&P B&H w/div Final Val $671,380
10mSMA Final Val $516,945
IUL floor/cap Final Val $65,453
