FB Signals Weekly Equity

FB (Facebook) Signals – Weekly

These trading signals for FB were selected from 1,210,488 backtest results for their reward/risk and parameter sensitivity characteristics. While backtests don't typically provide reliable signals which can be counted on moving forward, many swing traders are curious as to what buy and sell signals would have worked up until now.

FB Signals Weekly

For the 327 week (6.2 year) period from May 14 2012 to Aug 17 2018, these signals for Facebook, Inc. (FB) traded as directed would have yielded $494,263 in profits from a $10,000 initial investment, an annualized return of 87.3%. The long-side profit (buy/sell only, no shorts) for the signals was $170,258, an annualized return of 58.9%. If you had bought and held the stock for the same period the profit would have been $31,389 (an annualized return of 25.5%). The trading style was Long & Short, meaning that you would be long or short the security at all times.

For this type of strategy, not every signal is acted upon and signals are often reinforced. If you are long in the security, buy signals can be ignored, for example. Similarly if you are short you can ignore sell signals. For this particular FB strategy there were 320 buy signals and 31 sell signals.These led to 24 long trades of which 18 were profitable, and 24 short trades of which 19 were profitable.

This is a weekly strategy; weekly OHLC data is used to derive all signals and there is at most one buy and sell signal and one trade per week. Drawdown (the worst case loss for an single entry and exit into the strategy) was 22% vs. 57% for buy-hold. Using drawdown plus 5% as our risk metric, and annualized return as the reward metric, the reward/risk for the strategy was 3.20 vs. 0.41 for buy-hold, an improvement factor of around 7.8 .

The MASC BAO Trading Strategy

Finding MASC BAO strategies on randomly selected stocks

The MASC BAO trading strategy frequently shows up in the top ten backtests. It has the distinction of being the strategy used in the most profitable backtest SignalSolver has ever found--AAPL Monthly MASC BAO which would have generated over $400 Billion from $10,000 invested.

Here we look for MASC BAO strategies which beat Buy/Hold for stock symbols A through F (i.e. an arbitrary selection) using backtests run against daily, weekly and monthly data for each stock. The point of the exercise is simply to show that you can usually find a MASC BAO algorithm that beats buy or short-hold. Here are the results:

MASC BAO backtest results

Each table shows the difference between the buy-hold returns and the returns from the MASC BAO strategy. Strategy returns are shown in three parts, those for the long only, short only and combined long&short (L&S). Also of interest are the Reward/Risk numbers (higher is better).

You can see that for all 18 data sets, SignalSolver was able to find MASC BAO trading algorithms which beat buy-hold or short-hold. Many were significantly better, such as the 83% annualized return for E daily (vs 0% for buy-hold), however a few were only marginally better such as the 15.3% for D weekly (vs. 12.8% for buy-hold).

More about the MASC BAO strategy

MASC BAO roughly follows a "buy the dips but sell at the first sign of trouble" methodology. The MASC BAO strategy for the Percentage Band is this:

  1. A BUY signal occurs if, in a given period, the price fails to rise a fixed percentage above the last sale price.
  2. A SELL signal occurs if the price goes below a fixed percentage below the median price (i.e. half H+L) of the previous period.
  3. A sell signal turns a bullish position to bearish at the open of the subsequent period.
  4. A buy signal switches a bearish position bullish at the close of the period.
  5. You only respond to one signal per time period.

For example, if the last sale price was 100, a buy signal for [MASC 10% PB] would occur if the price in a given day, week or month failed to go above 110. This could be dangerous if you were trading short or long and short. If you were short and the price broke out to new highs, there would be no buy (cover) signals and you would lose all if the price went to double your short sale price. If you were just trading long, you would be simply be locked out of a bull run.

For other bands, the percentage value is calculated on the band in use and added into the reference (in this case last sale price on buys, median price on sells), as described here. Interestingly, only 4 bands emerged from this study: SMA (Simple moving average), TMTR (Trimmed mean of the true range), Bol1 (Bollinger band 1) and the PB (percentage band). Other bands often gave good results, but these four bands gave the best results.

As always, good backtest results don't necessarily translate into future profits for any trading strategy.

AMZN top 4 algorithms day by day

The out of sample multi-algorithm approach was quite successful for AMZN (see results) so lets do it live and see how it ends up. On Dec 21st, I did the optimization using the EMA band and Figure of merit optimization I have been talking about in the last few posts. For the next 25 trading days and maybe beyond, I will update the following trading guidelines for the top 4 algorithms. All these strategies were found using SignalSolver.

Update Feb 23rd 2017: Summary and Wrap Up: 10, 25 and 42 day

I'd like to wrap up this study by publishing the 25 day results as promised. Since yesterday was day 42, I've also added in the 42 day results although the algorithms were never expected to have a 42 day lifetime.  I'm happy to report that the algorithms were profitable. As predicted, the 10 day results gave the best average annualized return (121%) for the algorithms, with a noticeable fall-off in the 25 day (56.6%) and subsequent 42 day (39.3%) results:

This study was done over a time period of unusual gains in the stock market and AMZN, the algorithms for 25 day and 42 day failed to keep up with buy/hold. But if you focus on that, you would be missing the most important point--that following the algorithms eliminates all the buy/sell/short/cover decision making.

The Strategies

The following sections were updated daily during the course of the live study, so that readers could follow along with the four algorithms as they progressed day to day. The last day published this way was day 20 which is shown below.

AMZN Top 4 Algorithms: performance update at day 10 (Jan 5th 2017)

Happy new year. If you had been following along for the last 10 trading days you would have seen me publish a daily description of each the trade before and after it was made, including the type of order to be placed and when, so there was no cheating--this was a live, real-time test.

At trading day 10 (yesterday Jan 5th 2017) I am pleased to report that all 4 algorithms are showing a profit: For $10K invested in each, alg 1 profit was $258, alg 2 $142, alg 3 $558, alg 4 $147. This includes all trading costs ($7 per trade) and was for Long and Short sides combined (see L&S columns below). Just the long side did almost as well (Long column below). Of 15 total trades, 13 were profitable. Average profit was $276 or around 95% annualized return. For the same period, buy-hold return was $161 or 50.6% annualized.

The point to note here is that the combined algorithms showed a profit. Not only that, they did a much better job of exploiting the price movements than either buy-hold or short-hold. The SignalSolver algorithms make buy-sell decisions based purely on numerical analysis of  past price movements. As a technical analysis methodology I must say it did a good job in this case.

I will continue to give daily trade instructions just after each NYSE open. I will report performance out again on day 25, the end of the test period, although I expect it to decline as the algorithms age. After that we need to re-optimize to new algorithms as I expect performance of these 4 to fall off.

 

AAPL $31,000,000 trading strategy, equity curve

AAPL $31,000,000 Algorithm

This AAPL trading strategy would have given a return of $31,712,009 for every dollar invested in December 1980. That's 123,000 times better than buy-hold, with nearly four times the annualized return (61.4% vs 16.7% for buy-hold) and roughly half the drawdown which  amounts to over six times better reward/risk than buy-hold.

AAPL $31,000,000 trading strategy: Table of results

AAPL $31,000,000 trading strategy: Table of results

This is a variation of the MASC BAO algorithm which I have published before,  except this time the buy point is related to a Bollinger Band instead of just the sell price. I found it using SignalSolver.

Here is the strategy:

In this case the Bollinger band is the 7 period StdDev of median prices (monthly (H+L)/2), and the band is built around the last sell price, not the usual method of building it around a moving average. A little unconventional but it worked wonderfully. Algorithms with buy signals based on sell price often get stuck, but this one didn't. Sell signals were based on a raw Percentage Band built around the monthly median (H+L)/2 prices, just like the original version of this.

Here is the equity curve:

AAPL $31,000,000 trading strategy, equity curve

We are looking at quite a bit of reinforcement on buy signals, but sell signals tend to come in ones or twos. There are some dual signal months but not too many. Dual signals will trigger a trade for this algorithm.

Moving onto the scans, you can see that there is a single area of profitability:

Annualized return vs. buy and sell point for the AAPL $31,000,000 trading strategy

Getting the buy or especially the sell point wrong would have led to a complete loss, as this algorithm was run Long and Short (you were either long or short at all times). Here's the entire parameter surface, for completeness:

AAPL $31,000,000 trading strategy, parameter surface

A bit of a steep sided mesa, but a reasonably large plateau.

Since I found it in June, the algorithm has added about 3%, but it hasn't traded and is still long.

AAPL MASC BAO Update Aug 4th 2017

The algorithm has added around 40% since publication in Dec 2016, return on $10K would now be $432,155,847,777 . There have been no signals or trades and the position remains long.

AAPL MASC BAO Update 5/4/2021

Just to round this out, the algorithm finally hit the dust in Aug 2020 making a total loss. Here's how it performed since its original publication in 2016. A mixed bag really, It kept you on the right side and did around 30% better than the underlying until about 3 years after publication, then broke down.  Like all algorithms based on backtests, they work until they don't. And you can't predict when the end will come.

In case you are wondering, re-parameterizing would have helped. A sell point of 27.28% or greater would have given you the same result as buy-hold, but without trading, so not terribly meaningful. But that's the best possible outcome for this algorithm over the last 5 years, a 45% annual return.

Multi-algorithm test results for NUGT (4 algorithms)

Multi-algorithm study results for NUGT DUST and X

In the interests of scientific method, I'd like to continue the multi-algorithm study by discussing the worst results, those for X (United States Steel Corp. ), NUGT(Direxion Daily Gold Miners Bull 3X ETF) and DUST(Direxion Daily Gold Miners Bear 3X ETF). There was plenty of potential for disaster in these stocks, very large swings indeed. In fact, as you shall see, these often led to total loss of capital because the algorithms were run both Long and Short--if the stock price doubles and you are short, you are wiped out. All the results for the study can be found in the spreadsheets.

While the September and Jan optimizations were almost all lossy, the Jun optimizations led to profits for the 50 and 99 day horizons, so overall, losses were fairly neutral. But the technique clearly failed to exploit the price movements of X. Look at the January buy-hold figures, there was plenty of room for profit on the long side, but harshly negative profits for the algorithms.  Similarly for Sept optimizations on the short side.

The January optimization results are the worst. 25 days into the test, 3 out of the 4 algorithms had gone belly up with a complete loss. Before the 99 days had elapsed, the fourth algorithm had also died off. Not that difficult to understand, though. For the Jan 15 to Jan 16 optimization period the stock price had dropped from $42 down to $3.50, consequently, all the algorithms had a strong short bias. Just at the start of the out-of-sample runs, the stock price started rising, from $3.50 up to $21 at the end of the 99 days. Oh well. On the positive side, most of these losses were offset by the June optimization results, so it  ends up being pretty flat returns overall, but sadly leaving these huge swings unexploited.

While the June optimizations led to some decent exploits, the Jan results were again pitiful, stock price dropped from $1000 to $50, and the algorithms had a buy bias, so not a good result.

 

 

Multi-algorithm results for UWTI

Oil had a rocky year, lets look at how our multi-algorithm approach worked on an oil related stock, UWTI (VelocityShares 3x Long Crude Oil ETN). In this post, I'm just going to summarize the results:

Briefly, the method used is to run SignalSolver to find trading systems which worked for a 250 day period, then run these trading system against the data immediately following the 250 day period to see how they performed. This is known as out-of-sample testing as none of this following data is included in the optimizations.

The methodology is identical to my previous posts. If you need more details you can download the results spreadsheets, or download SignalSolver and run the optimizations yourself. I have omitted the result for the Return optimization on the PB band this time because I think we have established that the Figure of Merit optimizations usually work better. They do here.

The idea is behind multi-algorithms is that using a single algorithm is risky, but running multiple algorithms at once averages out your risk and leads to more consistent and more efficient (since you are sometimes out of the market) results. Here, we averaged over the top 4 algorithms for each period.

You can see that the multi-algorithmic approach gave very good results for the 25 day (5 weeks of trading) and 50 day runs. If you look at the buy-hold profile you can see that you would have had a rough time guessing long and short entry and exits to get the same results. Not saying it couldn't be done, but using the multi-algorithmic approach would have given nice returns for UWTI with absolutely zero guesswork. And its based on sound numerical analysis, not hunches and tweets. Is anybody listening? 🙂

Multi-algorithm analysis for FB (Facebook)

Today, I'll just throw out some more results from the multi-algorithmic testing I've been doing with SignalSolver. This time for Facebook (symbol FB). This is a stock which moved a lot in the time-frames used in the study. Could SignalSolver correctly predict and capitalize on these price movements? Let's see...

Optimizations for June 2015 through June 2016

As described in the methodology and the AMZN results, two optimizations were run on the June 2015 through June 2016 stock price data, one which rewarded raw returns using the Percentage Band, the other which rewarded more consistent returns and using the EMA band. First, lets look at Buy-hold performance for the subsequent periods:

Now lets see if the algorithms were able to exploit these price movements.

Results of the Return Optimization:

Now, the results for the Figure of Merit optimizations:

and the multi-algorithm averages:

One difference to note is that the return optimized algorithms were started out in a long state (because the End State vote indicated Long 7 to 1), whereas the FOM optimized algorithms were started out of the market because there was no good consensus. Accordingly, these returns would have been realized with lower capital.

Jan 2015 to Jan 2016 FOM Results

Here's the buy-hold results:

A pretty dramatic rise at the end of Jan 16. Luckily, all the algorithms were started long, so we got a piece of the action:

Averages:

Averaging more algorithms simultaneously gave better results, for the most part. In fact for the 25 and 50 day we actually beat Buy-hold for the higher averages.

 

 

 

FB Sept 2014 to Sept 2105 FOM Optimizations

Buy-hold:

Another impressive set of returns (if you had guessed long). How did the algorithms do?

Good 10 and 25 day results, but hanging on for 50 trading days would have knocked a big hole in your profits. But,  had you held on for 99 days you would have beaten buy-hold very nicely.
