The Turnaround Tuesday Trading Strategy

The Turnaround Tuesday effect happens from the close of Monday’s trading session until (at least) the close of Tuesday’s trading session. The effect is no myth!

This article looks at the Turnaround Tuesday trading strategy. Buying on weakness on a Monday seems like a good trading strategy. The Turnaround Tuesday effect exists, but it improves by adding a filter.

What is Turnaround Tuesday?

We have previously written about potential trading strategies based on the day of the week effect, particularly on Mondays: the stock market has a tendency to change direction and move in the opposite direction of the previous move prior to Mondays.
For example, if the market is down on a Monday, you are likely to get above-average returns in the next few days. Opposite, if Monday is very strong, the return over the next days is substantially lower compared to a down day.

The mother of all Turnaround Tuesdays

To give you an example of a Turnaround Tuesday just look at what happened on the mother of all Turnaround Tuesdays: the Black Monday on the 19th of October 1987.

After a dramatic day on Monday the 19th of October, the market rebounded 5.3% on Tuesday and 9.1% on Wednesday!

Turnaround Tuesday trading strategy number one:

We test the following strategy:

  1. Today is Monday.
  2. The close must be at least 1% lower than Friday’s close.
  3. If one and two are true, then enter at the close.
  4. Exit at the close on Tuesday.

This simple trading strategy looks pretty good:

  • Number of trades: 163
  • Average gain per trade: 0.7%
  • CAGR is 3.9%
  • Exposure/time in the market: 2.25%
  • Win ratio: 63%
  • Average gain per winner: 1.75%
  • Average loss per losing trade: -1.05%

Turnaround Tuesday trading strategy number two:

We test the following strategy:

  1. Today is Monday.
  2. The close must be lower than the open.
  3. The IBS must be below 0.2.
  4. If 1-3 are true, then enter at the close.
  5. Sell at Tuesday’s close.

This returns the following compounded equity curve in SPY from 1993 until September 2021:

  • Number of trades: 247
  • Average gain per trade: 0.41%
  • CAGR is 3.5%
  • Exposure/time in the market: 3.4%
  • Win ratio: 60%
  • Average gain per winner: 1.23%
  • Average loss per losing trade: -0.82%

The return is substantially higher than any other day.

The same strategy as above produces the following profits on the different weekdays (1 is buying the Monday close, 2 is Tuesday’s close, etc.):

As you can see, buying at the close on a Monday is twice as good as buying on the Tuesday close, not to mention the other days which are even less profitable.

Thus, the Turnaround Tuesday is no myth. Buying weakness on Mondays has turned out to be a profitable strategy for about 30 years.

Flipping the Turnaround Tuesday

Let’s flip the strategy:

  1. Today is Monday.
  2. The close must be higher than the open.
  3. The IBS must be above 0.8.
  4. If 1-3 are true, then enter at the close.
  5. Sell at Tuesday’s close.

Buying on strength on a Monday is not a good idea:
