StumpGrinder suffered losses in May and June. We moved to cash in late June. Here’s a blog explaining why we believe StumpGrinder (and other strategies) were down during that period. We’re planning a reentry to the market, but with a change up in assets. Here’s a post covering some of the equities we’re considering for the new portfolio.

May 2, 2013: 1st day after rebalance

Just looking at performance after market open. Our new portfolio is up 15 bps more than the old one would have been. Nice to see validation that optimizing and rebalancing helps, even if it is just a small glimpse.

May 1, 2013: April 2013 performance

StumpGrinder performance for April 2013 compared to our benchmark and the S&P 500.

StumpGrinder performance for April 2013 compared to our benchmark and the S&P 500.

Highlights: We’ve completed our first month with the new ETFs. Prior to April we were using a similar mix, but only 4 ETFs. We’re now using 12.

Mid-month we ramped up our leverage to 2x, so we’ll be seeing slightly higher volatility and return (we hope). Our volatility is still less than 1/2 the market’s so we could potentially consider even a bit more leverage.

Monthly performance: Performance for the month was good. In terms of cumulative return at 2.46% we outperformed our benchmark and the S&P 500. We also outperformed both in terms of low volatility and high Sharpe Ratio.

New benchmark: We’ve switched from the S&P 500 to a more appropriate benchmark on the advice of one of our advisors. We will certainly refer to the S&P 500 from time to time, but our key benchmark will be the S&P Target Risk Moderate Index, SPTGMU. It’s a more appropriate benchmark because it represents a similar balance of fixed income, equity and international exposure. According to S&P: “It provides significant exposure to fixed income, while also providing increased opportunity for capital growth through equities.” For comparison purposes we use the ETF AOM to represent the index because the ETF value history includes total return information (price + dividends) that is not available with the index by itself (price only).

According to S&P: “The S&P Target Risk Index Series is composed of four multi-asset class indices, each corresponding to a particular risk level. Like the related S&P Target Date Index Series, the asset class mix is determined once a year through a process designed to reflect the overall investment opportunity of the represented markets. Each index is fully investable, and is designed to provide varying levels of exposure to equities and fixed income.”

YTD performance: Our year to date performance continues to excel with a remarkable Sharpe Ratio of 6.09. We will be surprised if that ratio remains that elevated, but we will certainly take it! We’ve outperformed our benchmark YTD in terms of cumulative return (4.75% versus 3.84%), volatility and Sharpe Ratio.

The S&P 500 outperformed us in terms of cumulative return. But now that we’re levered up to 2x, we’re hoping to give the S&P 500 a stronger run for it’s money in terms of total return, while continuing to outperform in terms of Sharpe and volatility.

Friday April 19, 2013: The Stump Weathers Market Volatility

The month of April has provided a great opportunity to illustrate StumpGrinder’s performance in a volatile market.  The market (S&P 500) has been up as much as 2% and down as much as 1%. StumpGrinder has followed the market a bit, but overall has survived the volatility well.

We close out this week up about 1.1% for the month, and 3.38% for the year. The market is down 0.37% for the month, but up 9.18% for the year. The market is doing very well YTD.

We’re OK with the lower return YTD because we’re getting it with much much less volatility. However, we’re levering up now to 2x, so we expect to see higher returns now going forward.

Friday April 12, 2013: Market Down, Stump Up

We’ve had an amazing week for the market: 4 days of record highs, with a slight drop today.  StumpGrinder has had a good week also. Here’s a chart showing StumpGrinder versus the S&P 500 over the last 2 weeks.

These last two weeks provide an opportunity for a discussion of risk versus reward. Consider the question: Over the last two weeks, which performance is better: StumpGrinder or S&P 500?

I suspect many of you will answer that the S&P 500 has done better because it has provided the highest return (1.35% vs 0.90%).

But how might you have felt on April 5th when the S&P was down nearly 1% and StumpGrinder was up 0.5%. The point is that over the last two weeks the S&P is up overall, but compared to StumpGrinder it is volatile and perhaps more risky. Also, many pundits expect a market correction downward.

Here’s another consideration: Based on this chart, would you feel better putting your mom’s retirement account into a portfolio that performs like StumpGrinder or a portfolio like the S&P 500?

Investment professionals consider this tradeoff in terms of a reward/risk ratio, where “risk” is defined as volatility. It is called a Sharpe Ratio (named for William Sharpe, a Nobel Prize winning economist). In terms of Sharpe Ratio, StumpGrinder is doing much better than the S&P 500 over these two weeks.

We’re going to begin, soon, to leverage StumpGrinder, so I hope we’ll see our strategy provide strong returns, and low volatility.

Thursday April 11, 2013: First checkpoint

Actually traded performance of StumpGrinder

Four days ago on Monday April 8, 2013, we launched StumpGrinder . We’ve had four up days since that time. The market has also been on an incredible tear, hitting record highs each day.

So, why not just buy the market?

If you were to buy the market, I’m assuming you’d buy the SP 500 ETF: SPY. We’re using that as our benchmark, and it is up over 9% YTD. That’s great performance, but it is also volatile. The short answer is that, right now, the market is the hare, and we’re the tortoise. We’ll catch up when the market “correction” (drop) occurs, and lots of folks think that’s coming soon.

The longer answer is that StumpGrinder includes a wide variety of asset classes.  Overall, we expect all of these assets to increase in value. On any particular day some of them go up, some go down, but they balance each other out, so we see smooth upward returns. On significant market down days the non-US stock holdings will prevent a large loss.

Our performance metrics, year to date, including baby StumpGrinder:

  • Cumulative return: 3.14%
  • Sharpe Ratio: 6.17

Yeah, Sharpe Ratio is really 6.17, but Sharpe Ratios over short periods of time are often exaggerated. We’re not expecting that for the entire year of course.

Oldest: January 1, 2013: Before Launch: Baby StumpGrinder

We’re including the performance of our previous strategy from January 2, 2013 until now in our performance reports. That strategy was very similar to the one we’re trading now, but it included only four securities: SPY, GLD, BOND, BAB. We’re expecting even better things for the new StumpGrinder.
