From the Volume and Mean Reversion post, a reader sent a suggestion to instead use the ratio of 10 day moving average of the Close times Volume divided by the 63-day moving average of the Close times Volume (CV10/63). I had not tried this before and wanted to see how well it would work. First Steps

Overall, I have had very little success integrating volume into any of my strategies. Either volume would have no predictive value or if it did, using it reduced the number of trades too much to be worthwhile. It has been a long while since I have looked into this and I had some new ideas. The Rules

A common question I get is whether mean reversion is still working. My response is I am still trading a mean reversion strategy but the edges seem to get smaller. Over the year I have investigated this. I was asked again recently and wanted to investigate again. Here are the results of my 2022

I am drawn to ETF rotation strategies. What likely draws me to them is that in general, these are simple strategies that do not trade that often. My goal with these strategies is to match buy and hold with less drawdown. What follows is a strategy I have known about for a while and tested but never

In my last blog post, Using Historical Volatility for Parameter Adjustment, I tested using historical volatility to determine trade rules. While reading the July 2022 Technical Analysis of Stocks & Commodities, I came across an article, “Is It Too Volatile To Trade?” by Perry Kaufman. I

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

Given the current rise in inflation, there has been a lot more interest in assets that do well during these times. Gold is one asset that is frequently brought up as an inflation hedge. I have also seen more lately about combining these two into a portfolio. Testing Notes The test range is from 1970

While talking to a trader, he mentioned an article in the December 2021 issue of Technical Analysis of Stocks & Commodities about Benford’s Law. I had read the same article and was wondering how it could be applied to my trading. Benford’s Law is often used to look for fraud. I am sure I am

I’ve been writing this blog for nine years now. Sometimes I am amazed about topics I have not covered and this is one of them. When developing a new strategy, these are the indicators I likely test: RSI, Historical Volatility and Internal Bar Strength (IBS). I had a reader send me an email

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

A member of The Crew recently asked me about the January Effect and if had I done any research on it. I had not. I have tested the December effect, which is buying the worst stocks of the year on December 1st, Should You Buy the Best or Worst YTD Stocks. From Investopedia, ‘The January Effect is a

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

A reader recently suggested leaving the limit orders for a mean reversion trade on for a couple of days. Typically, these orders are good only for one day unless the stock sets up again. I did not think that this would help but as I always tell my consulting clients when they ask me if an idea will

For the mean reversion strategies that I have created in the past and are trading now, they typically enter at the next day’s open or wait for a further pullback intraday before entering. My current mean reversion strategy, which enters on a limit down, was doing great until a few months ago when

Probably like a lot of you, I am an indicator junkie. Whenever I read about an indicator I have not tested and makes some sense, I got to try it out. Now, most of the time they turn out to not be useful for my strategies. While reading the April 2021 Technical Analysis of Stocks & Commodities, I

My last post on Different ranking methods for a monthly S&P500 Stock Rotation Strategy generated lots of emails on other ideas to try. Below are the results of these ideas Base Rules Backtest from 1/1/2007-12/31/2020. Buy It is the last trading day of the month Stock is a member of the

Recently for my own trading, I have been researching rotational strategies on both the weekly and monthly timeframes. The most common indicator that I use for ranking stocks is Rate of Change (ROC) of the closing price. I read about using Rate of Change on the EMA to rank stocks. I liked a small

In my previous post, Adding candlesticks to mean reversion setup, we looked at how various candle patterns could help individual trades. Now we will see how those results translate to a portfolio. And why I usually only do portfolio level testing. The Strategy Setup Rules Stock is a member or was a

My preferred chart style is a candlestick chart but I have never investigated candlestick formations to see if they can help provide an edge in my trading. I recently ran into this blog post, Do Candlesticks Work? A Quantitative Test Of 23 Candlestick Formations, where he did his own investigation.

Should you avoid trades that have recently gapped? What if you are trading a mean reversion strategy and a stock has recently had a large gap? Is that a good trade to take? Avoid? Does it depend on the direction of the gap? I did research on this about 15 years ago. Let’s see what the current

The most common question I get is how do you determine that a strategy is no longer working. It is also the question that I don’t have a good answer for. I have written several posts about this: Trading the Equity Curve, How to turn off a strategy using historical volatility, Broken Strategy or

Recently, I have been working on a strategy that trades stocks with low dollar turnover. The initial performance was attractive and I was liking the strategy. But there were two issues that I needed to deal with in the backtesting. How much slippage to add to these stocks. The strategy enters and

I had a long-time reader, Cristian Franchi, send me a mean-reversion strategy that he wanted me to test and write about. What caught my attention was the rules differing from what I typically see and use. Different ways of measuring strength of a sell-off and volatility expansion. Along with a

When developing a strategy, exits are often not given a second thought. If you are creating a mean reversion, you may default to using Close greater than the 2-period RSI. If you are trading a trend strategy, you may default to trailing exit using 14-day ATR. You try a bunch of entry filters but

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

Back in 2018, I wrote a post, Backtesting a Dividend Strategy, which was conceptually based on the S&P 500 Dividend Aristocrats. Just recently, Norgate Data started offering historical constituent data for the S&P 500 Dividend Aristocrats index. This would be a much ‘cleaner’ version

Has the market sell-off and subsequent bounce treated all stocks the same? A good portion of the bull market move from 2009 to 2019 has been led by the big-cap stocks. Did they hold up better during the March sell-off? What about with the bounce? Did the smaller-cap stocks have a bigger bounce? The

There is a saying: “in bear markets correlations go to one.” I wanted to see how true that is for both stocks and a basket of ETFs. Now they don’t go to exactly one, not that I expected that, but they take some large steps towards one. Definitions When calculating correlation, I am using the

Using strategy diversification is one of the easiest ways to improve the performance and reduce risk of your overall portfolio. Trading one strategy is risky because you never know when it may stop working or simply go into a period of under-performance. Given two strategies to trade, the questions

When this sell-off indicator triggers, it is correct 100% of the time! On average the market is up only 2.6% in 3 months. OR NOT! After big moves in the market, we often see “research” saying that “when the market has done X it will move Y%.” I had a reader send me such research asking for

In my last post, Inverse Volatility Position Sizing, I tested inverse volatility sizing on a monthly rotation strategy. I saw very little difference in the rest results versus equal position sizing. I was talking to a trading friend about the research and how I was surprised at how there was not any

Recently I’ve had several of my consulting clients come with a strategy that uses Inverse Volatility Position Sizing. The basic idea is that the more volatile positions have smaller size while the less volatile ones get a larger size. I have always been a fan of equal position sizing for several

In a previous post, Trend-following vs. Momentum in ETFs, I compared trend-following and momentum to see which produced better results on a basket of ETFs. In the post, I mentioned combining trend-following and momentum into one strategy to see if combined they can beat buy and hold more often.

In Tactical Asset Allocation (TAA) or Dual Momentum (DM) strategies, they often will use trend-following or momentum to decide whether to invest in asset or not. I have two questions. One, how often does either trend-following or momentum they beat buy and hold? Two, of the two which one beats the

Most of us focus our research time looking to find better entries. We don’t spend enough time thinking about our exits. I am definitely guilty of this. A popular way to enter a mean reversion trade is by using a limit order. I use that on the strategy on RSI2 Strategy: Double returns with a simple

We all have our favorite momentum indicators. One of mine is percent off 1 year high. This requires 252 data points and comparisons, plus a division. Another one is the 200-day moving average. This requires 200 closing prices, 199 additions and a division. A simple momentum indicator is Rate of

It is funny that my last post, Brazilian Jiu-Jitsu & Trading – Shiny New Toy, because this post is definitely chasing a shiny toy. I was reading the August 2019 Technical Analysis of Stocks & Commodities issue and came across the article “Swing Trading 10-Point Breakouts.” The basic

In my last two posts, Market Timing with a Canary, Gold, Copper, LQD, IEF and much more and Day of Month and Market Timing, I assumed that we earned no interest in cash. Most methods did a good job of telling us when to be in the SPY and when to be in cash. How much could we boost returns by

In my previous post, Market Timing with a Canary, Gold, Copper, LQD, IEF and much more, I tested several market timing methods. The signal was checked on the last day of the month. Now the question is what happens if we check on a different day? How different will the results be? The Test The

One commonality in my strategies is the inclusion of a market timing component. This could be a signal to go into cash or reduce position size or enter a ‘safe’ ETF. This applies to my swing trading strategies, my monthly rotation strategies and my Tactical Assert Allocation strategies. As a

In my last post, Avoiding Trades Before Earnings, I mentioned that I used Quantopian to do the research. Several readers asked about my thoughts about Quantopian and how it compares to AmiBroker. Some asked if I had left AmiBroker for Quantopian. What follows are my impressions after using

Over my last 16 years of research, one of the most asked questions is should you not take trades before an earnings release. I could never answer this question because I did not have the data. I can easily recall trades were a stock came out with poor earnings and crashed 25%. But without testing

I was talking to my trading buddy about the annoying part of trend following strategies. They may get you out of the major sell off but then you miss part of the run up. Using a 200-day moving average on the SPY would have got you out in late 2018. This would have been within 10% from the top and

A common question I get from readers is “does mean reversion still work?” The last time I wrote about this topic was in 2015, a long time ago, in the post “The Health of Stock Mean Reversion: Dead, Dying or Doing Just Fine” I did not realize it had been so long. Time to look at it again. The

In my last post I discussed SPY/TLT rotation strategies. Today, I will be using the same ideas from the post but on a basket of bond ETFs. The Basket The first difficult decision one must make is what ETFs will be in the basket. What we choose here, can have a big impact on the results. I wanted to

For my retirement accounts, I like to trade ETF strategies that require little work. One strategy we have all seen is the SPY/TLT strategy. There are many flavors of this concept. Some pick the best one over the last N months. Then there are different ways of allocating a portion of the portfolio to

I have a Google Home in my bathroom that I play a morning routine while I shave, brush my teeth and get ready for the day. One step is to play The Indicator podcast from Planet Money. This morning they were talking about how “2018 was one of the most volatile years on record for the stock

As I have mentioned in several interviews, I am always looking for new strategies. One area that fascinates me is stock options. Because it is difficult to get good data and to do backtests, I believe that there are good edges here to be found. A few weeks ago, I found myself with lots of time and

While writing my presentation for TradersFest 2018, I wanted to add the trader’s emotional curve. But looking at it closer, it did not capture my feelings as I go through the cycle of up and downs of trading a strategy. Here is my curve. I have been on every part of this curve multiple times.

A reader pointed me the November 2018 issue of Technical Analysis of Stocks & Commodities to an article about a trend following indicator on S&P500 stocks. I liked the concept of the indicator and the article had backteted results and AmiBroker code. How could I resist not looking into this?
