Strong Seasonality Stocks for August

Copy link to section

The statistics below are based on the historic monthly opening and closing prices. Therefore, gains or losses within the month may be larger than those disclosed below. For example, a statistic may say the biggest rally on a monthly basis was 15%, but during the month the stock could have been up 20%, but dropped to only finish the month up 15% (intra-month losses could also be bigger). This is why it is also recommended traders combine these statistics with other strategies, which help control risk and lock in profits.

Buying at the open and close of the month is also somewhat arbitrary. There are more precise times to take trades. Focus on seasonal opportunities that align with strategies you are already using.

This is the raw data. How you interpret it, and what you opt to do with it, is up to you.

All stocks do at least 100K in average daily volume.  All stocks with an average gain of less than 2.5% have been excluded.

Final Word on the Strong August Seasonality Stocks

Copy link to section

This is the raw data. What you do with it is up to you. All traders are encouraged to do their own research and apply their own strategies if utilising these statistics.

Each stock has a different risk profile. While the ‘average gain’ statistic is a key metric, it doesn’t tell the whole story. Making 7% may seem attractive but when looking at the volatility it may be more than you are willing to handle. Therefore, look at the all the data when deciding what to trade. Also, apply other technical and fundamental metrics to help zero-in on exact entry and exit points. Seasonality is not covered in my stock trading course, because it is a not a requirement for successful trading. That said, it is an additional tool you can use.

Losing trades WILL happen. Don’t risk more than 1% of your trading account on a trade (risk = difference between entry price and stop loss price, multiplied by the number of shares). There is always a risk in trading, and you can lose much more than you expect (even when you think you are only risking 1%). Remember to keep an eye on the share price.
