The two charts below show the strategy’s hypothetical performance in the aggregate capitalization-weighted US equity market from February 1, 1928, to December 31, 1999 (Chart 1, right y-axis: linear; Chart 2, right y-axis: log; data source : CRSP):

The blue line is the full return on daily momentum, a timing strategy being tested. The black line is the total return of the buy and hold strategy. The yellow line represents the total return on cash. Gray bars are US recession dates.

The red line is the total return of the X/Y portfolio. The X/Y portfolio is a mixed portfolio with an allocation to stocks and cash that corresponds to the timing strategy’s cumulative trailing exposure to each asset. The timing strategy spends 55% of its time in stocks and 45% in cash. The appropriate X/Y portfolio is then a 55/45 stock/cash portfolio, a portfolio that is constantly rebalanced so that 55% of its assets are in stocks and 45% of its assets are always in cash.

I introduce the concept of the X/Y portfolio, which can serve as a reference or control sample. I need this benchmark or control sample to perform a proper statistical analysis of the performance of the timing strategy. If “timing” itself has no value and only asset exposure matters for returns, then any timing strategy is expected to return the same as the return on the corresponding X/Y portfolio. The returns are expected to be the same because the cumulative asset exposures are exactly the same – the only difference would be the specific timing of the exposures. If the timing strategy statistically significantly outperforms the X/Y portfolio, then we know that it adds value through timing. It takes the same aggregate asset exposures and turns them into “something more”.

The green line is the most important line in the chart. It shows the cumulative outperformance of the timing strategy relative to the market, defined as the ratio of the trailing total return of the timing strategy to the trailing total return of the buy-and-hold strategy. It takes its measurement from the right y-axis, which is shown on a linear scale in the first diagram and a logarithmic scale in the second.

Development Process — Tick Backtesting

As you can see in the chart, the timing strategy performs incredibly well. From the beginning of 1928 to the end of 1999, it produced a total return of more than 5,000 times the total return of the market, with lower volatility and a lower maximum draw. It earns 25.1% annually, 1,400 basis points more than the market. The idea that a timing strategy can beat the market by 14% per year, not just in the short or medium term, but over seven decades, is almost inconceivable.

Now imagine it’s late December 1999 and I’m trying to sell you this strategy. What would be the best way to sell it? If you know the current intellectual fad in finance, you know the answer. The best way to sell it would be to package it as a “data driven” strategy. Other investors use investment strategies based on sloppy, unreliable guesswork and guesswork. However, I use an investment strategy whose effectiveness is shown by the “data”. All the success you see in established fields of science – physics, chemistry, biology, engineering, medicine – you can see from my strategy, because my strategy started from the same empirical, evidence-based approach.

Based on what we’ve seen, active investors who focus their investment processes on “data” do no better in real-world investment environments than active investors who invest based on their own market analysis or investors who simply index. . It is clear that some investors have done extremely well using data-driven approaches, while others have done poorly – some,

Badly, to an extent that was not previously expected. The lack of consistent outperformance of the group as a whole has made me increasingly skeptical of data-driven investment approaches. In my opinion, such approaches are given too much credence and respect and not enough scrutiny. They have a reputation for scientific credibility that they don’t deserve.

In this article, I will use the timing strategy presented above to distinguish between valid and invalid uses of data in an investment process. In traditional practice, we take a proposition or strategy and “backtest” it—that is, test it against historical data. We then draw probabilistic conclusions about the future from the results, conclusions that become the basis of investment decisions. To use the timing strategy as an example, we take the strategy and test it until 1928. We are experiencing very strong performance. From this performance, we conclude that the strategy is “likely” to perform well in the future. But is this conclusion correct? If valid, what makes it valid? what is its basis? I will answer these questions in the piece.

Well, if we want to use the results of a backtest to make statements about the returns investors are likely to get if the strategy is used in the real world, the first thing we need to do is properly account for fair value. – global frictions related to the transactions of the strategy. The daily momentum strategy trades extremely frequently, trading on 44% of all trading days and accumulating a total of 8,338 trades during the tested period. In addition to brokerage fees, these transactions also include the cost of selling and buying, which is equal to the difference between the two and is incurred on each round trip (buy-sell pair).

In 1999, the most liquid ETF on the market—the SPDR S&P 500 ETF, SPY $ SPY—had a bid-ask spread of less than 10 cents, or about 0.08% of market value. The lowest available transaction fee from an online broker was around $10, which, assuming a trade size of $50,000, was about 0.02% of assets. These add up to 0.10% as a conservative friction or “slippage” cost to apply to all trades. Of course, the actual average slippage cost over the period 1928-1999 was much higher than 0.10%. But an investor who has been using this strategy since 1999, as we will, will not see this higher cost; you will see a cost of 0.10% which is the cost we want to include in the test.

As can be seen, with proper consideration of slippage costs, the annual return falls from 25.1% to 18.0%, which is a significant drop. However, the strategy continues to strongly outperform, beating the market by more than 700 basis points annually. We therefore conclude that an investor using this strategy since 1999 is likely to enjoy strong returns – perhaps not 18% or more, but returns that will more than likely beat the market.

What Is Backtesting? Definition & Example

The main danger to our conclusion is the possibility that randomness controls the performance seen in the backtest. Of course, we need to clarify what exactly the term “random” means in this context. Let’s take an example. In May 2015, the New York Rangers played the Tampa Bay Lightning in Game 7 of the Stanley Cup Semifinals. The game was a Rangers home game at Madison Square Garden (MSG). The following chart shows the Rangers’ performance in game seven at MSG up to that point:

As you can see, the Rangers were a perfect 7-for-7 in home games. Given that past performance, would it have been fair to conclude that the Rangers were “likely” to win the seventh game they were set to play? Intuitively, we recognize that the answer is no. The “7-for-7 in home game weeks” statistic is a purely random, random event that has little if any bearing on a team’s true probability of winning any given game (Note: the Rangers lost the game).

(1) The probability of Rangers winning any seventh home game is 50% or less. There will be seven home games in sevens in this period and Rangers will win all seven – a result with a probability of less than 1%.

Since the occurrence of (1) is extremely unlikely from a statistical point of view, we are forced to accept alternative (2). The problem, of course, is that defining this week’s games as a “sampling” of how likely the Rangers are to win the next game is completely invalid. The pattern is skewed by the fact that we
