Bear Markets Through the Decades

Several months ago, Steven (my trading buddy) and I were talking about bear markets. I felt that bear markets seem shorter and shallower now compared to the past. I thought this would be a quick and easy research project and blog post. Nope. As I generated numbers, more questions and research paths would be generated.

My questions are

  • Are bear markets shorter?
  • Are bear markets shallower?

Sell in August and Go Away

I was going through some old issues of Technical Analysis of Stocks & Commodities looking for some ideas to test. In the November 2019 issue, I came across “Stock Market Seasonality: A Global Phenomenon” by Jay Kaeppel. The basic idea was that global markets share the same “buy in November and sell in May” phenomenon as the US market.

This got me thinking about how markets have changed since 2012 or so. My theory is that before 2012, this pattern was better than either buy and hold or other start and end months. But after this time, buy and hold or longer hold dates would be better. The reason is that the Fed is involved in the market more and keeping bear markets much shorter.

UPRO/TQQQ Leveraged ETF Strategy

Recently a reader sent me a leveraged ETF strategy that he wanted tested for the blog. Over the last couple of months, I have been noticing renewed interest in leveraged ETF trading. More clients are coming to me to test out leverage trading ideas. I have been testing my own ideas. What I liked about this strategy is that it moved between leveraged ETFs, non-leveraged ETFs and TLT.

Reducing Whipsaws When Using 200-day Moving Average for Market Timing

I was working on testing a market timing indicator that I read about it. It was showing some promise and the next step was to compare it to my benchmark. My benchmark is using the 200-day moving average. But an additional rule removes a lot of the whipsaws that can happen.

After doing the comparison, the market timing indicator compared well. But then I realized I had not written a blog post about my additions. I touched on it in the Market Timing with a Canary, Gold, Copper, LQD, IEF and much more post.

For me, the goal of using the 200-day MA to trade the SPY is to get about the same CAR but with a significant reduction in MDD.

Using Historical Volatility for Parameter Adjustment

The AllocateSmartly website often has interesting posts. Recently I was reading the article Trending Fast and Slow and thought about other ideas to test. The article is based on research on trading the SPX and depending on the current historical volatility one would either use a 12-month or a 1-month lookback to decide whether to enter or exit the trade. I had tried similar ideas before but not this one.

SP-500 Seasonality

I’ve been seeing lots of seasonality type charts on the S&P500 where they take the average return for each day of the year and then create a return curve for the year. The chart often ‘shows’ the sell in May and buy in November flatness of the returns. And then the holiday end of the year run up.

Steven, my trading buddy, sent me yet another chart and I noticed something I had not seen before. A beginning of the year downtrend from January to mid-March. This got me thinking. How much does the start of the data set impact these charts?

Rolling Returns for the SP-500

I just got back from a long vacation in Iceland (highly recommend visiting). As usual, when people discover what I do, they ask me about the markets. Several people were worried that the markets are too high. Then I read that the 20-year return of the SPX from 2001 to 2020 was way below the average 20-year return. My thinking was how could the massive run since 2009 not have gotten us above the average. As usual, I had to test it.

How to turn off a strategy using historical volatility

A very common question I get, is “when should I turn off a strategy?” Given the very volatile markets we have had the last few months, I can relate. Some strategies can thrive in these high volatility markets. While others can suffer.

In the June 2020 issue of Technical Analysis of Stocks and Commodities, Perry Kaufman writes an article about using the historical volatility of the equity curve to decide when to turn off a strategy. I always read Perry’s articles because they are full of good ideas and this was another one that I liked and had not tried before.
